  Description:
    Abstract: California-vicinity bathymetric and terrestrial digital elevation model (DEM) at 90 meter resolution.  This dataset was produced largely from the NOAA NGDC Coastal Relief Model product (version 4.1).  Data sources include NOAA Hydrographic Surveys and U.S. Geological Survey 3-arc-second terrestrial DEMs. In addition to the Coastal Relief Model data, some far offshore areas were supplemented with other USGS bathymetric data processed by DFG.  Vertical units (depths and elevations) are in integer meters.  The vertical datum for the bathymeric data is Mean Low Lower Water (MLLW) and the vertical datum for the terrestrial data is the North American Vertical Datum of 1929 (NAVD29).
    Purpose: Assess bathymetric depths and terrestrial elevations.
    Supplemental_Information: Please refer to the NGDC Coastal Relief Model product documentation for more information on data sources and processing.
