Global DEM Data


Release Date: Thursday, January 8, 2015

This is 7.5 arc-second GMTED2010 data reformatted and edited to meet the needs of ERDAS IMAGINE applications. It is made available to ERDAS IMAGINE users free of charge. A coarser resolution version (30 arc-second) is distributed with ERDAS IMAGINE as a default terrain, in the Elevation Library Manager, to use for purposes such as orthorectification.

GMTED2010 is a multi-resolution global terrain dataset with spatial resolutions of either 30, 15 or 7.5 arc-seconds (i.e. approximately 1 kilometer, 500 meters and 250 meters, respectively). To use the 7.5 arc-second data, download, unzip and replace the 30 arc-second data delivered with ERDAS IMAGINE 2015. The 30 arc-second GMTED2010 data can be found at: <HOME>\etc\globalterrainsources.

Note: The 7.5 arc-second data does not cover Greenland and Antarctica.

GMTED2010 data is courtesy of the U.S. Geological Survey (USGS). The USGS home page is Further information regarding GMTED2010 can be found at
