Carbon County, Montana
When Carbon County, MT initially implemented a new addressing system, it was met by confusion among first responders and the public. To implement E-911 services that would shorten emergency response times and save lives, the county needed an accurate, centralized database of new addresses easily accessible by public safety personnel and citizens.

Carbon County, MT has produced a TerraGo GeoPDF digital atlas to improve emergency response times for non-GIS trained public safety personnel and first responders in support of an E-911 services implementation

A Case Study of the Trinity
The first decade of the twenty-first century has led or forced many in the surveying profession to adapt to and embrace the technological applications of geographic information systems (GIS). The progress that has been made in the areas of Global Positioning System (GPS) and Mobile Light Detection and Ranging (LiDAR) has allowed surveyors to accurately collect more topographic shots than ever before. GIS, in this instance ArcMap, allows surveyors to visually see and compare their datasets as features change over time, either by natural causes such as erosion or by man-made causes like construction.

Agriculture has always played an important role in sustaining the health of rural economies across Europe. North Rhine- Westphalia, the westernmost and largest Federal State of Germany, is no exception.

More than 50 years ago, the European Commission of Agriculture and Rural Development created the Common Agricultural Policy (CAP) to help meet the needs of local farmers. Initially, the program was designed to encourage agricultural productivity, ensure a stable supply of affordable food, and bolster Europe’s agricultural sector following World War II.

Today, CAP has evolved to promote a healthy, competitive agricultural industry across Europe. To receive subsidy payments, farmers must meet certain standards concerning public health, animal and plant health, the environment, and animal welfare, and they must keep their land in good

Replication in the Real World
Mondi Ltd, an international vertically integrated forestry, pulp and paper company, needed to replace their 10 year old customised GIS platform. In doing this, they needed to maintain a centralised corporate database but edit spatial data locally, despite a very poor ICT network. The answer was found in applying an ArcGIS 10.0 replicated geodatabase solution, using a 2-way replication configuration. In addition, the solution had to be integrated with a third party Forest Management database such that the two systems remained synchronised.This was achieved using multi-versioned views. This presentation will highlight the database design issues, and system limitations that were encountered and the solutions found that resulted in a successful implementation of an Enterprise level Replicated Geodatabase in spite of very poor network connectivity.Critical elements were careful database design,rigid workflow procedures and thorough user training. These results will hopefully assist other users in similar circumstance achieve success in their environments. Mondi Ltd

Urban Renewal Design Template
Urban Renewal Design Template The Urban Renewal Design Template provides a staged development plan in the renewal of a historic, platted community in need of assistance with the following: an expanded road network, Section 8 housing, employment, recreation, and education facilities, for a better connection to community businesses, county facilities, and housing improvements. The Template addresses the problem of an urban area enclave; when a community lacks a connection to the outside world, both geographically, psychologically, an inability to offer a sustainable environment occurs. Transportation improvements will connect many dead end roads with the connector roads shown; housing, phased in with the proposed road construction and other improvements, will define the renewal project in stages. In addition, an inventory of area businesses and facilities offers some opportunities for the development of a local labor source. Close proximity to employment and the required training for a stable force can occur within walking distance to employment facilities; a great feature for employment training and opportunities within the community, and in line with the Enterprise Zone program.

ArcGIS, DVR (Digital
ArcGIS, DVR (Digital Video Recorder) CCTV, Video Cameras, and DSL, Monitoring System Rapidly advancing digital hard drive technology, falling camera prices with enhanced capabilities, and high-speed Internet saturation, have all combined to deliver an extremely efficient, highly affordable way to improve security, productivity, and public satisfaction. DVR CCTV technology is affordable and available for many collateral uses such as observation of coastal areas from an operations center for a comprehensive, risk-based, all-hazard Emergency Management program. The Hernando County Office of Emergency Management Application The decision to provide the Office of Emergency Management and Hernando County with real time video of the selected Coastal sites and facilities as shown in the original Hernando County UC 2004 Map Gallery entry required Hernando County resources and interest across the organization. The interoperability of ESRI GIS on the Windows platform with DVR CCTV technology inspired the Hernando County Government Offices and peaked the interest of Technology Services, Community Services, the Hernando County Government Broadcasting, and the Sheriff’s Office. This 24/7 surveillance system protects citizens and improves public safety and awareness at all County facilities. The selected Coastal Zone camera sites are a subset of the entire network to eventually include all County facilities. The system provides 'hot links' from desktop GIS to live video cameras via a DSL Internet connection. The surveillance system has added value during storms and events as a cost effective, interactive tool. With high-speed DSL Internet and ArcGIS ‘hot links’ the Office of Emergency Management has a real time advantage at any strategic locations in service for a better focus during emergency events, all in one system! How It Works Most DVRs (Digital Video Recorders) can be set-up to record on a schedule, when an alarm is tripped, or when there is motion in the camera's view, as detected by the DVR. The user can block out constant motion quadrants such as passing traffic. Most pre-existing surveillance cameras are already compatible. Users don't need to purchase new cameras; any existing cameras take a separate power cable and (BNC) video output connection. If the user purchased an observation system with din plugs or telephone jack cables, upgrade the cameras to normal professional grade surveillance cameras, perhaps with zoom and night-vision features. Popular DVR units are equipped with upgradeable and portable hard drives. DVR units can store from two days to two weeks of camera footage, depending upon the adjustable recording frame rate, and the amount of activity in the view of the camera. Personally set every unit at maximum resolution, and at the fastest selectable recording frame rate. When the hard drive memory is full, the system will begin writing over the existing camera footage. The user has the ability to ‘go back in time’ to any event, zoom in for details, or burn high-resolution camera footage onto CDRWs or DVDs whenever a need for visual evidence as for a record occurs. In an event, transfer the digital information before the DVR has over-written. It's that easy. Otherwise, let the system re-write and forget about changing and replacing the media until necessary.

Effects of Climate Change
Abstract Whether or not you believe in human-caused Climate Change it is clear by common consensus that the world's climate is changing and that burning carbon-based fuels cannot help and might even accelerate changes in the climate. Any mitigation efforts to stave off the worst effects of Climate Change (sea level flooding, droughtdriven starvation etc.) will involve substantial investments across the globe and without question will cause increased energy costs.

Abuja is one of the fastest growing cities in the sub-Sahara Africa. The city lacks the modern management techniques for an effective crime mapping, monitoring and management to meet the attainment of liveable environment despite its aesthetically pleasing outlook of a modern city. The cities of the developed world are managed with the intelligence provided by Geo-spatial technologies. The advances in space technologies have made the onerous task of managing crime possible. However, the availability of these technologies has not been exploited, utilised nor domesticated by various institutions charged with the responsibility of city planning and management to attain secure and safe environment in Nigerian urban and rural communities. Geographic information systems, remote sensing and allied technologies have manifested in various forms in the last four decades particularly since the launch of LANDSAT earth observatory satellites these has provided baseline information for intelligence gathering. The very high resolution images provided by the new generation of satellites have made the integration of GIS/RS for urban crime mapping not only possible but also effective for day-to-day running and management of many aspects of city life. The NigeriaSat-2 and Ortho-rectified Quick-Bird images, basemap, master plan and questionnaires were used to generate the crime dataset which was later aggregated to show the crime hotspots and Coldspots areas within the residential districts of Abuja Federal Capital City, Phase 1. A proximity analysis was later carried out to ascertain the relationship between crime hotspots and Coldspots and police divisional stations, slum settlement as well the various parks and gardens in the study area. The result showed significant correlation between parks and gardens and crime as well as positive correlation between slum settlement and crime in the study area.

The availability of over 45,000 accurately surveyed ground points covering an area of 1,000 km2 in central Eritrea has enabled comprehensive accuracy assessments of elevation mapping from IKONOS, GeoEye-1, WorldView-1 and WorldView-2 stereo satellite photos. The ground survey points were acquired for a base metal mining exploration gravity survey. All of the ground points were surveyed with Real Time Kinematic GPS instruments and are accurate to 2 cm. The IKONOS, GeoEye-1 and WorldView-1 stereo photos were each registered to a single ground control point, and the WorldView-2 stereo photos were registered to two ground control points. Each of the stereo pairs covers a slightly different ground area.

Mobile Mapping Systems (MMSs) have attracted considerable attention from the viewpoint of application to road management and maintenance. MMSs can help evaluate the condition of asphalt pavements. In a road space, it is essential to keep the road surface in good condition, without surface damage such as cracks and patches. Human inspection is still widely used for road management to detect such damage. However, manual surveys are time-consuming and not very effective. Therefore, the successful automation of surface damage surveys will help reduce the cost of detecting damage and provide more objective and standardized results for road management. Our previous study attempted to visualize surface normals for point clouds of asphalt pavements in both good and poor conditions. However, our visualization was unable to help us clearly discriminate between good and bad surface pavement conditions. Thus, the purpose of this study is to examine and test a method that uses MMS to evaluate road conditions effectively. We try to evaluate surface conditions through colored point clouds assigned values of 8-bit RGB color components that map the values of the surface normal and the curvature in a point cloud. An experiment shows that our method generates point clouds that successfully enable us to distinguish between good and bad road surface conditions. Our result also indicates the importance of selecting optimal values for the radius of the point cloud in calculating curvature.

NGA is building a Content Maturity Model (CMM) to rate geospatial-intelligence (GEOINT) products, services and data. The CMM concept enables consumers of content to understand its quality and suitability for their mission, and also to have a conduit by which to provide feedback to NGA. The consumer rating capability will improve the feedback mechanism between consumers and producers of content, enabling NGA to provide rapid quality improvements and, subsequently, consumer application corrections. This initiative supports the NGA Strategic Objective on Content by creating and proliferating GEOINT content which is imperative to consumer requirements. CMM data quality components will be searchable, discoverable and provide indicators for consumers which informs them whether or not they are in possession of the best data available. The CMM also supports the Agency’s transformation from a product-focused model to a data-focused provisioning solution. In this new data-centric environment, consumers will be serving or linking to many sources of GEOINT and a mechanism to receive and provide quality feedback will be critical. Consumers require indicators of data quality. The CMM is the means to benchmark geospatial data quality for consumer analysis as well as the data’s own evolution.

