Global Bathymetry and Topography at 15 Arc Sec: SRTM15+ V2.1
<p>The global bathymetry and topography grid at 15 Arc Sec is the latest iteration of the SRTM+ digital elevation model (DEM) where the \"plus\" indicates the addition of ocean bathymetry from shipboard soundings and satellite-derived predicted depths. This DEM is a global elevation...

<p>The global bathymetry and topography grid at 15 Arc Sec is the latest iteration of the SRTM+ digital elevation model (DEM) where the \"plus\" indicates the addition of ocean bathymetry from shipboard soundings and satellite-derived predicted depths. This DEM is a global elevation grid with a spatial sampling interval of 15 arc seconds (approximately 500 x 500 m pixel size at the equator). New data consists of >33.6 million multibeam and singlebeam measurements collated by several institutions, namely, the National Geospatial-Intelligence Agency, Japan Agency for Marine-Earth Science and Technology, Geoscience Australia, Center for Coastal and Ocean Mapping, and Scripps Institution of Oceanography.
