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.
In addition to the elevation products, detailed spatially referenced
metadata containing attribute fields such as coordinates, projection
information, and raw source elevation statistics have been generated on a
tile-by-tile basis for all the input datasets that constitute the
global elevation model.