In recent years the developments of small electronics prototyping platforms such as Arduinos and Raspberry Pi’s, created a new whole market from electronic equipment and Ideas for various sizes projects. It didn’t pass too much time for developers to combine all these sensors and platforms and to create complete and more sophisticated navigation systems and find their way inside small remote controlled airplanes. The next step, the installation of a small digital camera it was pretty much expected due to human curiosity. The results were significantly changed the geospatial community. It was very obvious since the beginning of this technology that we had definitely find a cheap and reliable solution for aerial imaging. The necessary steps for designing and executing an aerial image acquisition mission are far from being well defined. If we isolate the involved products one by one, we would see impressive specifications: High resolution DSLR or compact cameras, navigation systems with fast CPUs, reliable GPS units and radio receivers. But when all these stuff we are combining into a UAV (Unmanned Aerial System) fuselage and you are exposing it to aerodynamic forces on an environment full of uncertain parameters like weather and atmospheric conditions then, the UAV as an imaging sensor, needs to be studied further. The overall of our research is to establish the necessary steps for preparing and executing photogrammetric aerial image acquisition. The final products should be vertical or near vertical well defined images with known exterior orientation, high resolution with small GSD and with adequate sidelap and endlap for supporting stereo vision.

A significant technological advance has been achieved by applying concepts and software developed for oil and gas exploration seismic data processing to produce detailed elevation maps from the new generation of high resolution satellite photos. We call this a geophysical processing system since the system is developed by geophysicists, using geophysical processing tools, including a 3D seismic workstation, and the processors never view the photos in stereo. PhotoSat has recast the stereo satellite elevation mapping problem so that it closely resembles oil and gas exploration seismic processing.

The objective of this work is to develop new methods for efficient automatic 3D modeling of existing industrial installations from point cloud data. Traditionally, cylinder feature extraction algorithms utilize 5D Hough transforms, resulting in impractically high computational complexity. A more efficient approach uses a 2D Hough transform to estimate orientation followed by a 3D Hough transform to detect position, but still has extensive runtimes and lacks robustness in dense point cloud data.

SpecTIR Releases Free
SpecTIR has made available a number of airborne hyperspectral imagery data sets for research, training, and educational purposes. They will be available from the SpecTIR website and cover a wide variety of subjects which include: • Gulf of Mexico coastal National Wildlife Refuge wetlands prior to oil landing onshore • A sample of oil on the water at the Deep Water Horizon well head on June 6, 2010 • Agricultural crops and vegetation • Geologic samples from Cuprite and Virginia City NV • Coral Reefs from the Red Sea • Wetland and Submerged Aquatic Vegetation from the Sacramento River Delta and • Urban and urban vegetation imagery from Reno, NV. The data was collected with the ProSpecTIR VNIR/SWIR hyperspectral sensors, which are typically used to collect spectral and spatial information for applications such as long-term environmental monitoring. The samples include the radiance and reflectance files, which are calibrated and navigated, so that they can be used as a GIS layer. These samples are significant because they demonstrate the practical uses of spectral imagery. The sensors are operated from small aircraft, and can be at any location in the world in a matter of hours or days. Once onsite they can capture information that makes it possible to detect and monitor minute changes to the environment, water, or vegetation. Over time, this becomes a very powerful mapping tool that can be used to manage responses to both man-made and natural disasters. Mark Landers, SpecTIR’s president states “A clear cut example of the use of this technology is the images that we collected from the coastal wetlands of the Gulf of Mexico as the oil was heading for the shore in June of 2010. We were able to establish a baseline, prior to the oil, that can be used initially in the wetland vegetation damage assessment work, and in the long term will help to measure and guide the recovery efforts of the Gulf States.” About SpecTIR LLC SpecTIR LLC is a Small Business with offices in Virginia, Maryland, California, and Nevada.

Nowadays, sharing and querying spatial data through Internet has been become ubiquitous and easier in term of visualization and analysis. Thus, GIS (Geographic Information System) is no more an isolated application used by a limited number of users, but essentially a worldwide shared set of complex geo-applications. Any more, many concepts combining both GIS and Internet have been occurred, i.e. WebGIS, Internet-Based GIS, GIS Web mapping, etc. Nowadays, the application of the 3rd dimension in Internet-based GIS, with rare exceptions, is restricted and limited to research work.

Urban Mapping and Social Class
Author: Terra Wright

Does urban mapping allow city planners to structure cities based on social class? Many people believe that all communities offer the same types of business, such as grocery stores, specialty stores and restaurants no matter the income level in a city, the problem with this is, the statement is not true. In the city of Fayetteville, North Carolina, what is available in one part of the city is not offered in another, why is this? There are two different reasons that could determine why and how this happens, one the business’s are geared to make profits and require a certain type of consumer, and the other is what the needs of the community are. If you look at a particular area in the city of Fayetteville you will see upscale stores, restaurants , if you drive a mere twenty minutes you lose the stores and now are left with convenience marts, that sell a variety of items at a higher price to the people in the area. Is the structure of city and the business’s that are encompassed in it based on social class, profit or both? If you look in what is known as the impoverished part of the city, there are no grocery stores, the people have to rely on these convenience marts , that do not even sell healthy choices, these stores, often in high crime areas; offer cheap alcoholic beverages, processed foods and basic supplies. The restaurants in this area are fast food; there is no fine dining, no specialty stores, which means the choices for the people in the particular area limited. If you go back on the other side of town there is grocery stores, specialty stores, and nice sit down restaurants’, if you look at the people in that area, they have very affluent jobs, the income level and education tends to be higher. The question is , How can urban mapping restructure the city without putting social class limits and bring well rounded business’s to all the people in the city?

Com bin i ng science, art, and technol ogy, cartography offers effecti ve ways to represen t (or model) and com mu nicate geographic i n formation. Cartographic models such as poi nts, lines, and polygons are often used to represent the spatial features on the earth surface. With the advancement of mapping techniques such as GIS and geovisualization tools, it is possible to model the earth environment into a photorealistic, virtual reality in which a point feature to represent a building can be replaced by a vi rtual building. This paper discusses an approach to developing a photorealistic , virtual village located in Glen Carbon, Illi nois. Cartographic maps of the village are first generated , including features such as buildings , roads, cars, a power substation , overhead electrical power lines, a water tower, underground water mai ns, water sewer li nes, lawns, manholes , hydrants, and trees . Those cartographic features are then transformed into J D symbols to develop the virtual vi llage in which the user can explore and visual ize not only the JD scenes above the ground (e.g., buildings, hydrants, power li nes, trees) but also the JD scenes under the ground (e.g., water mains, sewer l ines). J n conjunction with the geometric network modeli ng, the user can experience the geometric networking among water tower, water mains, hydrants, and buildings (i.e., water flow). For example, the user can tum on the water supply from the water tower to see how the water flows in the water mains and into each building ; the user can also disable a T-val ve to turn off the water supply to a particular building . It is anticipated that such an innovative approach provides a new insight how spatial information about our environment can be effectively perceived through the use of photorealistic model i ng technique .

The studies of recent crustal movements are based on analyses of repeated geodetic measurements, and their combination with results of geophysical and geological investigations. It is obvious that a single data producer cannot produce useful datasets and information without integrating data from others because one scientist’s results become another’s data. So, the problem to be solved naturally has an interdisciplinary character. However, earth scientists traditionally work on one aspect of the problem and they have a tradition of sharing of data but they are willing to share it if asked.

The new generation of airborne laser scanners, the full-waveform LiDAR systems, are not only able to digitize but can record the entire backscattered signal of each emitted pulse, which provides the possibility of further analyzing the waveform and, thus, obtaining additional information about the reflecting object and its geometric and physical characteristics.

It is a trivial task for a five-year-old child to recognize and name an object such as a car, house, or building. However, it is a challenging process to identify and label these same objects automatically in a digital image. In the last three decades, researchers have used radiometric properties to identify objects in digital imagery. The supervised image classification algorithm groups similar image pixels based on their values. This approach has proven to be successful, yet it is reaching its theoretical limitation. For example, it is impossible to identify a car based only on color. A five-year-old child uses color, 3-D geometric shape, and other properties such as doors and wheels to identify a car.

Images provided by several imaging spectrometers are often contaminated with stripes. This artifact compromises the visual quality and radiometric integrity of measured data. Although a large number of destriping algorithms have been recently suggested, most of them provide results that display residual stripes if not strong distortion from the original signal. To overcome this issue, we introduce a robust methodology using a gradient-based iterative destriping algorithm (GBIDA). Statistical assumptions used in previous methods such as histogram matching are replaced with a more realistic geometrical consideration on the images spatial gradient. An iterative scheme is then used in order to isolate the striping effect from the original image prior to processing.

Airborne sensors provide a valuable source of imagery by virtue of the location of the deployed platform. However, obtaining precise and rapid information from such imagery has been difficult due to the enormous amount of post processing required by existing software and hardware to extract the geo-location for targets of interest.

Auto Hydro Break Line
Authors: George J. Toscano, Uday Kiran Gopalam, and Venkat Devarajan

In rural areas, hydro break lines are necessary to create LiDAR derivative products such as TINs, contours, DEMs etc. Water body detection and delineation are necessary to generate hydro break lines. Hydro flattening follows the detection and delineation of water bodies (lakes, rivers, ponds, reservoirs, streams etc.). Manual hydro break line generation is time consuming and expensive, especially when there are large number of lakes, rivers and their tributaries. Accuracy and processing time depend on the number of vertices marked for delineation of break lines. Automation with minimal human intervention is desired for this operation. In this paper, we proposed an advanced algorithm to detect water bodies automatically using both LiDAR elevation and intensity data. We used two distinguishing characteristics to detect water bodies. The first one is that the surface of water body is a flat area and the elevation of it is lower than that of the surrounding area. The second one is that spectral reflectance of water is very small in the near infra-red range compared with vegetation and other topographic features. Beyond these two broad strategies, we used additional techniques to fine tune the algorithm. After detecting water bodies, we generated 3D break lines. Finally, we performed a comparison of automatically generated break lines with their semi-automated/manual counterparts and we discussed the results.

Airborne hyperspectral ground mapping is being used in an ever-increasing extent for numerous applications in the military, geology and environmental fields. The different regions of the electromagnetic spectrum help produce information of differing nature. The visible, near-infrared and short-wave infrared radiation (400 nm to 2.5 μm) has been mostly used to analyze reflected solar light, while the mid-wave (3 to 5 μm) and long-wave (8 to 12 μm or thermal) infrared senses the self-emission of molecules directly, enabling the acquisition of data during night time.

