Srtm digital elevation model download
The first release of Shuttle Radar Topography Mission (SRTM) data was provided in 1-degree digital elevation model (DEM) tiles from the USGS ftp server (ftp://) in The data was released continent by continent, as and when the data was processed by NASA and the USGS. Introduction - Methodology - Acknowledgements - Version History. 23 Sep Void-Filled "SRTM Plus" Released (SRTM NASA V3) NASA has released a void-filled version of the Shuttle Radar Topography Mission digital elevation model, known as "SRTM Plus" or SRTM NASA Version 3. Most voids are filled with elevation data from the ASTER GDEM2 (Global Digital Elevation Model Version 2). SRTM data - Data Products - News - SRTM Mission. 24 Aug The NASA Version SRTM Global 1 arc second product is void-filled using elevation data from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model 2 (GDEM2), USGS Global Multi-resolution Terrain Elevation Data (GMTED) , and USGS National Elevation Dataset (NED).
SRTM Non-Void Filled elevation data were processed from raw C-band radar signals spaced at intervals of 1 arc-second (approximately 30 meters) at NASA's Jet Propulsion Laboratory (JPL). This version was then edited or finished by the Vertical Datum, EGM96 (Earth Gravitational Model ). Vertical Units, Meters . 22 Feb Description. This Shuttle Radar Topography Mission (SRTM) DEM was created from level 1 data which was cleaned and had holes patched. The data does not incluse the Shetland Islands as SRTM data becomes unreliable at 60N. The cell size is close to 90m. It covers the whole of the UK. The data is. 27 May - 5 min - Uploaded by PCI Geomatics Learn how easy it is to search and download freely available Shuttle Radar Topographic.
21 Feb SRTM DEM. NASA only needed 11 days to capture Shuttle Radar Topography Mission (SRTM) meter digital elevation model. Back in February , the Space Shuttle Endeavour launched with the SRTM payload. Using two radar antennas and a single pass, it collected sufficient data to generate a.
