The HDF5 driver has been recently updated to improve metadata management: http://trac.osgeo.org/gdal/changeset/22517 http://trac.osgeo.org/gdal/ticket/2412 The problem you are experimenting should be fixed in trunk but you need to re-build GDAL from sources to get it. regards -- Antonio Valentino _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
