[gdal-dev] Injecting Projection information in CreateCopy

[Christiaan Janssen]

VRTDatasets seem to be the best way to go in this case. Is there by chance a way to build a VRTDataset that is an exact copy of a GDALDataset or do I need to do it manually (not a big deal if I do). BTW, Thanks for all the help.

I would take a look on how gdal_translate process the "-a_srs" 
parameter: 
http://trac.osgeo.org/gdal/browser/trunk/gdal/apps/gdal_translate.cpp#L311

The best example of what I'm doing is trying to create a GeoTIFF version of a standard TIFF (ie create a full raster copy but with GeoTIFF tags for the projection and transform embedded), at the same time not limiting myself to only outputting to a GeoTIFF format but other geospatially capable formats as well (ie NITF, Erdas Imagine, ...) some of which only support the CreateCopy function.
