    • SRTM30+ Global 1-km Digital Elevation Model (DEM): Version 11: Bathymetry

    Metadata Updated: October 7, 2023

    Global 1-km resolution bathymetry from the 30 arc-second SRTM30+ gridded digital elevation model (DEM). Based on the Smith and Sandwell global 1 arc-minute grid between latitudes +/- 81 degrees. Higher resolution grids have been added from the LDEO Ridge Multibeam Synthesis Project, the JAMSTEC Data Site for Research Cruises, and the NOAA/NCEI Coastal Relief Model. Arctic bathymetry is from the International Bathymetric Chart of the Oceans (IBCAO). For a grayscale hillshade image layer of this dataset, see "world_srtm30plus_bathy1km_hillshade" in the distribution links listed in the metadata.
