SRTMGL30_002

NASA Shuttle Radar Topography Mission Global 30 arc second V002

Version 002
  • 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 global thirty-arc-second (~1000 m) product. ------------------------------------ Data Set Characteristics: Geographic Extent: Global between 90° North and 60° South latitude Scene Coverage: 50° x 40° tiles Image Dimensions: 6000 x 4800 Total Number Tiles: 27 Tile Volume: 1 GB Compression Type: zip File Format: Zip, DEM Map Projection: Geographic latitude and longitude Datum: WGS84/EGM96 Pixel Size: 30 arc second (~1000 m)
