Shuttle Radar Topography Mission (SRTM)
The Shuttle Radar Topography Mission (SRTM) is a digital raster elevation geospatial dataset divided in to one degree blocks for the surface of the earth. This set covers over 80 per cent of the Earth's land surface, everything between 60 degrees North and 56 degrees South latitude. A coverage map can be viewed at the SRTM Website. SRTM data has been provided to the Map and Data Centre by Land Information Worldwide Mapping, LLC.
