Evidence-backed facts

  1. The National Map access API supports discovery and download of USGS elevation, imagery, hydrography, boundaries, structures, maps, and other geospatial products. informative
  2. Public product discovery does not require an account and does not grant dataset publication, survey, land-title, emergency, or map-revision authority. informative
  3. Clients must bind dataset, extent or geometry, date, product, format, paging, and maximum-result constraints and use returned download links and metadata rather than guessing file locations. informative
  4. Products have independent source dates, scales, resolutions, processing methods, and accuracy limits and do not prove property boundaries, current field conditions, navigation safety, or legal jurisdiction. informative
