On November 20, 2014, the LP DAAC released additional tiles in the NASA SRTM Version 3.0 Global 1 arc second dataset (SRTMGL1), to include coverage over Europe, North America, and South America. This coincides with the newly processed areas released by the USGS on November 17th, 2014, available through EarthExplorer.
The NASA Version 3.0 SRTM Global 1 arc second product is void-filled using elevation data from ASTER GDEM2, USGS GMTED 2010, and USGS National Elevation Dataset (NED). For detailed information regarding SRTM please see the SRTM User Guide.
SRTMGL1 coverage now includes Africa, Europe, North America, and South America in 1° X 1° tiles at 1 arc second (about 30 meters) resolution.
This is the second release in the series providing access to additional NASA SRTM Version 3.0 Global 1 arc second (SRTMGL1) data coinciding with areas released by the USGS. The rest of the globe will be released in the future. We will be adding news announcements as the new areas are added to our data clients.
