    • NOAA/PIBHMC 5-m Bathymetry: CNMI: Alamagan

    Metadata Updated: October 7, 2023

    A 5-m resolution gridded digital elevation model (DEM) for the bathymetry (ocean depth) surrounding Alamagan Island in the Commonwealth of the Northern Mariana Islands (CNMI) 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 380 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 "mp_pibhmc_ala_bathy5m_hillshade" in the distribution links listed in the metadata. For further details about this dataset, please see: https://www.soest.hawaii.edu/pibhmc/cms/data-by-location/cnmi-guam/alamagan-island/.
