Maponics continues to pioneer GIS data products and is the first to provide School Attendance Zones Boundaries as part of a comprehensive dataset that includes not only school attendance zones but nationwide school district boundaries and public and private school locations and profiles.
A huge undertaking for Maponics is their newly released School Attendance Zones Boundaries. Darrin Clement filled me in on the product which is included in their Maponics School Boundaries product.
“Most people are familiar with the concept of a school district, those areas governed by some local government, usually a school board,” said Clement. “Within a school district there might be multiple elementary schools and so the challenge for people trying to buy a home, they may know that the area in which they are considering buying a home is in a good school district overall. Out of five elementary schools there are only two of them that are good so I make sure I buy a home so my kids can go to that school and those are governed by what are called school attendance zones. That’s what we have now mapped out. Customers in the real estate space are pleased as it will attract new consumers to their websites and is an additional tool in determining what homes to buy.”
In most cases, if a school district has five elementary schools, the households that go to each school are based on location, said Clement. In most cases the school district has done some level of mapping themselves, so usually Maponics establishes a strong relationship with that school district so they give them that information and then they digitize it.
“From a school district standpoint we have the entire U.S.; from a school attendance zone standpoint, we’ve got about 20 percent of the student population mapped out. We have the information – how many students attend certain schools,” said Clement.
An example is in Miami, where there might be 10 school districts in the county, but within those districts there might be hundreds of school attendance zones. You’ve got different attendance zones for elementary school than middle school than high school and they don’t always overlap properly. “By the time we’re done, there will be about 120,000 school attendance zones, whereas I think there are only 15,000 or so school districts,” said Clement. “And there are cases where it’s a single zone district, in small communities, therefore the district is the attendance zone.”
For Attendance Zones Maponics has put the school location on the rooftop of the school. “By this time next year we’ll have 100 percent of the country covered at the School Attendance Zone level as well,” said Clement.

“Thirteen-year-old Jordan Romero partnered with ESRI to share his Mount Everest climb with the world via geographic information system (GIS) technology. The Jordan Romero Web site features an ESRI GIS mapping application that integrates Web services to track Romero’s journey. The application lets the public see Team Romero’s location in near real time, explore daily tracks, view distance and elevation statistics, and browse weather and route information. The application also gives geographic context to social media—for example, Flickr photos and Twitter posts from the team throughout the trip,” according to a press release issued today.
The thirteen-year-old Romero is already a mountain climbing pro, having already climbed six of the “Seven Summits,” the tallest mountain on each of the seven continents. Joined by his father, Paul Romero, and his stepmother, Karen Lundgren, the trio left for Everest on April 5 and expects to reach the summit some time this month. The trio have reached all six summits together. The young Romero is aiming to be the youngest person ever to summit Everest, which would beat the current record by three years.

In a conversation with vice president of product marketing Mladen Stojic, here’s what’s new in the ERDAS 2010 10.1 release:
1) new capability called LPS eATE – an enhanced automated terrain extraction tool that automatically extracts very accurate and very dense point clouds from imagery;
2) ERDAS APOLLO software application, ERDAS’ enterprise solution for managing and delivering large quantities of geospatial information, was released a couple of years ago. It works on a server and manages data whether its high volumes of image data, terrain data or vector for customers that have a lot of diverse data. What is new with this release is the Microsoft SQL support (noted below) and ERDAS APOLLO Feature Interoperability. ERDAS APOLLO Feature Interoperability is a new module that provides a DGN Connector to ERDAS APOLLO, enabling direct access to MicroStation’s DGN v7 and v8 format files via web services.
3) ERDAS has an ongoing partnership with Microsoft, which is now also reflected within the APOLLO application. Microsoft has been spending more and more money on its spatial capabilities on its SQL Server platform, so ERDAS is now working and will support the Microsoft SQL Server database in ERDAS APOLLO applications
4) Defense market, homeland security and intelligence are interested in the new “add-on” to ERDAS’ existing Stereo Analyst product. StereoAnalyst for ArcGIS Extension that ERDAS has built to serve Stereo Analyst customers who need additional Defense formats in the ArcGIS environment. This product collects native 3D data directly at a much greater accuracy rate with direct sensor model support for those classified sources on the ArcGIS platform.
5) According to Stojic,
Pixel-wise data extracted with LPS eATE. Point cloud, 3D, and cross sectional views of the surface are shown in Fugro Viewer.
ERDAS has been building high performance server systems and with this 10.1 release they have done even more to produce what they say is the fastest server in the market for serving geographic data and information.

