Flow Accumulation, LV Watershed, raster, 2000 Reference Information and Units: GCS: WGS 1984 Projection: EPSG:102024 (Lambert Conformal Conic Africa), Resolution: ~30 meters File Naming Convention: v2_flow_accum Data Origin: SRTM GL1: NASA Shuttle Radar Topography Mission Global 1 arc second V003 Sensor: SRTM Data Description: NASA Shuttle Radar Topography Mission (SRTM) datasets 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. The purpose of SRTM was to generate a near-global digital elevation model (DEM) of the Earth using radar interferometry. SRTM was a primary component of the payload on the Space Shuttle Endeavour during its STS-99 mission. Endeavour launched February 11, 2000 and flew for 11 days. SRTM collected data in swaths, which extend from ~30 degrees off-nadir to ~58 degrees off-nadir from an altitude of 233 kilometers (km). These swaths are ~225 km wide, and consisted of all land between 60° North (N) and 56° South (S) latitude. This accounts for about 80% of Earth’s total landmass.