The U.S. Geological Survey (USGS) has developed the first of a series of geometric test ranges over Sioux Falls, South Dakota. The purposes of these test ranges are for evaluating, validating and characterizing high resolution satellite and aerial images. The Sioux Falls test range uses accurate and standardized high resolution aerial orthophotos as a reference dataset to compare and characterize the geometric accuracy of satellite and aerial images. This paper first provides a report on the characteristics of the test range and the accuracy of the reference data. The paper goes on to show the use of automated image assessment methodology and results for the geometric assessment of GeoEye image using the reference imagery over the test range.

Integration of High-Resolution
Author: Yushin Ahn

Point cloud data from laser scanner has a complementary property to imagery data such as surface information vs. texture information. Advance in technology has reached to the point where a camera mounted on top of a laser scanner can assign color directly from image pixels to 3D point clouds. Current terrestrial laser scanning system with camera on board uses digital image pixel (color) retrieval and Orthophoto generation, but the scanner camera is not fully utilized in terms of 3-dimensional measurement. For example, a target that is more than 100 meters from the system tends to experience a degraded image, spatial resolution-wise, while generating a sufficient number of points. It simply means image resolution is fixed while laser-scanning parameters are adjustable through scan rate, scan angle etc. The objective of this study is to incorporate a high-resolution imaging system to the laser scanning system so that color information is updated from high-resolution image.

When looking at law enforcement and how they are able to be one step ahead of the criminals. What processes are being used? How are they able to understand spatial data and use GIS as a tool to stop or even prevent crime is a very important. Looking at the City of Fayetteville police department, the crime analysis department is using GIS to help the officers look for criminals, track crime statics and even prevent future crimes all with GIS. The officers understand that it is more than a map and the capabilities for them in their daily routines give them an advantage over the modern day criminal. Crime is just not about breaking and entering, murder and assault it is much more complex and being able to look at the different areas in the community to see the different crimes that are taking place is very important. By using GIS the officers are able to locate the criminals by the towers of the cell phone usage, also study the spatial patterns that might take place in a particular area and even map out a crime ring all by using GIS. This spatial tool is at the focus of meetings and how they are taking a spatial look at crime. When using maps in this type of process, the police are able to understand the nature of the crimes being committed and have evidence on what took place. GIS is the capturing, managing, analyzing and displaying information, this very system allows for criminals to be apprehend quicker, crime to be lowered and communities that have high levels or crime to have different programs in place to make the changes to stop these types of crimes from happen.

Different methods including various classification methods, principle component transform (PCT), band ratios, and a constrained energy minimization technique are evaluated for their performance for hydrothermal alteration zone mapping. First, these techniques are carried out to highlight known gold deposits over the Sukari Gold Mine. Then, the techniques are applied to different areas to search for sites that have similar spectral and other signatures in the processed images, with the idea that they may have conditions similar to those of the known gold deposits.

Building models are conventionally reconstructed by measuring their vertices point-by-point in a digital photogrammetric workstation (DPW), which is time and labor consuming process. Although aerial photos implicitly provide 3D information of buildings, LiDAR systems directly provide high density and accurate point cloud coordinates. However, LiDAR data cannot accurately represent the building boundaries. To take advantage of both systems, we propose Floating Model and a tailored least-squares model-data fitting (LSMDF) algorithm in this paper.

Assessing Variations
Authors: Tammy E. Parece, James B. Campbell, and David Carroll

Within urban areas, variations within the built environment create unique microclimates because of diversity in thermal properties of surface materials and alterations of the hydrologic cycle. Resolving intra-urban microclimate variability presents an opportunity to evaluate spatial dimensions of urban heat island effects, including daily air temperature fluctuations and local variations in start and end of growing seasons. Observations from National Weather Service (NWS) stations are often used to characterize regional conditions, yet such data are widely spaced and can only indicate conditions specific to that site. To effectively represent the fabric of temperature variations within an urban area, a finer network of data collection points is required. We report on a weather data collection campaign within Roanoke, Virginia using mobile weather units and weather stations newly installed at local public schools. We describe these data collection programs, outline methods developed for our collection pattern, and our preliminary analyses. We discuss our results and how they relate to the variation in Roanoke’s built environment. This research forms the first phase of dissertation research evaluating urban social and environmental patterns to facilitate optimal placement of urban agriculture. It provides the basis for understanding the spatial context for urban agriculture, and for ameliorating social and environmental difficulties inherent to modern urban systems. It fills a gap in current strategies, which largely have lacked spatial perspectives, and uses the power of geospatial technologies to identify relationships between the environmental and social dimensions of urban systems, and the spatial nature of their synergies.

Spatial Spectrum Analysis
Authors: Charles K. Toth, Zoltan Koppanyi, Dorota A. Grejner-Brzezinska, and Grzegorz Jóźków

Digital elevation models (DEM) are baseline geospatial products widely used in mapping and other applications. Generally obtained from airborne sensor data, DEMs can be made available at various spatial resolutions and accuracy levels. As DEM production costs vary significantly depending on the detail level of these two parameters, plans for data acquisition must be carefully balanced so as to satisfy spacing and accuracy requirements at the lowest possible cost. While most standard mapping techniques provide methods for determining the required resolution, they are usually based on qualitative surface definitions such as open, built-up and/or urban terrain, or by land cover such as weeds, crops, scrub, wooded, etc. These categories, however, are not necessarily correlated to the complexity of the surface, which ultimately defines the spatial sampling distance for any given surface representation requirements. This paper investigates a method for surface characterization that uses the spatial spectrum. Mathematically, DEMs can be modeled as real, single-valued functions of two variables. Using a 2D Fourier transform, surfaces can be represented in the spatial frequency domain, where each frequency can be interpreted as a different sampling rate of the measurements (i.e., spacing). In a simple interpretation: low-frequency components characterize slow changes of the surface, such as average slope, while high-frequency components describe the microstructure, or local, details. Evaluating representative DEMs, the most typical spatial spectra can be determined which, subsequently, can help practitioners define the optimal sampling distances and/or error requirements to determine DEM resolution and data acquisition for major surface categories.

3D city models have a wide range of applications such as mobile navigation, urban planning, telecommunication, and tourism. The generation of high resolution Digital Surface Models (DSMs), in particular from airborne LIDAR data have found a major attraction of researchers in this field due to their high accuracy and high density of points. In this paper, a new approach is proposed for the generation of 3D models of buildings that are extracted from a high resolution DSM. Particularly the complex buildings containing several smaller building parts are discussed. The building parts are individually modeled by a projection-based method and merged to form the final 3D model. The following building parts are considered to be modeled in the proposed approach: (1) flat roof, (2) gable roof, (3) hipped roof, and (4) mansard-shaped roof buildings. The complex buildings are decomposed into several parts according to the number of existing ridge lines.

Analysis of Epipolar
Authors: Zexun Geng and Baoming Zhang

Digital aerial frame cameras are widely used in mapping applications. As one most effective and frequently used constraint in digital photogrammetry research and practices, however, epipolar geometry relation of digital frame camera is not investigated deeply. In this paper, analytical transforming relation between center projective image (CPI) obtained by digital frame camera and epipolar image (EPI) is derived, based on which some fruitful result are revealed. The contributions of this paper are as follows. First the monotone mapping relation from CPI to EPI is obtained, which lays the foundation of two calibration algorithms in epipolar image generation. One is the fast indirect rectification per block algorithm; the other is direct rectification algorithm for any sub-region in CPI. Then a critical epipolar line is proved to be existed in CPI. The coordinates of epipolar point that all epipolar lines intersect at in CPI, are deduced thirdly. From that epipolar point, it is very easy to get slant epipolar line that goes through any image point in CPI.

Formats for Digital Elevation
Authors: Peter L. Guth and Filipe Vieira

The rise of handheld smart phones and tablets brings sufficient storage capacity and processing capabilities to perform significant terrain analysis on the local device. This work can be done as either native apps, or using the capabilities of HTML5. Digital elevation models (DEMs) come in a wide variety of formats, and it does not make sense for handheld device have translators for all of them. The handhelds need a simple format that compresses well, but retains accurate geospatial registration information. We created a JSON format with bzip2 compression, both of which have widespread support with JavaScript libraries. This format allows data only on the WGS84/NAD83 datum, in either geographic or UTM coordinates. A command line converter, based on MICRODEM supplemented with the GDAL libraries, performs DEM reprojection if necessary, converts to JSON format, and compresses for download to the handheld device. Lidar point clouds are now supplied almost exclusively in the LAS format. While the LAS format has a number of options, all include far too many fields for use on a handheld—for instance the 8 bytes for GPS time will not help someone in the field seeking to visualize terrain. We chose a similar JSON/bzip2 solution for MICRODEM to prepare point clouds, and achieve lossy compression roughly comparable to lossless LAZ compression. A GeoJSON format specification exists, but only applies to vector data. We propose GeoJSON-G for grids and GeoJSON-P for point clouds, which will retain full geospatial registration information while intelligently limiting the volume of data for the handheld devices to download and process. The handhelds will not edit modify the data, making elimination of unnecessary fields acceptable. We have adapted HTML5 and Javascript open source projects to display both DEMs and lidar point clouds.

Stereo Based Very High
Authors: Shabnam Jabari and Yun Zhang

Detection of urban objects in very high resolution (VHR) satellite imagery is challenging due to the similarities in the spectral and textural characteristics of urban land cover classes. Therefore, additional information such as elevation data is required for a proper classification. In this study, instead of LiDAR data, elevation information generated from satellite stereo images is used to assist the urban land cover classification in VHR imagery. RPCs are used to generate the elevation information. The classification process is performed using a fuzzy inference rule based system. This method is tested on GeoEye-1 and WorldView-2 satellite imagery. Preliminary results suggest that urban land cover classification is substantially improved by adopting elevation information from the stereo imagery, after it is transferred to the image domain.

