SRTM Version 3.0 Global (90m) and United States (30m) Elevation Data Now Available
The Shuttle Radar Topography Mission (SRTM) obtained 90 meter (3 arc-second) resolution data on a near-global scale (between 56 degrees South and 60 degrees North latitude) and 30 meter (1 arc-second) resolution over United States, providing a valuable global topographic dataset. The SRTM data were collected during an 11-day mission in February of 2000 from a radar system onboard the Space Shuttle Endeavor. The SRTM project was led by the National Geospatial-Intelligence Agency (NGA) and NASA.
