City GIS Sites
By Will Craig, University of Minnesota
A recent article by the Wall Street Journal highlights new efforts by cities to share geographic data with citizens and businesses. Many of these new mapping efforts are based on Google Earth or ESRI’s ArcGIS Explorer.
Portland Oregon, for example, provides maps of recent crimes, building permits, city capital improvement projects, airport noise, and more. With the use of Google Earth, many maps can be displayed in 3-D. For more information see http://www.PortlandMaps.com
Denver provides many of the same types of maps at http://DenverGov.org/maps, though their maps tend to be less current.
The thrust of the article is that cities are getting data out of internal files and putting them out where people can use them. This is good business for these cities, because it saves staff time while encouraging an informed citizenry.
“New software adds a whole new dimension to local-government data,” by Kevin J. Delaney, was published March 26 in the Wall Street Journal. A preview of the article is available to online at http://online.wsj.com/article/SB117434536114541987.html
