      False easting: 23500000.000000
      False northing: 0.000000

      Planar coordinates are encoded using row and column.
      Abscissae (x-coordinates) are specified to the nearest 600.000000.
      Ordinates (y-coordinates) are specified to the nearest 600.000000.
      Planar coordinates are specified in meters.

      The horizontal datum used is D_Krasovsky_1940.
      The ellipsoid used is Krasovsky_1940.
      The semi-major axis of the ellipsoid used is 6378245.000000.
      The flattening of the ellipsoid used is 1/298.300000.
