    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • G-polygon (1)

    2. What coordinate system is used to represent geographic features?

      The map projection used is NAD_1983_UTM_Zone_10N.

      Projection parameters:

      Planar coordinates are encoded using coordinate pair
      Abscissae (x-coordinates) are specified to the nearest .000512
      Ordinates (y-coordinates) are specified to the nearest .000512
      Planar coordinates are specified in meters

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic ReferenceSystem 80.
      The semi-major axis of the ellipsoid used is 6378137.
      The flattening of the ellipsoid used is 1/298.2572222.
