Data.gov is Live
Data.gov is the U.S. portal for data or in its own words: “The purpose of Data.gov is to increase public access to high value, machine readable datasets generated by the Executive Branch of the Federal Government.” The FAQ is here and this question is interesting:
What are some resources for viewing geospatial datasets?
The geospatial datasets available on Data.gov are provided in up to three open file formats: Keyhole Markup Language (KML), Compressed Keyhole Markup Language (KMZ) and ESRI Shapefile. These datasets are all viewable in many commercial and freely available applications. More information about Geographic Information System (GIS) software can be found by doing a web search.
