  6. How does the data set represent geographic features?

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

      Indirect spatial reference:
      None

      This is a Vector data set. It contains the following vector data types (SDTS terminology):
      • GT-polygon composed of chains (129)

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

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 2e-008. Longitudes are given to the nearest 2e-008. Latitude and longitude values are specified in Decimal Degrees.

      The horizontal datum used is D North American 1983.
      The ellipsoid used is GRS 1980.
      The semi-major axis of the ellipsoid used is 6378137.0.
