attribute NC_GLOBAL summary String A 90-m (3 arc-second) resolution gridded digital elevation model (DEM) for the bathymetry (ocean depth) surrounding American Samoa, including the islands of Tutuila, Ofu, Olosega, and Tau. It is referenced to a vertical tidal datum of Mean High Water (MHW) and was compiled from various data sources including: NOAA National Centers for Environmental Information (NCEI), formerly the National Geophysical Data Center (NGDC); the U.S. Geological Survey (USGS); Naval Oceanographic Office (NAVOCEANO); Gaia Geo Analytical; and other federal, state, and local government agencies, academic institutions, and private companies. Developed for the National Tsunami Hazard Mitigation Program (NTHMP) to support NOAA's tsunami forecasting and modeling efforts. Not to be used for navigational purposes.
