Data details

Name Shuttle Radar Topography Mission Water Body Dataset (SWBD)
Note Body Data files are a by-product of the data editing performed by the National Geospatial - Intelligence Agency (NGA) to produce the finished SRTM Digital Terrain Elevation Data Level 2 (DTED 2). In accordance with the DTED 2 specification, the terrain elevation data have been edited to portray water bodies that meet minimum capture criteria. Ocean, lake and river shorelines were identified and delineated. Lake elevations were set to a constant value. Ocean elevations were set to zero. Rivers were stepped down monotonically to maintain proper flow. After this processing was done, the shorelines from the one arc second (approx. 30-meter) DTED 2 were saved as vectors in ESRI 3-D Shapefile format.

Hydrographic network Partially Available in Rapid Mapping SDI. Accuracy is lower than threshold. Coverage is not complete: SRTM has collected data over most of the land surfaces that lay between 60 degrees north latitude and 54 degrees south latitude. That's about 80% of all the land on the Earth. Nov. 17, 2017, 10:19 a.m. June 23, 2022, 12:13 p.m.
