These are fantastic news, thank you for sharing.
It would be great if radiometric calibration of Radarsat-1 data could be included in SNAP.
Well of course it can, provided the operation is well documented!
I ab sure about the technical part. What I was trying to say: By now, the number of people using Radarsat-1 data was comparably small because the data were not openly available and the mission has ended, so that the functionality was not profoundly missing in SNAP. But now that the access has been granted to everyone, this might experience a huge boost.
