Having just realised that gdal doesn't use proj EPSG file for reprojection (see my previous post on "Unsupported SRS but available in epsg file"), I have a few questions to clarify the reprojection processes both in gdal and mapserver : - where do the gdal gcs/pcs definitions come from ? Is it a separate repository or proj source files ? - Doesn't ogr2ogr use proj definition files at all ? Does this mean that an ogr2ogr reprojected file can be different than a mapserver reprojection result if proj/epsg definition and gdal pcs defs are slightly different ? - If I say "GDAL/OGR uses its own definition files to retrieve proj4 definitions and lets proj4 engine do the reprojection job", am I true ?
Thanks for these clarifications ! Regards, Guillaume _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
