Description

The Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) dataset contains elevation data for the globe collected from various sources. The version of the dataset available here is Breakline Emphasis, 7.5 arc-seconds resolution. Breakline emphasis maintains the critical topographic features (streams or ridges) within the landscape by maintaining any minimum elevation or maximum elevation value on a breakline that passes within the specified analysis window. More details are available in the dataset report.

The primary source dataset for GMTED2010 is NGA's SRTM Digital Terrain Elevation Data (DTED®, http://www2.jpl.nasa.gov/srtm/) (void-filled) 1-arc-second data. For the geographic areas outside the SRTM coverage area and to fill in remaining holes in the SRTM data, the following sources were used: non-SRTM DTED®, Canadian Digital Elevation Data (CDED) at two resolutions, Satellite Pour l'Observation de la Terre (SPOT 5) Reference3D, National Elevation Dataset (NED) for the continental United States and Alaska, GEODATA 9 second digital elevation model (DEM) for Australia, an Antarctica satellite radar and laser altimeter DEM, and a Greenland satellite radar altimeter DEM.

This dataset replaces the GTOPO30 Elevation Model.