On The Classification

A Synthetic Aperture Radar (SAR) system with hybrid-polarity architecture constitutes a significant advancement in the field of radar remote sensing. This new architecture system is a Compact Polarimetric (CP) SAR system which transmits a circular polarization and receives two mutually coherent orthogonal linear polarizations. This SAR system reduces some of the design constraints of the spaceborne satellite, allowing for a low-cost and low-mass SAR system. The main advantage of this SAR system is that it has a greater amount of information than the standard dual-pol mode, while covering the swath width of ScanSAR imagery. Therefore, a growing interest has been raised for CP SAR systems as a possible tradeoff in full quad-pol SAR systems. A CP SAR mode will be included in future SAR missions, such as the Canadian RADARSAT Constellation Mission (RCM) and the Japanese Advanced Land Observing Satellite-2 (ALOS-2). This paper is a first attempt towards the selection of the optimum CP parameters for sea ice classification. A set of twenty three CP parameters are assessed. A late-winter case study image is used, encompassing two sea ice types and one open water state.

Delineating Drainage
Authors: Tammy E. Parece and James B. Campbell

Urbanization alters the natural water cycle. One of urbanization’s most significant effects is increasing impervious surface cover which reduces infiltration, increases runoff volume and rate, and decreases evapotranspiration. Effective management of urban stormwater runoff and water quality issues can only be accomplished once drainage area and flow networks are accurately identified. Typically, geospatial evaluation of hydrologic impacts begins with identification of water flow and watershed boundaries, applying assessment techniques based on those designed for natural landscapes. However, urban hydrology differs from that of natural environments and thus urban watersheds require innovative evaluation techniques. This study identifies information gaps that originate from applications of standard geospatial techniques in urban hydrology. Delineation of a highly urbanized watershed in Fairfax County, Virginia was first accomplished using standard techniques. Next, using lidar data, the watershed was again delineated and both results compared. By overlaying both delineations on aerial photos and adding impervious surface and storm network layers, we identified regions redirecting the natural flow of water from the stream channel, then removed these regions from the watershed area. The results revealed a decrease in the watershed area by almost 17%, the natural watershed boundary was significantly altered, creating a much longer perimeter, and sink areas revealed. These results support the hypothesis that delineations of urban watersheds differ from those in natural settings. Anthropocentric alterations to land cover and landscape create a complex hydrology. The greatest complications are impervious surfaces and storm networks which redirect water flow.

Agricultral Land Use
Authors: Jie Ren, James B. Campbell, and Yang Shao

In central regions of the U. S. Corn Belt, agricultural production since 2001 has changed in response to federal policies implemented to encourage production of biofuels. As a result, increasing demand for sustainable bioenergy resources has accelerated biofuel production, and led to changes in agricultural land use. This study examines: (1) increases and decreases in cultivated area, and (2) pixel-by-pixel crop rotation sequences within a region of southeastern Iowa. The practice of agriculture brings lands in and out of production in response to variations in local landscapes, markets, and technologies. Further, crops are rotated in response to environmental and market concerns. Knowledge of how such lands are used, and of their topographic and pedological properties, forms a prerequisite for understanding the context for developing sustainable management practices and policies. This study examines temporal and spatial patterns of agricultural land use from 2001 to 2012 in a region of southeastern Iowa within a single Landsat scene (Path 25/Row 31). After 2007, intensity of cultivated land use increased and crop rotation changed from standard corn-soybean or soybean-corn cycle to more intensive rotations. These changes may be correlated with market forces. Intensity of cultivated land use depended on topographic and pedological properties, although motivations and constraints perceived by farmers and managers as they plan their use of landscapes are important.

Feature-based matching is commonly employed for object surface reconstruction in topographic and stereo close-range photogrammetry, but rarely in conjunction with convergent photogrammetric networks. This paper describes a new feature-based matching approach to automated 3D object reconstruction from highly convergent, multi-image networks. Geometric diversity and redundancy in the network design are a distinct advantage with the approach, which commences with automatic exterior orientation. The FAST interest operator is then applied to Wallis-filtered images to extract interest points, and matching of interest points is carried out to yield a dense 3D point cloud. The surface point data is subsequently converted to a triangulated mesh via a Poisson Surface Reconstruction technique, and textured.

The Coastal Watershed in New Hampshire is an area covering 990 square miles of varied habitat, from areas that are well developed, to large tidal bays and managed forests. The watershed is also home to around 155 species of rare plants, 18 rare species of animals, and 35 different rare natural communities and ecosystems. However, due to pressure from rapid development, fragmentation, invasive species, water quality degradation, and climate change, many of these habitats are disappearing faster than ever.

Land use/cover changes (LUCC) are significant to a range of issues central to the study of global environmental change. Over the last decades, a variety of models of LUCC have been developed to predict the location and patterns of land use/cover dynamics. The simulation procedures of most computational LUCC models can be sub-divided into three basic steps, 1) a non-spatial procedure which calculates the quantity of each transition, 2) a spatial procedure which allocates changes to the more likely locations and eventually replicates the patterns of the landscape and, 3) an evaluation procedure which compares a simulated land use/cover map with the true map of the same date.

Despite the plethora of data-acquisition programs collecting remotely sensed high-resolution imagery in the United States, few corresponding high-resolution statewide land-cover datasets have been developed. This is understandable given the challenges inherent in extracting information from massive, highly-variable datasets encompassing heterogeneous landscapes. To overcome these challenges during development of a statewide, high-resolution tree-canopy dataset for Maryland, USA, we designed and deployed a rule-based expert system for mapping land-cover features from multispectral imagery and LiDAR. This object-based approach facilitated integration of imagery and LiDAR into a single classification workflow, exploiting the spectral, height, spatial information contained in the datasets. Rule-based expert systems provided an intelligent approach to feature extraction, ensuring consistency in the output despite variability in collection parameters, data quality, and data completeness, among others. Finally, by distributing the processing load to multiple computing cores, we efficiently extracted land cover from remotely-sensed datasets constituting terrabytes of digital data, covering the entirety of Maryland’s 25,640 km2 (9,900 mi2) land area. We conclude that an object-based approach that incorporates expert systems and enterprise processing is a cost-effective method for statewide land-cover mapping.

Given their location in the intertidal zone, coastal salt marshes will be one of the ecosystems first affected by sea level rise. As sea level rise increases, marshes will begin to migrate inland if surrounding topography and land use provide suitable habitat. The question remains whether or not this migration inland will provide enough new habitat to sustain current marsh area as the seaward edge of the marsh begins to become permanently inundated. This project created an ArcGIS tool using Python computer language that projects future salt marsh habitat under a variety of sea level rise and land use scenarios.

Understanding that various tree species have characteristics similar to each other, it follows that some type of hierarchical classification scheme could be used to identify species using LIDAR data. Cluster analysis, one of the unsupervised classification methods, was conducted for all individual trees using the k-medoid algorithm. Instead of using one-step cluster analysis, a stepwise cluster analysis was developed based on the statistical criteria to test hierarchical relationships between species. Two seasonal LIDAR datasets collected at the Washington Park Arboretum in Seattle, Washington were used for this study.

Current tree species classification algorithms often use high-resolution satellite data and are in many cases based on forest stands. The spectral bands of the sensors used for data acquisition are given and cannot be chosen regarding the needs of tree species classification. Furthermore distinction is often limited to deciduous trees, coniferous trees and other land use classes.

Many people use a commercial image database such as Google Earth Image map from the internet. We propose a method by volumetric shadow analysis for generation of 3D building models from the commercial image database. The proposed method can extract building heights and building footprints using volumetric shadows analysis from a single image. No external control points are required. Instead, the proposed method needs the directions of the sun and the camera is needed.

An optimal linear translation and attitude estimation (OLTAE) algorithm is proposed to register 3dimensional point clouds based on the image features associated with the individual data sets. In LIDAR applications, such images are created by projecting the point cloud data on to an image plane. Physically, this image is the return light intensity observed by the LIDAR imager that is usually available to the analyst for post processing. Associated image features are extracted from the corresponding images by utilizing the recent advances in computational vision and image processing. Features thus obtained have unique descriptors that automate the matching process and ease the solution of the so-called correspondence problem.

Human activities have transformed at least one-third of the Earth’s surface in the past century, and land-cover and land-use analyses play a critical role in human-environment interaction analysis. Land-use analysis, especially for residential land uses, is comparably more challenging than land cover as land use categories relate less directly to the physical reflectance obtained by remote sensors; however, land-use classification recently attracts a growing attention because of the advancement in high-resolution imagery and the demand to improve intra-urban structure mapping.

A method for abstracting a 3D model by shrinking a triangular mesh, defined upon a best fitting ellipsoid surrounding the model, onto the model's surface has been previously described. This "shrinkwrap" process enables a semi-regular mesh to be defined upon an object's surface. This creates a useful data structure for conducting remote sensing simulations and image processing. However, using a best fitting ellipsoid having a graticule-based tessellation to seed the shrinkwrap process suffers from a mesh which is too dense at the poles.

The paper reports about investigations into the utilization of the SIFT algorithm to support image matching between different image domains. The Scale-Invariant Feature Transformation, proposed by Lowe in 1999, is a highly robust technique that has been widely used in the computer vision community. Though, SIFT is known in mapping circles, so far its use is rather limited. The objective of our study is to assess the performance of SIFT when it is applied to imagery acquired by different sensors and on different platforms. For testing, four image datasets from different sensors were considered, including airborne and satellite imagery, and LiDAR intensity and elevation.

Estimating Rainfall for
Authors: Arif Albayrak, William Teng

Index-based agricultural insurance is a promising alternative for individual farmers who cannot afford traditional insurance based on field inspections for assessing losses. Weather-indexed agricultural insurance, with payouts tied to pre-determined triggers of local indices, requires no field visits, thus significantly reducing costs. To be effective, weather indices need a sufficiently dense network of quality-controlled weather stations. However, in some regions of the world, the number of stations is often limited and located in the main cities and not near farms that are to be insured. Our study focused on estimating rainfall for areas without rain gauges. For the first phase, we assumed there were no available data from the particular farm to be insured. To obtain daily rainfall estimations for that farm, we applied the neural networks method to interpolate/discover rainfall data, using information from neighboring stations. For the second phase, we assumed there were some limited data available from the farm. To test our method, we used 10 years of rainfall data collected from 21 land-based stations in Iowa, U.S. We started with a small number of stations and systematically increased that number and, thus, the information content of the entire system. Overall, this study showed an improvement in rainfall estimation, when information content from station data increased. While promising for application to weather-indexed agricultural insurance in some areas, the method used in this study could not help extend insurance coverage to areas too far away from existing stations. Thus, the next step would be to incorporate satellite data to increase the density of rainfall and other measurements. The upcoming Global Precipitation Measurement (GPM) and Soil Moisture Active Passive (SMAP) missions (2014 launches) will extend the current data records for both measurements into the future, as well as provide improved quality and resolution.

