Published by Pacific Islands Ocean Observing System (PacIOOS) | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2015-09-22T00:00:00.000+00:00
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. For a grayscale hillshade image layer of this dataset, see "gu_pibhmc_all_bathy5m_hillshade" in the distribution links listed in the metadata.
