See http://www.epsg-registry.org/ -> retrieve by code -> 6326 -> "World Geodetic System 1984 ... Code: EPSG::6326 ..." -> View Like this you can look up these authoritative codes. In GDAL they are used in lookup-tables etc. Markus _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
