USDA:NRCS:Geospatial Data Gateway

The USDA:NRCS:Geospatial Data Gateway - The Geospatial Data Gateway or Geo-Data Gateway provides easy and consistent access to natural resource data for United States, including high-resolution recent color NAIP imagery. You can search for available data by geographic area such as county or state, use our point and click map tool to find your area of interest; using a gazetteer, or by entering latitude and longitude coordinates. You can also search for data by theme, such as digital ortho imagery, digital elevation models (DEMs), or soils. You can then view a thumbnail, or sample of the data you've chosen to know if you want a copy of the data. If you do, you can either download the data directly onto your machine, pick it up via our ftp site, or order it on media such as CD. Of course, all of this data is ABSOLUTELY FREE for download.
