Global Bathymetry and Topography at 15 Arc Sec: SRTM15+V2.0
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 …
