Those 700 XMP and 33723 IPTC tags are not handled by the GTiff driver neither in read nor in write mode, so that explains why gdal_translate doesn't copy them. You could probably try the 'tiffset' utility to set them afterwards. Or hack geotifcp.c to add support for those 2 tags. The tags[] array looks like an interesting place where to hack that in. > Greg > _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
