Hi, Thanks for the great tool you give us with the OGR library.
I actually meet some problems with a specific coordinate transformation : I need to transform coordinates from the NTF Lambert II Etendu system (EPSG:27572) to WGS84 (EPSG:4326). When I 'simply' transform a shapefile with ogr2ogr in the WGS84 system, I get shifted geometries, compared to trusted sources. After some inquiry, it appears that an additionnal transformation is needed (a geocentric translation). Is there a way to handle this transformation with the OGR API ? The EPSG registry contains a coordinate transformation (EPSG:15939) which seems to handle my problem : is-there any mean to use it with OGR ? Best Regards, -- Alexandre Gacon Sent from Paris, France
