GEE Dataset - GMTED2010: Global multi-resolution terrain elevation data in 2010

The Global Multiresolution Terrain Elevation Data 2010 (GMTED2010) dataset contains global elevation data collected from a variety of sources. The version of the dataset available here is Breakline Emphasis, 7.5 arcsecond resolution. Breaklines emphasize the preservation of key topographic features (streams or ridges) within the landscape by maintaining any minimum or maximum elevation values ​​across breaklines within a specified analysis window. More details are provided in the dataset report.

The primary source data set for GMTED2010 is NGA's SRTM Digital Terrain Elevation Data (DTED®, https://www2.jpl.nasa.gov/srtm/ ) (fill in the blank) 1 arc second data. For geographic areas outside the SRTM coverage area and to fill remaining holes in the SRTM data, the following sources were used: non-SRTM DTED®, Canadian Digital Elevation Data (CDED) at both 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, satellite radar and laser altimeter DEM for Antarctica, and satellite radar altimeter DEM for Greenland .

This dataset replaces the GTOPO30 elevation model.

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®, https://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.