Multi-Sensory Data Integration
Authors: Abdulla Al-Rawabdeh, Ayman Habib, Fangning He

Geotechnical engineering is a relatively new discipline that has developed rapidly over the past 30 years. It deals with a wide spectrum of natural geological materials ranging from low strength soils to high strength rocks. Earth movements are common in many parts of the world and, as a result, present serious safety and mortality risk to humans in addition to affecting construction activities. Earth movement can be classified into different categories with landslides as being one of those categories. In order to assess the stability of landslides, different geo-technical parameters are required such as the strike and dip of the discontinuity planes in the potential area. Areas affected by landslides are often inaccessible which makes manual compass and inclinometer measurements challenging because of the danger involved in this operation. Preventing large natural landslides is difficult; however some mitigation is possible and can help to minimize the hazards. Nowadays, 3D modeling of objects can be achieved through either passive or active remote sensing systems. Active sensors, such as Terrestrial Laser Scanning systems (TLS) have been used extensively for quick acquisition of highly accurate three-dimensional point cloud data with high resolution. However, the TLS in some cases has limitations during the data collection due to occlusions, orientation bias and truncation. This research addresses those issues by investigating the possibility of augmenting TLS in the occluded regions through close-range photogrammetry to generate high resolution and dense point cloud using the Semi-Global Matching (SGM) algorithm. By augmenting the two data acquisition methods and registering to a common coordinate system to provide a complete point cloud for the area of interest, any limitations and exposed gaps in the data are filled. Planar segmentation is then carried out to extract the required geotechnical parameters automatically. Four sets of geotechnical parameters have been compared in this research: 1) a set of manual measurements, 2) a set extracted from the TLS data only, 3) a set extracted from the SGM algorithm only, 4) and finally a set extracted from the fused TLS and SGM data. The results showed that the data fusion method provided more accurate results when compared to the results coming from the TLS data and those coming from SGM only. This reveals that the impact of the occluded regions on the calculations of the geotechnical parameters must be considered to achieve the required quality of the estimation process. The proposed method of this research provided high quality measurements for the geotechnical parameters required to assess the landslide hazard, ensured safety, and saved cost and time.

This paper describes a semi-automated process developed to extract and merge raw, geospatial feature data from multiple sites on the Internet. This process was tested on varied set of feature classes (specifically airfields, golf courses, maritime lights, police stations, and post offices of South Africa) to evaluate the effectiveness of the procedures. As an illustration, the results for airfield processing are presented. During processing of raw disparate data captured on the Web, attributes were aligned, duplicate records were eliminated, record-level metadata was preserved, and unit of measure conversions were performed. The processed raw data is then merged into a single dataset and attributes are integrated and duplicates are again eliminated. The final quality control review includes a final record-by-record imagery review of all candidate features to insure they actually exist on the ground, their geo-coordinates are accurate and that all duplicate instances have been eliminated. It has been found that this process is faster than the traditional wide-area search technique used to populate and maintain feature databases. The process also provides significant increase in location accuracy and increased feature counts relative to heritage data sources used in the study.

Building Detection in
Authors: Shabnam Jabari and Yun Zhang

Detection of buildings in urban and suburban areas using very high resolution satellite (VHR) images is a challenging task due to different illuminations on different sides of the same building roof. This causes different brightness values on a single roof. Therefore, in the segmentation step of an object-based classification, different sides of a roof will be assigned to different segments due to their intensity variation. To solve this problem, the majority of the studies merge the building roof segments together based on elevation information. However, because of the uncertainty of the borders in elevation layers as well as misregistration between the spectral and elevation layers, building boundaries usually cannot be detected precisely. In this study a novel method which utilizes IHS color transform is used to overcome the problem of intensity variation to segment each building roof as one segment. Then, the elevation information from LiDAR data is used to differentiate roof segments from other segments. The proposed method is tested on the QuickBird satellite imagery of Fredericton, Canada. The achieved results are quite promising with an overall accuracy of more than 90% for building detection. Considering the off-nadir situation of imagery and consequently miss-registration between the elevation data and the image, the produced unified color segments are of great benefit for precise building boundary detection.

NASA’s earth observation missions commenced with the Television Infrared Observation Satellite (TIROS) series in the 1960s and continued with the Nimbus and Landsat satellite missions beginning in the 1960s. The Nimbus satellites inaugurated multi-sensor missions for environmental remote sensing. In the ensuing four decades, NASA’s Earth science activities have led to increasingly sophisticated satellite instruments, much larger data volumes, more complex data analyses, and a diverse suite of data products generated with sophisticated data algorithms. NASA now has at its disposal a huge amount of information about the state of our planet obtained from the vantage point of polar and low earth orbit satellites. For scientists seeking to study Earth’s changing climate, having long-term time series of data on key climate variables is crucial. The data from these missions constitute a vital archive for Earth science research.

Nationwide Flood Inundation
Authors: Youngjoo Kwak and Yoichi Iwami

Near-real-time flood flood mapping is one of the most important parts of emergency response efforts. This paper aims to estimate extreme flood inundation area over the entire Bangladesh, where monsoon river floods are dominant and frequent, affecting over 80% of the total population. The authors improved a water-extent extraction method for a better discrimination capacity to discern flood areas from cloud and mixed areas by using a modified land surface water index (MLSWI) based on the Moderate Resolution Imaging Spectrometer (MODIS) 8-day composites (approx. 500m resolution) data. Flood areas in the Brahmaputra River were verified by comparing them with ALOS AVNIR2 (approx. 10m resolution) data. The results showed the superiority of the developed method in providing instant and accurate nationwide mapping of floodwater extent in the three main rivers for the 2007 extreme event in the Bangladesh.

Cloud GIS based services, large scale DEM GIS datasets, and onboard mobile device graphic and sensor resources allow creation of a functional terrain viewshed least observed path (LOP) geovisualization mobile application. The LOP application enables a mobile device user to visualize the best path to travel, from their current location to a point visible through their device’s camera, minimizing the possibility of being seen from one or more application identified observer points. The application consumes cloud generated terrain viewsheds, for the identified observer points, combines the viewsheds locally and constructs an augmented reality color scaled geolayer. The application’s dashboard viewer overlays the generated geolayer on the devices live camera feed to provide the LOP view. The LOP view updates as the mobile user’s location changes and traverses observer point viewsheds. The LOP Android application implemented several critical technical decisions. Sensor orchestration algorithms manage GPS, accelerometer, gyroscope and device orientation input to synchronize the LOP geolayer with the live camera feed. Key system elements supporting the application include services and data hosted by a cloud GIS. Utilizing cloud based services significantly reduces computational times to perform viewshed terrain analysis for identified observer points. The cloud also provides large scale storage of DEM datasets providing a geospatially wide operational domain. Field tests of the LOP application utilized SRTM 3 arc-second, ASTER GDEM 1 arc-second, NED 1/3 and 1/9 arc-second, and 1 meter lidar first return. Initial performance results indicate DEM data source resolution has negligible impact on computational processing times on the cloud and mobile platforms but LOP results vary based on DEM data sources in urban landscape The LOP results and user experience can be improved by considering nearest neighbor results when calculating the LOP geolayer.

A New Automated Aerotriangulation
Author: Frank L. Scarpace

Image Processing Software, Inc. has developed a new easy-to-use automated aerotriangulation product called IPS-Match™. The product will automatically find conjugate points in overlapping areas of images and uses a very fast bundle adjustment to determine the exterior orientation of the images. Poor matches are automatically eliminated resulting in RMS residuals from the bundle adjustment ranging from 0.3 to 0.5 pixels. The results of the bundle adjustment can be graphically displayed so the user can assess the strength of the solution. Project setup is made easy, using a setup Wizard that guides the user through the setup process. Existing orthophotos can be used to allow easier project setup and also as a substitute for ground control for historical film applications. IPS-Match™ currently also creates orthophotos and orthophoto mosaics of the project imagery. The program works with or without GPS/INS as well as with film or digital cameras. Fiducial marks are automatically measured for file imagery. IPS-Match™ works well with any number of images, only limited by storage and/or computer memory. The program can generate vertical oriented images which are ideal for stereo interpretation. The next version of IPS-Match™ will include the generation of Digital Elevation Maps. This product is specifically designed for the small to medium sized digital camera photogrammetric projects, but will work equally well with traditional film based camera projects. The unique features of IPS-Match™ allow it to be a cost effective tool for use in historical film applications, emerging UAV applications, and traditional photogrammetric applications.

Land Cover Classification
Authors: Haile K. Tadesse and Allan Falconer

Radar and Landsat data were used to classify land cover in north central Ethiopia. Both images were registered and resampled to 12.5 m spatial resolution. Maximum Likelihood Classifier (MLC) and C4.5 algorithm were applied. The original radar data produced low overall classification accuracy (66%). To improve this classification accuracy, de-speckling and texture measures were used for image enhancements. The de-speckling methods used in this study are Median, Lee-Sigma and Gamma-MAP. Lee-sigma, Gamma-MAP and Median de-speckling improved the overall accuracy by 15, 18 and 20% respectively. The maximum overall accuracy achieved in this study by de-speckling method is 86.4% using Median at 27*27. Urban producer accuracy improved by 58% by using Median de-speckling. All de-speckling techniques improved urban user accuracy to more than 90%. In most de-speckling cases, MLC outperformed C4.5 classifier in the overall classification accuracy. The highest overall accuracies achieved by texture are 88.8 and 90.5% when MLC and C4.5 algorithms at window size 51*51 were used respectively. This shows 22% improvement compared to the original radar data. Urban and forest producer accuracy improved by 58 and 26% respectively at window size 43*43. The overall classification accuracy of Landsat data is 93.7%. Combining Landsat and derived radar data measures improved land cover accuracy by about 5%. This study showed the importance of texture and de-speckling techniques to improve a land cover classification in radar data. Therefore, radar data can be used as an alternative to optical data in the tropics and Ethiopia for land cover classification.

