Sources for Digital Elevation Models (DEMs)

  • Global
    • ETOPO1 is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. It was built from numerous global and regional data sets, and is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions. Historic ETOPO2v2 and ETOPO5 global relief grids are deprecated but still available.
    • The CGIAR-CSI GeoPortal is able to provide SRTM 90m Digital Elevation Data for the entire world.
  • USA
    • USGS National Map server distributes seamless 1/9-second (~10 m) and 1/3-second (~30m) data, simultaneously with other useful data
    • "Seamless 10- and 30-meter digital raster elevation data covers the conterminous U.S., Alaska, Hawaii, Puerto Rico, and Virgin Islands. Features periodic updates to incorporate the best available source data (primarily USGS 10 and 30-meter DEMs) Seamless SRTM "Finished" 1 arc second (30 meter posting) digital raster elevation covers the United States and its territories and possesions. Seamless SRTM "Finished" 3 arc second (90 meter posting) digital raster elevation covers the globe between 60 degrees N and 56 degrees S latitude. SRTM "Finished" was supplied by NGA." Seamless 1/3 arc second data is now available for the entire continental United State. Seamless 1/9 arc second data is available for a few select locations. Search for covered areas by using "layer extent." To change change download options to different resolutions use "modify data request."
    • "This Coastal Relief Gridded database provides the first comprehensive view of the US Coastal Zone; one that extends from the coastal state boundaries to as far offshore as the NOS hydrographic data will support a continuous view of the seafloor. In many cases, this seaward limit reaches out to, and in places even beyond the continental slope. The National Geophysical Data Center is addressing the need for topographic-bathymetric relief models that integrate land and seafloor elevations by assembling a gridded database which merges the US Geological Survey 3-arc-second DEMs with a vast compilation of hydrographic soundings collected by the National Ocean Service and various academic institutions. Eight CD-ROMs are available covering the US East, Gulf, and West Coasts (see above). In addition to the US Geological Survey and National Ocean Service data, volumes 3 through 5 also include bathymetric contours from the International Bathymetric Chart of the Caribbean Sea and the Gulf of Mexico project. These eight volumes, plus volumes 9 and 10 (Puerto Rico and Hawaii) are also available on one DVD-ROM. All volumes are also available for free download."
    • DEMs of coastal regions - this source will be phased out but the data will still be available - see next.
    • Coastal data for the US: DEMs(LIDAR,IfSAR), Land Cover, Imagery, Benthic Habitat, NOAA Composite Shorelines, U.S. Marine Boundaries, Georegulations.
