      Planar coordinates are encoded using row and column
      Abscissae (x-coordinates) are specified to the nearest 29.986231
      Ordinates (y-coordinates) are specified to the nearest 29.986231
      Planar coordinates are specified in meters

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