Paper describes a methodology to improve classification of urban features by using object oriented classification techniques. Mapping urban features from satellite data is challenging due to several reasons. Urban objects are spectrally similar and they have different shapes, sizes, patterns, all of which contribute to their low accuracy. For example, features such as roofs, roads, and other spectrally similar objects like open space (concrete) appear spectrally similar leading to their low accuracy in classification. Very high resolution satellite data (Ikonos) was classified using both supervised and object oriented classification techniques. A combination of spectral, spatial attributes and membership functions were employed for mapping urban features.

The difficulty of identifying conjugate points between both datasets is overcome by the derivation of automatic features extraction. Hence, the extracted features from the terrestrial measurements represent a good candidate for co-registration. Field work is performed to validate the proposed methods.

Automated Target-Free
Authors: Clive S. Fraser and Christos Stamatopoulos

Automatic camera calibration is now a well-established procedure. The process generally involves photographing a target array to form a network of images in a geometric configuration suited to self-calibration. Full automation can be implemented if coded targets are employed, as these provide initial image point correspondences necessary for network exterior orientation. While the use of coded and indeed any artificial targeting facilitates high accuracy recovery of camera calibration parameters, it is also fair to say that the employment of targets can be inconvenient in some practical circumstances, for example when attempting calibration from low-level aerial imagery, as with UAVs, or when calibrating long-focal length lenses where small image scales call for inconveniently large coded targets. Fortunately, accompanying the adoption of so-called structure-from-motion (SfM) approaches in photogrammetric network orientation, there is the prospect of fully automated camera calibration without the need for artificial targets. Instead of the image-point correspondence problem being overcome through the use of coded targets, feature-based matching is employed to provide the necessary point matches to support exterior orientation. Whereas it is not uncommon to achieve an accuracy of camera calibration of 0.1 pixel or better through the use of coded targets, the resolution from the feature-based matching process is generally closer to 0.3 pixel. This difference is offset, however, by the fact that whereas 100 or so targets might be employed, the SfM approach can easily involve 10,000 or more feature points on a feature-rich object, thus leading to a very comprehensive calibration result. This paper reports on the application of the SfM approach to automated target-free camera self-calibration and discusses the process via practical examples.

Initially, remote sensing methodologies, along with other geo-spatial techniques, were employed for monitoring restoration progress in the Indian River Lagoon (IRL) watershed by the Saint Johns River Water Management District (SJRWMD). These methods were also used in identifying critical habitats in the Guana-Tolomato-Matanzas National Estuarine Research Reserve (GTMNERR). Using no-cost, publicly available digital airborne Color Infrared (CIR) imagery, progress was measured for the restored wetlands in Mosquito River Lagoon of the IRL system. Normalized Difference Vegetation Index (NDVI) was the technique employed. Next, an experiment was conducted to map and isolate the Northern most extent of mangroves (dominated by black mangrove – Avicennia germinans) among the emergent intertidal vegetation within the GTMNERR. DigitalGlobe’s WorldView-2 (WV-2) imagery was used along with ground-truthed and LiDAR data. In conclusion, this study demonstrated that high resolution multiband (~8-bands) satellite imagery collected at phenologically correct time at low-tide has the potential to quantify the spatial dynamics of this habitat to study the effects of long-term climate change over a period of time.

In this paper we introduce an approach for quality inspection based on map matching and data integration. Two datasets are the input for the process. At first, the edges of the datasets are matched manually. Then, the form of each matching pair is determined and corresponding nodes are matched. In the final step, quality measurements on different levels of granularity are calculated. On the dataset level, a global geometric quality measure based on the evaluation of adjacency matrices is proposed. Furthermore, completeness and topologic similarity are measured. On the matching pair level, geometric modeling, geometric similarity and attribute similarity are analyzed.

While ground sampling distance has been misleadingly used as the most popular measure of image quality among image providers, satellite manufacturers and general public, user community may be keen to the interpretability of remotely sensed imagery. As one measure of image interpretability, the NIIRS (National Imagery Interpretability Rating Scale) has been used. Currently, this measure is included in the metadata of some high resolution satellite images. Traditionally, the NIIRS is estimated by deploying specially made tarps of uniform reflectance. Due to this, estimating NIIRS is costly and not carried out often.

High Accuracy Pavement
Author: Michael Loose

The increasing commercial use of Mobile Mapping LiDAR Technology, especially for transportation applications, is revolutionizing the way that pavement elevations are captured. However, existing technologies such as low altitude mapping photography (LAMP) or helicopter based photogrammetry are still used largely because of their proven accuracies and known cost factors over many years of use. Mobile LiDAR has the potential to increase accuracy, improve speed in project delivery and reduce costs for data collection. To test the feasibility of replacing LAMP based photogrammetry, PennDOT’s Photogrammetry and Surveys Section, along with engineering District 4-0, are working (at the time of this abstract submission) to compare mapping data collected by traditional LAMP methods and data compiled from mobile LiDAR. The area chosen was a six mile section of Interstate 84 in Pike County, Pennsylvania. Mobile LiDAR data was captured with an Optech Lynx M1 Mobile Mapping System (MMS) owned and operated by Photo Science, a Quantum Spatial Company, LAMP photography was flown at a negative scale of 1:600 (300 feet AMT) by Richard Crouse, Inc both companies were under contract with PennDOT. Ground truthing will be done by survey grade GPS combined with field differential leveling to provide a minimum of 40 test points that will be used to access and compare the horizontal and vertical accuracies of both data sets. Time and cost comparisons will also be documented.

Sigma-Trees associated with residual vector quantization (RVQ) has been used for image-driven data mining to detect features and objects in a digital image with a degree of success. RVQ methods based on σ-tree structures have been designed to implement successive refinement of information for image segmentation. In such implementations, RVQ based novel methods are devised for pixel-block mining, pattern similarity scoring, class label assignments and attribute mining (Barnes, 2007a). Direct sum σ-tree structures are used for near-neighbor similarity scoring. The variable bit-plane data representations produced by σ-tree structures not only provides an approach for image content segmentation and a structure for formulation of Bayesian classification, but also offers a solution to the challenge of high computational costs involved in pixel-block similarity searching.

Orthophoto map, ortho-rectified image, constitutes a central component of the mapping and GIS activities in general and of photogrammetric mapping products in particular. Technological developments of recent decades lead to the ability to produce color digital orthophotos from aerial and satellite imagery. As the source imagery acquired by the sensors are of high quality and density, radio metrical quality of the orthophoto products is dependent on the ability to perform a high quality sampling of the colors from the original image into the target ortho-rectified image.

Interest points on the building façade are the basic element for 3-D building modeling and texturing. Grouping these points to the same or separate buildings is a fundamental process for establishing building models and detecting building boundaries. The grouping process is generally achieved by analyzing the geometric relation and the distances between the points in the object space, which requires precise interior and exterior orientation camera parameters.

Geopositioning from optical sensors onboard airborne platforms, e.g. UAVs, requires a sensor model and subsequently a means to perform rigorous covariance propagation of position and attitude parameters to the ground space. Builders of such imaging systems often do not know precisely what elements to report, and how to report them, in the data stream along with the image pixel data. As such, it is mutually beneficial – to both builders of an imaging system and to exploiters of the imagery – to define a minimum set of metadata elements, including associated covariance information, which shall be populated with values.

Over the last decade, terrestrial laser scanner systems have been proven to be an effective tool for the acquisition of 3D spatial information over physical surfaces. Many factors such as the low cost and the ability of rapidly collecting dense and accurate spatial data led to the utilization of laser scanners in different applications such as industrial sites modeling, 3D documentation of buildings, and many civilian and military needs. Usually, a complete 3D model for a given site cannot be derived from a single scan. Therefore, several scans with significant overlap are needed to cover the entire site and also to attain better information about the site than what could be obtained from a single scan. However, the collected scans will be referenced to different local frames that are associated with the individual scanner locations. Hence, a registration process, which aims at estimating the 3D-Helmert transformation parameters, should be established to realign the different scans to a common reference frame. This paper introduces a new methodology for the automatic registration of terrestrial laser scans using linear features. Linear, cylindrical, and pole-like features are directly extracted from the scans through a region-growing procedure. Hypothesized conjugates of linear features are identified using invariant separation characteristics such as spatial separation and angular deviation between two linear features. All the hypothesized conjugate pairs – taken one at a time – are used to estimate the 3D-Helmert transformation parameters that are required to realign one scan to the reference coordinate system of another scan. Logically, only the right conjugate pairs among the hypothesized matches will lead to similar solutions of the transformation parameters. Therefore, we developed a strategy to detect the most frequent set of estimated parameters. A linear mathematical model that utilizes quaternions to represent rotation angles is used to simplify the estimation of the transformation parameters. Experiments will assess the performance of the proposed methodology over multiple scans of a power plant.

Urban Mapping in Fayetteville
Author: Tisha Jolene Jahangir

Urban mapping is a type of visual graphic presentation of concepts, conditions or processes. In the cities one may use urban mapping when it comes to how and where businesses are located. People think that businesses are just in a particular location, without understanding the whole planning process. The question is who decides where and what types of businesses go where, or does income and status play a role in urban planning. If you were to look at the city of Fayetteville, North Carolina, you would see a vast difference in the neighborhood businesses, they can range from high end stores, and to the low end convenience stores that sells grocery store items at a higher price to the community. How can urban mapping restructure the different communities and make all of the same business available to everyone? As the city planner, understanding the needs of the community and the needs of the business’s owners to make a profit would have to be taken into consideration. One view point would be to have the city planners make the decision on what type of business should go in certain areas, this way it would create uniformity across the city and allow people to shop at the same types of business regardless of where they live. On the other hand, the businesses would still have to make a profit and carting to all types of people in the city might not have their best interest in mind. How can urban mapping are used to create a uniform city and look at the different demographics, which would allow for a variety of business to be in the city, without looking a wealth and status as a factor.

Small-size and low-cost imaging sensors, which are widely used in a multitude of consumer devices, provide medium-quality, typically redundant data that has the potential to be used for mapping and navigation purposes. For example, the Microsoft Kinect™ contains both passive and active imaging sensors, significantly extending the range of possibilities in its application. This study is focused on the indoor mobile use of the Kinect™ sensor for mapping and navigation. Mobile mapping of the indoor environment in 3D using Kinect™ may be realized by stitching the point cloud series acquired during movement and then reconstructing the navigation trajectory. In this study, a combined point cloud registration method is proposed that is based on 3D transformation of consecutive point clouds with transformation parameters estimated on the basis of matching 3D points. Since the modest geometrical quality of Kinect™ point clouds causes difficulties for finding corresponding 3D points, the matching was primarily performed on RGB images (2D) by applying the SIFT method. Knowing the relative orientation between Kinect™ passive and active sensors, each SIFT key-point can be associated with points in the 3D depth image and, consequently, with a 3D position. Results of several tests in a typical indoor corridor environment showed that the proposed approach for stitching point clouds allows for robust reconstruction of the trajectory and, in general, easy combination of numbers of Kinect™ image frames. Similar to other navigation systems based on image sensors alone, the Kinect™ image data also has some limitations, which are discussed in this paper.

