[gdal-dev] Urgent GDal failing to open a file.

[Courtney Schitka]

Frank & Martian

Thanks for your prompt replies.

If I know the coordinate system the file is supposed to be, is there a way I
can inject that into the file it's self ? Without needing to edit the code
or setting the GDAL_DATA environment variable ? The file is a GeoTiff ? I'd
provide a sample but the file is 100+ M could take a bit.
