ELCOVSION 10 requires the WI codes 11, 81, 82 and 83. The coordinates are converted to a right-handed coordinate system:

  • Point Number (WI 11)
  • Easting (WI 81) = X axis
  • Northing (WI 82) = Y axis
  • Elevation (WI 83) = Z axis

The points are inserted as full control points into the ELCOVISION 10 object point list.