High-resolution digital elevation models (DEMs) created from small-footprint airborne Light Detection and Ranging (LIDAR) scanning system data contain information that can reveal micro-terrain features and their spatial patterns, especially in the absence of dense forest overstory. We applied numerical techniques to a bare-earth gridded LIDAR DEM of a region containing both coniferous canopy and open rugged terrain to calculate directed second derivatives for each matrix location by fitting cubic splines to the data. Thresholding the results allowed the creation of spatially correlated layers of (1) micro-terrain features identified by rapid slope change and (2) associated azimuthal directions of maximum slope change. Canopy layers were created from first and last return LIDAR grids using a thresholded differencing algorithm.

Automatic derivation of land cover information from optical satellite data is one of the main research topics in remote sensing. Accurate land cover products are needed for biogeochemical modelling and biodiversity analysis. Land transformation processes are analyzed in the framework of global change studies. While many global land cover products fulfil the needs for driving global models, their accuracy is insufficient for regional to continental applications. The North American Land Change Monitoring System is a tri-national initiative to provide accurate, automatically generated annual land cover and land change products. Its first product, the land cover map of North America for 2005, has recently been completed and is published by the intergovernmental Commission for Environmental Cooperation.

Airborne oblique images are increasingly acquired because of the availability of low cost sensor platforms, being equipped with multiple camera systems. These images are mainly used for visualization such as the Bird’s eye in Microsoft’s Bing Maps. Because of their characteristics, such as a varying scale and the need for combining several images for complete information of all sides of a 3D object, oblique images are up to now only seldomly used for automatic topographic data acquisition and update. However, side views allow better identification of imaged objects and may be useful for verification of building datasets.

Automatic Orientation
Authors: Fangning He, Ph.D. and Ayman Habib

In this paper, we present an automatic algorithm to estimate the orientation of multiple images with respect to terrestrial laser data. The proposed algorithm takes advantage of both conventional single-view and multi-view registration approaches. The algorithm consists of three steps. In the first step, intensity images are generated from the terrestrial laser data with intensity information, and the initial exterior orientation parameters (EOPs) of each camera image are then estimated from feature correspondences with the intensity images. In the second step, the initial EOPs obtained from previous step are refined through a bundle adjustment process. In the third step, the point cloud reconstructed from the bundle adjustment process is registered to the terrestrial laser point cloud to determine the final orientation of each image. The proposed algorithm is tested on experimental datasets, and the results demonstrate that the proposed algorithm can efficiently handle the orientation estimation of multiple images with respect to the terrestrial laser data.

Improving Techniques
Author: Andrew Johnston

Urban forests are a central element of the urban environment. Improved observations of historic tree cover dynamics are required to better understand how the urban environment changes though time. In this study, satellite remote sensing techniques were applied to observe past variability in tree cover area within the District of Columbia using highly calibrated Landsat data. Validation was performed with data from field surveys and public geospatial data on standing tree cover. Testing of alternate methodologies demonstrated that an approach utilizing support vector regression produced results with greater accuracy across the city when compared to linear spectral mixture analysis. Per-pixel uncertainty remained high using both techniques. Spectral mixture analysis overestimated tree cover in low population density areas and underestimated tree cover in the urban core, while support vector regression provided consistent accuracy across land use types. The consistent reliability allowed results from support vector regression to be used for observing tree cover changes between different land use zones. This will make it possible to identify past tree cover changes in low density residential zones within the District of Columbia. These results provide useful background information for maintenance and resource management as part of efforts to monitor and expand urban tree cover. Further development of these methods may enable their application with archival moderate resolution satellite remote sensing data for other study areas.

Site Selection for Base
Author: Mert Marangoz

In mobile telecommunication systems (GSM/2G, EDGE/2.5G, UMTS/3G, LTE/4G ...), the planning of the location of the base station is key for uninterrupted communication. The major problem in achieving ideal signaling between mobile phones and base stations is inaccurate site selection due to the altitude of the region. In addition to altitude, there are many important parameters such as height of buildings and population density. If site selection is inaccurate and determined without reference to any previous parameters, the connection between mobile phones and base stations can be often interrupted and calls can drop. If old or new communication technologies have lots of problems such as inaccurate site selection, these should be fixed and regularly checked by optimization engineers. When a new technology is developed, firstly it should be applied to a trial area. After a period of study, results will indicate its suitability. After the region is determined, the next stage is determination of base station location depending on legal and expert opinion and carried out with site selection tools. When calculations are made to determine site locations, radio wave propagation (Okumura-Hata, Erceg-Greenstein, SUI, etc…) should be simulated using by RF tools to make a coverage map. In this study we created a site selection tool to select sites before calculating the LTE coverage map in built up area for the Beykoz district of Istanbul.

A Probabilistic Approach
Authors: Omar E. Mora, Charles K. Toth, and Dorota A. Grejner-Brzezinska.

A probabilistic approach is proposed to aid landslide susceptibility mapping. The objective of the proposed approach is to identify and predict areas that may develop into landslides and quantify the growth of existing landslides with high probability. Change detection was applied to repeat airborne Light Detection and Ranging (LiDAR) surveys acquired in December of 2008 and April of 2012. The study area was along the transportation corridor of Muskingum State Route 666 in Zanesville, Ohio, an area characterized by high vegetation densities, stream and river channeling, and some residential development. In the investigation, changes between LiDAR-derived Digital Elevation Models (DEM) were computed by analyzing, cell-by-cell, the vertical differences and, consequently, generating a DEM of Difference (DoD) map. Then, a parametric z-test was used to evaluate probabilistically if single-cell differences were real as compared to noise. Next, a non-parametric signed rank test was used to assess local neighborhoods and compute the probability that the median of the samples surpassed a desired threshold. Finally, high-probability neighborhoods (clusters) comprised of a minimum area and desired probabilities were mapped as “landslide susceptible”. The initial results, obtained by comparison to a reference landslide map, were as expected, indicating that segments of the mapped landslides experienced changes, while others did not. It was also observed that some unmapped areas also experienced changes, indicating that they may be developing landslides. This study demonstrates that the monitoring of existing and identification of newly developing landslides is feasible from multi-temporal airborne LiDAR data.

Leica XPro 4.0 for processing ADS imagery has introduced new radiometric correction models to reduce image bias created by atmospheric and ground reflections. Most notable is the availability of atmospheric corrections based on the equation of radiative transfer and a correction that deals with bidirectional reflectance effects on the ground (BRDF) based on a modified Walthall model. To obtain best results, it has been proven that land body masks determined by classification of the near infrared and red bands are required for the BRDF correction. The creation of such land masks is automated in the Leica XPro processing chain. The masks are embedded in the image statistics that are utilized by the image viewer and orthorectification process to apply the BRDF model.

The absence of explicit point correspondences among overlapping terrestrial laser scanning data limits the performance of automatic registration schemes. The popular Iterative Closest Point (ICP) and its variants, solve the correspondence problem implicitly while minimizing some distance metric. Other approaches perform low-level processing to obtain surface properties from which correspondences are established, and then they conduct the registration, which, in general is not as accurate as the ICP methods. This paper presents an approach that addresses the registration issue by dealing directly with the correspondence problem, without the use of derivative surface properties, except for local surface tangents

Many common digital elevation models (DEMs) use geographic coordinates, including NED, DTED, SRTM, GDEM, and NEXTMAP, with horizontal spacings in the range of 1/9" to 3". Many GIS operations, such as slope/aspect, reflectance or hillshade mapping, and viewsheds, require geometric knowledge of the relationship between horizontal and vertical spacing. Published discussions implicitly assume a rectangular UTM or UTM-like grid because they refer to a single value for data spacing, and some commercial software either requires reinterpolation to UTM before algorithms will work or allows only a single factor to relate degrees to meters, ignoring the significant changes that occur with latitude.

A method for shoreline extraction has been developed that is based on mean-shift segmentation and the integration of LiDAR data, satellite imagery and aerial orthophotos. This method first classifies LiDAR points as belonging either to a water surface or to land. The classification criterion is the homogenous nature of the Near-Infrared (N-IR) reflection of the water surface, the elevation, and color distribution. Subsequently a shoreline can be extracted by tracing the boundary between these two categories, water and land.

We present a method for the 3D reconstruction of objects from images captured in a surveillance setting using uncalibrated hand-held cameras. The images considered are of distant objects occupying a small portion of the field-ofview (FOV); have been captured in a non-systematic manner from varying aspects, distances, and angles; and have no a priori target information for 3D coordinates or scale. The current algorithms used to estimate camera orientations and perform 3D reconstruction rely to some degree on initial approximations of camera orientation and/or 3D coordinates of the target object or control points. Parameter initialization in most surveillance applications is problematic due to the non-regular camera arrangements and lack of target information. Using some of the strengths of the orthogonal model, this paper presents a robust initial approximation method suited to the demands of surveillance imagery.

To take images at the same instant, two cameras must be connected together using special equipment to give the order to the camera once a button has been pressed. To avoid complication and to save money, two video cameras can be used from different positions. Once the movies are transferred to the computer, two images (one frame from each movie) can be selected as right and left images. Miss-selection of any of the frames or both will affect the 3D measurements accuracy.

Landsat Thematic Mapper (TM) images from 1988, 1994, 2006, Enhanced Thematic Mapper Plus (ETM+) images from 2001 and 2003, and China-Brazil Earth Resources Satellite (CBERS) image from 2009 were used to obtain historical land use and land cover maps. These maps revealed that the watershed experienced conversion of approximately 16% non-urban area to urban area between 1988 and 2009. The Long-Term Hydrological Impact Assessment (L-THIA) model was used to calculate direct runoff generation. The model was calibrated and validated using observed daily stream flow data collected at the outlets of the watershed, and then repeatedly run with different urbanization scenarios to investigate the hydrological response to land use changes. The simulation results of L-THIA model for the various urbanization scenarios indicate that when the impervious surface area changed from 3.4% of 1988 scenario to 20.5% of 2009 scenario, the average annual direct runoff depth would increase from 355 mm to 496 mm. The results also indicate that the annual direct runoff depth is highly correlated with the percentage of impervious surface area. When impervious surface area is less than 9.0%, the annual direct runoff depth will increase linearly with impervious surface area (R2=0.97); however, when impervious surface area is greater than 9.0%, the annual direct runoff depth will also increase linearly with impervious surface area (R2 = 1.00) but at much lower rate.

