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. GMTED2010 provides a new level of
detail in global topographic data. The GMTED2010 product suite contains
seven new raster elevation products for each of the 30-, 15-, and
7.5-arc-second spatial resolutions and incorporates the current best
available global elevation data. The new elevation products have been
produced using the following aggregation methods: minimum elevation,
maximum elevation, mean elevation, median elevation, standard deviation
of elevation, systematic subsample, and breakline emphasis.
