Data from Federal Government Agencies
Several federal, state, and local agencies provide for GIS data and are usually the best place to look first for existing GIS data. The best source for these resources is found on the Spatial Analysis Guide, maintained by Carleton's GIS Specialist Wei-Hsin Fu. US Government Data.
See below for additional Federal data links:
-
The National MapUse the National Map to view selected data layers from the U.S. Geological Survey, U.S. Forest Service, U.S. Fish and Wildlife Service, the Bureau of Land Management, and more. The National Map is a collaborative project to provide current data and maps to the public. Data and maps can be viewed with merely a web browser, printed, or downloaded for use with GIS software. This is a great source for topographic maps (or data layers) and Digital Orthophoto Quadrangles.

EROS Data Center - USGSLand remote-sending data from USGS (Earth Resources Observation and Science (EROS) Center). Search and browse the collections of aerial and satellite imagery, elevation data, land cover, digital line graphs (DLG) and digital raster graphics (DRG). This massive archive includes 70 years of national data and 50 years of global data.
-
Geospatial Datasets - Data.govPart of the Geospatial One-Stop E-Gov initiative, this web site allows one to search or browse data categories of geospatial information. The GeoData Map Viewer allows you to view multiple Internet map services (like the National Map) using just your browser. Map servers viewable include the USGS, FEMA Hazard Maps, NASA Globe program, NOAA, and the BLM. State and regional servers are being added, including the Minnesota Metro GIS Data Finder.
