We have recorded 18 video interviews at the Esri User Conference in San Diego this week. The conference was extremely well attended with more than 15,000 attendees, more than 200 exhibitors, and 100’s of great presentations. The weather was perfect in San Diego making the conference even more enjoyable.
The following video interviews will be published in the coming weeks as we complete the editing process:

ScribeKey, LLC, (www.scribekey.com) a Boston area GIS data integration company specializing in metadata and data cleansing, has released version 1 of the GIS Data Profiler. The profiler, an ESRI ™ArcGIS 9 or 10 add-on, captures information describing the structure, contents, and meaning of geospatial datasets. This information, which includes highly detailed, concise descriptions of feature classes, tables, data fields, value lists, indexes, metadata, geodatabase relationships, subtypes, domains, and more, is saved by default in an easy-to-use and share MS Access database. Profile information can also be saved to larger backend databases such as SQL Server or Oracle. The profiler can process Shapefile, Personal Geodatabase, File Geodatabase, SDE, and SDC datasets.
Data profilers, typically found in enterprise business intelligence and decision support environments, are used to help with a wide variety of data-centric projects including dataset revision tracking, data QA/QC, application development, migration and conversion ETL, schema matching, metadata and data dictionary development, and more. Essentially, data profiling provides the ability to generate a highly structured and detailed table of contents and index for a database. Profiling makes it much easier to search through, become familiar with, and make the best use of even the largest data stores.

ShareMap is slowly phasing out from beta stage. Feature set is almost complete and dozens of maps created with ShareMap enriches multiple Wikipedia articles.
There are two major features introduced recently:
OpenStreetMaps is enormous source for geospatial data. Implantation of import mechanism from OSM was one of first features of ShareMap. But sometimes OSM data is not enough, especially when we try to create historical map. For example if we want to create map of dismantled tramway system in Cleveland we cannot find information about track position at OSM. But we can reuse pre war map of system (with expired copyrights, so it is 100% comply with Creative Commons license). We can treat this old map as overlay to our interactive map, but first of all we have to calibrate it. In simple words calibration is just selecting of several calibration points on raster map (old one) and interactive map. After point selection system warps. Under the hood well known open source GDAL library is used. In this video map calibration process is described in detail:

This image, captured by the Pléiades 1A satellite, shows the area of Colorado affected by forest fires, enhanced with additional information by Astrium Services’ geo-experts. The images from the Earth observation satellites operated by Astrium Services (Pléiades, SPOT, etc) are often used to support homeland security and emergency services personnel following a disaster.
Launched in December 2011, Pléiades 1A generates 50cm resolution imagery, following resampling, which is used for precision mapping and photo analysis.

Having identified enormous developmental potential in the trending topic of connected vehicles, Taiwan’s Industrial Technology Research Institute (ITRI) is looking for forward-thinking prototypes in the 2012 European Satellite Navigation Competition (ESNC). Eight finalists will be invited to the institute’s research campus in Taiwan to present their pilot projects. The winner and finalists will receive cash prizes ranging from EUR 1,000 to EUR 10,000.
Intelligent cars made possible by modern navigation and communication technologies are a popular topic with automotive manufacturers and customers alike. Automated parking functions and systems that warn drivers of braking vehicles and sharp curves are just the beginning. Following its major success in 2011, ITRI is offering a prototyping prize in the field of connected vehicles for the second time in this year’s ESNC. The institute’s stated objective – “Connect Autos Tightly to ICT from V2X” – reflects its search for innovative solutions that combine modern satellite navigation and smart vehicle communication technologies.

Morten Nielsen previews the efforts being made with ArcGIS Runtime SDK within Windows 8 Metro style applications.
Windows 8 essentially runs in two different modes — one is like the traditional windows environment in Windows 7.
The second mode is the Metro style. The Metro style apps are designed to be full screen, beautiful, connected to the people and content you care about, interactive and touch-first, and work in a variety of layouts and form factors. Metro style apps takes center stage, while the operating system remains in the background.

The WorldMap platform is being developed by the Center for Geographic Analysis (CGA) at Harvard to lower barriers for scholars who wish to explore, visualize, edit, collaborate with, and publish geospatial information. WorldMap is Open Source software.
The system attempts to fill a growing niche between powerful desktop-bound mapping applications, and lightweight web map solutions with limited capacity.
If you find WorldMap data or technology useful in your research we would love to hear from you. Understanding how the system is being used and where it needs improvement is critical as we evolve the system together.
WorldMap provides researchers with the ability to:
