6. How does the data set represent geographic features
   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):

      • Entity Point (1101)

   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 0.000002. Longitudes are given to the nearest 0.000002. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is D_WGS_1984.
      The ellipsoid used is WGS_1984.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257224.
