SRTM30+ Global 1-km Digital Elevation Model (DEM): Version 11: Land Surface


A global 1-km resolution land surface digital elevation model (DEM) derived from United States Geological Survey (USGS) 30 arc-second SRTM30 gridded DEM data created from the NASA Shuttle Radar Topography Mission (SRTM). GTOPO30 data are used for high latitudes where SRTM data are not available.
