About the USGS Seamless Server


The National Map Seamless Server is the ultimate location to explore and retrieve data. U.S. Geological Survey (USGS) and the EROS Data Center (EDC) are committed to providing access to geospatial data through The National Map. An approach is to provide free downloads of national base layers, as well as other geospatial data layers. These layers are divided into framework categories.

  • Places
  • Structures
  • Transportation
  • Boundaries
  • Hydrography
  • Orthoimagery
  • Land Cover
  • Elevation

Along with providing access to the data, the site contains:

  • Tutorial to help with downloads
  • Information about the downloadable products
  • Frequently Asked Questions
  • Links to product homepages and information pages

The National Map Seamless Server is always growing with new data, tools, features, and much more.
