Topography and Bathymetry Model
Description: 1-arc minute model of Earth’s global relief, including surface topography and seafloor bathymetry
Authors: NOAA National Centers for Environmental Information (NCEI)
Description: The General Bathymetric Chart of the Oceans (GEBCO) consists of an international group of experts who work on the development of a range of bathymetric data sets and data products, including gridded bathymetric data sets, the GEBCO Digital Atlas, the GEBCO world map and the GEBCO Gazetteer of Undersea Feature Names.
Authors: A complete A to Z listing of GEBCO contacts
Description: GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer)
Authors: EROS, NASA, UNEP/GRID, USAID, INEGI, GSI, MWLR, SCAR
[toggle title=”SRTM15_PLUS and SRTM30_PLUS”]
Description: SRTM30_PLUS is a global topography data set that the grid resolution is 30 seconds which is roughly one kilometer. SRTM15_PLUS is an updated model based on V11 of the SRTM30_PLUS, and its grid resolution is 15 seconds.
Authors: David T. Sandwell, Joseph J. Becker, Chris Olson, Amber Jackson, Rachael Munda
Description: The SRTM digital elevation data, produced by NASA originally, is a major breakthrough in digital mapping of the world, and provides a major advance in the accessibility of high quality elevation data for large portions of the tropics and other areas of the developing world.
[toggle title=”ASTER GDEM”]
Description: The ASTER Global Digital Elevation Model (ASTER GDEM) is generated from data collected from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), a spaceborne earth observing optical instrument. It covers the entire land surface of the Earth at high resolution.
