I maintain an unrelated (not geo) software package, and there my practice is not to engage in debugging old versions. It takes a lot of time and in the cases the problem has been resolved already, it is entirely not useful (to the project). I am not saying NAD83 is better specifically if you udpate. I really don't know. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
