You could try to make a VRT from all your photos. It will be seen as a single GDAL dataset, and will take care of the burden of opening the underlying photos when needed. You can use the gdalbuildvrt utility to create the VRT from the photos. > > Thanks, > > Paul Meems > The Netherlands > _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
