Data.Gov [ think Geo Data.gov!]… Improving access to Federal Geospatial data – A great, new geospatial resource is available from Data.gov – in a nutshell… 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. Users can browse data and tools (click view entire Catalog) or simply use the handy pull-down on the main page to search for data by agency (EPA, CDC, FEMA, USGS etc…) very nice!
