Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) The U.S.
Geological Survey (USGS) and the National Geospatial-Intelligence Agency (NGA) have collaborated on the development of a notably enhanced global elevation model named the Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) that replaces GTOPO30 as the elevation dataset of choice for global and continental scale applications. Since the time GTOPO30 was completed, the availability of higher-quality elevation data over large geographic areas has improved markedly.
New data sources include global Digital Terrain Elevation Data (DTED®) from the Shuttle Radar Topography Mission (SRTM), Canadian elevation data, Spot 5 Reference3D data, and data from the Ice, Cloud, and land Elevation Satellite (ICESat). GMTED2010 provides a new level of detail in global topographic data. Digital Elevation Data - with SRTM voids filled using accurate topographic mapping. EarthExplorer.
