Shuttle Radar Topography Mission



The Shuttle Radar Topography Mission collected topographic data over nearly 80 percent of Earth's land surfaces, creating the first-ever near-global data set of land elevations.

Animation of SRTM radar beams On February 11, 2000, the Shuttle Radar Topography Mission (SRTM) payload onboard Space Shuttle Endeavour launched into space. With its radars sweeping most of the Earth's surfaces, SRTM acquired enough data during its ten days of operation to obtain the most complete near-global high-resolution database of the Earth's topography.

The Shuttle Radar Topography Mission is an international project spearheaded by the National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration (NASA).
