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.
