A 5-m resolution gridded digital elevation model (DEM) for the bathymetry (ocean depth) surrounding Guam compiled from ship-borne multibeam sonar surveys merged with bathymetry derived from aerial LiDAR data. Almost complete bottom coverage was achieved in depths between 0 and 400 m. Data collected by the Pacific Islands Benthic Habitat Mapping Center (PIBHMC) in support of NOAA's Coral Reef Conservation Program. Not to be used for navigational purposes.