A University of New South Wales professor said surveyors and GIS professionals are sorely needed in the rural areas. Fewer locals are taking courses or returning from college to their country roots to work in those areas.

“Many incidents (such as the events of 9/11 and the Worcester Cold Storage Warehouse fire that killed six firefighters) have highlighted the need for an accountability system to accurately locate, track, monitor, and visualize the locations of responders on a geospatial map. This will allow incident commanders and tactical-decision makers to virtually observe personnel movements in real time to avoid loss of life.”
This article talks about the “development of the geospatial location accountability and navigation system for emergency responders (GLANSER). The system is a ‘cocktail solution’ in which several components have been fused together to provide an estimate of the user’s location, whether inside or outside a building. We have combined GPS, IMU, ultrawide-band ranging radio, Doppler radar, as well as a magnetometer, compass, pedometer, and altimeter, to fit into a 2×4×6in3 wearable electronic unit. This combination of sensors works in harmony so that when GPS is not available, or in periods of suboptimal RF ranging, other signals are exploited”

At AU it appeared that geospatial had an uncertain future at Autodesk. Senior director, Infrastructure Modeling Product Line Paul McRoberts stated at Autodesk’s AEC Technology Day this week that geospatial is the underlying component for all of Autodesk products. The FDO platform is extensible open source software that can be noted in transportation, water and waste water, land development, power and energy.
McRoberts said that 24% of the gross revenue collected by AEC firms is for planning, according to an American Council of Engineering Companies (ACEC) study. It might appear that the role of geospatial at Autodesk is visual in nature: modeling and visualization for water, transportation, energy and water and wastewater, where getting public approval is primary to getting projects off the ground. What is needed here is a way to show a workflow including location and geospatial data. The technologies spoken most about – 3ds Max for visualization and Dynamite VSP Exporter are for showing how problems can be solved, interoperability, and being able to migrate information to others.
The laser scanning environment and lidar data play a part in this. McRoberts said that surveying may become a thing of the past. With the need in many places for ground truth data, particularly in areas that aren’t readily accessible with laser scanning equipment or lidar, I think it may be a long time before this is realized.
“Digital cities,” a hot buzz term of a year or two ago, will now go by the name “sustainable cities” as one part of a greater vision including extension of assets such as tranmission lines into rural communities. It is part of the scope of LandXplorer, in its quest to address large scale projects and visualization. McRoberts said LandXplorer holds a GIS layer underneath that contains real data.

Touch Inspect is a handheld inspection app that runs on Windows Mobile 6, 6.1 and 6.5, with the Mobile PC and tablet edition running on Windows XP, Vista and Windows 7.
This app was designed to capture a wide variety of data types in the field and employs GPS to allow workers to map the location of individual assets as well as search for them by proximity to the user. The company Mobile Epiphany got its start in the video game industry, so it naturally makes use of multimedia features, so users can have detailed visual information on assets. “For example, a utility inspector could take a picture of a metal power pole then use the drawing tool to circle rust spots in the picture and save it to the inspection history. Inspectors who see the pole at some later date could then call up the picture for comparison, to see if the rust spots have grown, and decide whether or not to recommend maintenance. Mobile epiphany refers to this as one part of field decision support.”
Mobile Epiphany’s CEO, Glenn Kletzky said that the application is already built so users can start using it almost immediately.
Data is stored on the handheld device itself, and transmitted to the database when a connection is available. Data is not lost if a connection is lost, rather, it is stored on the device until a transmission is available. Data can also be transmitted in real time and reports can be auto-generated in moments.

Counting the nation’s residents only comes around once every ten years, and each time it does, new technologies have been created in that period of time that make it easier to get a figure on the population.
What is important about the Census Bureau is that it collects valuable information about city and county trends. This can range from data about the age of residents in a particular county or city, the median household income, jobless figures, and housing data. What effect has the recession had on income and joblessness? What languages other than English do residents speak?
Another less publicized fact about the U.S. Census is that it is not always easy to collect this information. Most households receive their Census forms in the mail. The new forms have a streamlined questionnaire this time around. However, there are some people living in the back country who don’t receive their mail at their homes.
In northern mountain communities in New Mexico, for example, there is significant snowfall and the U.S. Mail just simply doesn’t deliver there in the winter. What has happened this year is that census takers have strapped on snowshoes and cross-country skis to slog their way to some out of the way cabins.
One census taker reported driveways that are three miles long with very deep snow.
