NASA Shuttle Radar Topography Mission Water Body Data Shapefiles & Raster Files V003Entry ID: SRTMSWBD
Abstract: The NASA SRTM data sets result from a collaborative effort by the National Aeronautics and Space Administration (NASA) and the National Geospatial-Intelligence Agency (NGA - previously known as the National Imagery and Mapping Agency, or NIMA), as well as the participation of the German and Italian space agencies, to generate a near-global digital elevation model (DEM) of Earth using radar ... interferometry. SRTM was the primary (and virtually only) payload on the STS-99 mission of the Space Shuttle Endeavour, which launched February 11, 2000 and ﬂew for 11 days.
The SRTM swaths extended from ~30 degrees off-nadir to ~58 degrees off-nadir from an altitude of 233 km, creating swaths ~225 km wide, and consisted of all land between 56 degrees south and 60 degrees north latitude to account for 80% of Earth’s total landmass.
The Land Processes Distributed Active Archive Center (LP DAAC) is responsible for the archive and distribution of NASA MEaSUREs SRTM, which includes the SRTM Water Body Data (SWBD) one-arc-second (~30 m) product.
