I'm afraid I know very little of the subtleties of Erdas overviews, but I see that the HFA_USE_RRD config option can also be set to YES and produces a .rrd file. Perhaps this is was you are looking for. See http://gdal.org/frmt_hfa.html . I've found also a past thread where this is somehow discussed : http://www.mail-archive.com/gdal- d...@lists.osgeo.org/msg00129.html _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
