summary: A 20-m resolution gridded digital elevation model (DEM) compiled from ship-borne multibeam sonar surveys for the bathymetry (ocean depth) surrounding Johnston Atoll in the Central Pacific Ocean, a U.S. Minor Outlying Island (USMOI). Almost complete bottom coverage was achieved in depths between 8 and 4100 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 "jat_pibhmc_all_bathy20m_hillshade" in the distribution links listed in the metadata.
