New SRTM15+ Global Bathymetry and Topography Dataset Released
OpenTopography is pleased to announce the release of the SRTM15+ V2.1 global bathymetry and topography dataset. This dataset 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).
