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

[Martin Chapman]

Yes, I would try Frank's suggestion first though.  If it doesn't work then you could re-write the file and assign a projection with create() or createCopy() on the driver object..

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.

 I write you with kind of an urgent problem today. The company I am doing some consulting for is using GDAL to read a majority of their data. They just purchased 800$ worth of some GeoData from a third party company. Everytime we try an dopen the data through Gdal I get. A problem with trying to create a Coordinate Transform. See error
 
 ERROR: No PROJ.4 translation for source SRS, coordinate
 
 When I did a Gdal Info on the file. I find this information out
 
 Coordinate System is:
 PROJCS[,
    GEOGCS["unnamed",
        DATUM["unknown",
            SPHEROID["unretrievable - using WGS84",6378137,298.257223563]],
        PRIMEM["Greenwich",0],
        UNIT[,0.0174532925199433]],
    UNIT["unknown",1],
    AUTHORITY["EPSG","0"]]
 
 
 Which I think is the root of my problem. Is ther ea good/easy way for me to fix this ? quickly ?
 
 Court,
 
 I *suspect* GDAL is failing to find it's supporting coordinate system
 files.  Try setting the GDAL_DATA environment variable to point to the
 directory with the files like pcs.csv and ecw_cs.wkt.
 
 It would also be helpful if you were able to indicate the file format
 with the problem, the version of GDAL, and ideally a sample file.
 
 Best regards,
