Is GDAL capable of creating a TAB file?
Not currently. It can read them, and it is used in a few drivers such as GTiff. Writing is done only in the MapInfo TAB driver for the vector part.

Well, I don't know MapInfo limits with raster files. Perhaps is it just big raster dimensions that cause problem, or tiling, or .. ? > > Thoughts welcome, > Jonathan -- Geospatial professional services http://even.rouault.free.fr/services.html _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