Burned area products derived from satellite images are used as input to determine biomass burning emissions. Appropriate assessment of the accuracy of burned area products is required to assess reliable emissions. This document provides validation results for four burned area products: GlobCarbon, MCD45, L3JRC and AQS. The study area is at the northern South American savannas along the Orinoco River since there is a rapid conversion of Amazonian forest to cattle pasture. A validation method was applied from 2001 to 2007 based on the comparison of commission and omission errors from 20 confusion matrixes with their respective efficient solution. Efficient solutions were determined using the “Pareto Boundary”. This method allows estimating the potential for improving burned area algorithms as well as evaluating the effect of pixel size on accuracy. A landscape metric was used to analyze the weight of the fragments’ distribution on global accuracy.

To build HiRISE image network with the best possible precision and accuracy, technical issues involving sensor geometry and absolute positioning need to be resolved. High-frequency random patterns, or “jitter”, in the rotation angles cause disagreements between HiRISE CCDs. To generate seamless topographic products, it is important to achieve coherence in the exterior orientation parameters between multiple CCDs. Also, new images should be registered to the existing global geodetic control network to achieve absolute positioning in global scale.

This paper presents an approach to LiDAR point clouds segmentation for building roofs. Normal vectors determined from the original LiDAR point clouds are used as a homogeneous criterion representing planar roof planes. Segmentation is then performed iteratively by minimizing an energy function formulated as a multiphase level set framework. With multiphase level set formulation, up to n disjoint sub-regions can be segmented at a time by log2n level set functions.

A Novel Confidence Metric
Authors: Monica J. Cook and Dr. John R. Schott

The Landsat series is the longest body of continuously acquired, moderate resolution satellite imagery. The spatial and temporal resolution and coverage of Landsat make it an intriguing instrument for a land surface temperature product, which is an important earth system data record for a number of fields including climate, weather, and agriculture. Because current archived Landsat imagery has only a single thermal band, generation of a land surface temperature product requires an emissivity estimation and atmospheric compensation. This work, assuming imagery from a characterized and calibrated sensor and integration with ASTER derived emissivity data, focuses on the atmospheric compensation component by using reanalysis data and radiative transfer code to generate estimates of radiative transfer parameters. Along with an estimation of land surface temperature, the goal is to provide a confidence estimation for every pixel in a scene. Using water temperatures from buoy data, actual temperatures have been compared to predicted temperatures as validation of performance. These comparisons have shown acceptable performance when the atmosphere is well characterized, but larger errors when the atmosphere is not as well understood. The reanalysis data, radiative transfer code, bulk to skin temperature conversion, and lack of knowledge of atmospheric variation all complicate traditional error analysis. Various methods have been attempted, including error propagation based on perturbed atmospheres, regressions between metrics and error values, and thresholds based on atmospheric variables. Because of complications not faced by other large-scale products, a novel approach to error analysis will be developed by combining multiple approaches and data sources.

Rice Area and Probable
Authors: Ashraf Elshorbagy, Emad Imam and Mohamed Nour

Egypt faces a great challenge. Fixed water resources and increasing water demands. Rice is the main water–consuming crop planted in Egypt Delta. Thus mapping of where and when rice is planted is important. The planting occurs over a wide spatial and temporal span. Thus, rice mapping with traditional methods is doubtful. Elshorbagy (2013) developed a model for rice mapping utilizing MODIS (MOD09A1, MOD09Q1) products where the dynamics of Land Surface Water Index (LSWI), Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) throughout the rice-planting season were combined with an arable mapping module for rice area mapping. In the present study, ten years of historical multi-temporal MODIS imagery (2002-2011) were analyzed applying the developed model. For each main irrigation directorate an inventory of where and when rice was planted in the target period was mapped. The date intervals of maximum rice transplanting were identified. The most critical imagery dates for the model to well function were pinpointed. South-North rice transplanting lag trend was correctly mapped. The algorithm results were compared against the rice areas annual reports. There was good agreement between the estimated areas from the algorithm and the reports. Inter annual variation in rice areas was successfully mapped. In addition, the rice area and probable transplanting dates conforms to local planting practices. The findings of this study indicate that the algorithm can be used for rice areas and transplanting dates trends mapping on a timely and frequent manner.

With the decreasing price of electronics, more and more consumer grade or off-the-shelf digital cameras are flooding the market. This makes their use in close-range photogrammetric applications an inexpensive and convenient task. However, in order to be trusted for high quality object space reconstruction, these cameras must go through a calibration procedure. The purpose of this research project is to present a simple and practical way of performing camera calibration, so that the cost of the calibration will be proportional to the cost of the camera.

Sensitivity of environmental models to changes in variable parameters can be measured in a variety of ways. One simple, yet effect way to judge model sensitivity is to calculate a sensitivity index (Hamby, 1994). Standard sensitivity indices compare the standardized percent change in a parameter threshold of interest and the model's state variable from the default model to an altered model run, resulting in a normalized dimensionless index value (Lenhart et al., 2002; Millington et al., 2009).

This paper is concerned with stereo imaging for three-dimensional range estimation. The usual assumption for a two-camera system is that both cameras are stationary with respect to one another. In some imaging environments, however, physical vibrations are unavoidable. If these vibrations induce small movements of the cameras relative to each other, then the accuracy of any range estimates based on binocular disparity will suffer.

PIE Mapping technology
London Organising Committee of the Olympic and Paralympic Games (LOCOG) successfully managed the flow of traffic throughout this summer’s big event with the help of PIE Mapping. LOCOG, which is responsible for preparing and staging the London 2012 Games, enlisted the company’s help to form an effective strategy for managing the journey routing of around 20,000 ‘Games Family’ members which include; athletes, VIPs’, technical & team officials and over 21,000 media and broadcasters. Mark Bland, Head of Traffic Management and Parking at LOCOG says: “With a huge influx in visitors to the capital this summer, keeping London moving while ensuring that athletes, umpires, technical staff, broadcasters and other people associated with the games are able to get to their destinations expediently is a monumental task and an absolute priority for us. As a consequence, we have a mandate to provide those people with a system which would allow them to plan journeys throughout the duration of the games.” Using the official Olympic and Paralympic Route Networks (ORN/PRN) – a network of roads linking all key competition venues and sites – PIE came up with a solution to ensure the Games Family would be able to plan accurate and reliable routes across the host city throughout the Olympics. The solution The Games Family Journey Planner is a solution developed by PIE that is used throughout the duration of the games for all Games Family journeys that ensure correct route by specific days and accurate journey time calculation based on leave time or arrive time. Routes would change subject to time of day due to different Road Events effecting certain turn restrictions. The new journey planner provides users with an easy way to generate routes to and from Olympic destinations and postcodes such as stadiums and hotels while providing accurate arrival times. The service is fed by a regular stream of information provided to PIE by TfL meaning routes are provided based on current road and traffic conditions within the designated road networks. “All road data is processed into a special routing algorithm which means if there are delays on the roads, the Games Family Journey Planner may recommend an alternative route,” says Freddie Talberg, CEO, PIE. “While the technology which sits at the backend of this bespoke solution for LOCOG is complex, it’s incredibly simple to use. All the user needs to do is enter their login information and then provide a start and their destination locations within the Olympic or Paralympic network – the system does the rest, providing an appropriate route which can also saved as a pdf for quick reference.” PIE Mapping
Estimating Typical Four-Season
Authors: Xiaomin Du, Daiyong Cao, Guang Yang, Sergio Bernardes, Zhipeng Li, and Feng Li

Coal fire results in significant environmental impacts and coal losses in many countries, including the United States, India, and China. Multiple fire detection methods have been proposed. Many of these rely on thermal infrared (TIR) imagery. This study results from previous research on TIR, including our development of a self-adaptive gradient based thresholding method for coal fire delineation. We used field measurements and images acquired by the ASTER sensor onboard NASA’s Terra satellite and the TIRS onboard Landsat 8 to derive calibration parameters for a threshold estimation algorithm considering different solar radiation intensities, which impact radiance estimations from coal fire. We designed a simultaneous ASTER-field measurement plan in the Wuda coal field (China) and scheduled image collection for four periods, including the winter and the summer solstices (least and most intense solar radiation periods). Collection also included the vernal/autumnal equinoxes. Land surface temperature (LST) was collected before and after each satellite overpass in planned intense sampling block areas. LST field samples were integrated into 90-100 m TIR pixels. Data were combined with coal fire boundaries collected in the field and were used to validate the coal fires retrieved from four calibrated image by our temperature retrieving method, and the gradient-based threshold method. Results are a series of adjustment parameters for the fire detection method for four typical seasons. Correction parameters estimated by our method at the Wuda coal field can be extended to other fire areas lacking detailed studies, thus supporting surface temperature retrieval and underground coal fire delineation.

Orthoimage mosaics presume radiometric adaptation of the individual images, which is referred to as relative radiometric normalization (RRN). This paper presents an in-house developed RRN approach that aims for optimal adaptation of large blocks of Leica ADS line-scanner imagery for subsequent mosaicking. It assumes orthorectified and radiometrically preprocessed input image data – with camera calibration, atmospheric and BRDF corrections applied as described in a companion paper – but still allows for the adaptation of bigger radiometric differences. The RRN model incorporates the adaptation of brightness and contrast, both varying throughout each image according to location-dependent polynomials.

LIDAR is an active remote sensing technology which performs range measurements from the sensor and converts them into 3D coordinates of the Earth's surface. Recent advances in LIDAR hardware make it possible to digitize full waveforms of the returned energy. LIDAR waveform decomposition involves separating the return waveform into a mixture of Gaussians which is then used to characterize the original data. It plays an important role in LIDAR data processing because the resulting components are expected to represent reflection surfaces within waveform footprints and ultimately affect the interpretation of the data.
