AI-generated Key Takeaways
-
GMTED2010 provides global elevation data at a 7.5 arc-second resolution (approximately 231.92 meters).
-
The dataset incorporates data from various sources, primarily SRTM, and fills gaps with other elevation datasets.
-
It includes seven bands representing elevation statistics: minimum, maximum, median, mean, standard deviation, sample, and breakline emphasis.
-
GMTED2010 is freely available for use and is hosted by the USGS.
-
This dataset is ideal for applications requiring global elevation data, such as terrain analysis, hydrological modeling, and visualization.

Description
The Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) dataset contains elevation data for the globe collected from various sources at 7.5 arc-seconds resolution. 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.
