NOAA/PIBHMC 5-m Bathymetry: USMOI: Johnston Atoll
A 5-m resolution gridded digital elevation model (DEM) for the bathymetry (ocean depth) surrounding Johnston Atoll in the Central Pacific Ocean, a U.S. Minor Outlying Island (USMOI), compiled from ship-borne multibeam sonar surveys merged with coastal bathymetry derived from multipectral IKONOS satellite data. Almost complete bottom coverage was achieved in depths between 0 and 150 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_bathy5m_hillshade" in the distribution links listed in the metadata.
