  Description:
    Abstract:
      These data were collected by the National Ocean Service
      (NOS, formerly the U.S. Coast and Geodetic Survey) for the
      purpose of charting the coastal waters and navigable
      waterways of the United States.
    Purpose:
      Provide geophysical data for general public use.
    Supplemental_Information:
      The data are an historical file and do not reflect
      corrections or supplemental information from NOS or other
      sources. They should not be used for navigation.

DATA_QUALITY_INFORMATION


  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      XY coordinates were recalculated for the new map/coverage
      created by the transformation process.
      The depths were calculated by taking the arithmetic mean of
      the depth values in the NOS Hydrographic Data Base that
      were found within the size of the cell (15-seconds). The
      mean depth is positioned at the center of each cell.
      Depending on the distribution of the depth values within
      the cells, this centering may cause apparent shifts in
      bathymetric features.

    Process_Step:
      Process_Description:
        There were three major steps in the production of this
        map/coverage:
        1. Creation of point coverage
        2. Transformation
        3. Add XY coordinates
        STEP 1. Creation of point coverage The
        data set used for this step were XY coordinates stored in
        .txt file format from the National Oceanic and Atmospheric
        Administration (NOAA), NOS Hydrographic Data Base. This
        data set also included depth values measured in meters.
        STEP 2. Transformation All
        positions were transformed from the geographic coordinate
        system (GCS) NAD 27, spheroid Clarke 1866 to GCS NAD 83,
        spheroid GRS 1980.
        STEP 3.
        XY coordinates were recalculated for the new map/coverage
        created by the transformation process.
