KB10820 - How to convert coordinates from WGS84 to the Irish National Grid coordinate system

Reprojection of points from WGS84 to the Irish National Map Grid is performed as follows:

  TGIS_CSCoordinateSystem cs_wgs = TGIS_CSFactory.ByEPSG( 4326 );
  TGIS_CSCoordinateSystem cs_osni = TGIS_CSFactory.ByEPSG( 29901 );
  ptg_wgs.X = -2 ;
  ptg_wgs.X = 60 ;

  ptg_osni = cs_wgs.ToCS( cs_osni, ptg_wsg ) ;
