      Abscissae (x-coordinates) are specified to the nearest 0.000512
      Ordinates (y-coordinates) are specified to the nearest 0.000512
      Planar coordinates are specified in meters

       

      The horizontal datum used is D_North_American_1983_CSRS98.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257222.
