I don't know if someone is currently working on the JAXAPalsar driver. Anyway I' very interested in extending driver for SAR products to get more metadata so I would be happy to help if you need. Palsar products are in CEOS format so IMHO it would be nice to setup a general mechanism to decode CEOS records (a similar job has been done for ENVISAT records recently) http://trac.osgeo.org/gdal/ticket/4105 http://trac.osgeo.org/gdal/attachment/ticket/4105/asar_metadata.patch The hard part (it is a very boring job) IMHO is to fill data structures that properly describe CEOS records for each sensor end product type. Anyway populating record descriptors is a job that can be done gradually and, hopefully, with the help of other users so we could start with the few metadata you are currently interested in and add other record descriptors later. The key is to setup a genereal (enough) framework for CEOS record decoding.
