[Gdal-dev] Problems with RS2 driver for import to grass

[Benjamin Deschamps]

I'm having a few issues importing RADARSAT-2 data to GRASS. I used:

r.in.gdal
input=RADARSAT_2_CALIB:SIGMA0:/Users/Benjamin/Desktop/PK6621_DK406_FQ9_20080405_124900_HH_VV_HV_VH_SLC_(Altona_Promo)/product.xml 
output=altona

to import the sigma nought calibrated data. For some reason this only
imports 31 GCPs out of 350, and the values of the resulting GRASS layer are
limited to -1, 0 and 1, so the map doesn't look like anything
understandable. If I import uncalibrated values instead
(RADARSAT_2_CALIB:UNCALIB:etc) I get a much more appropriate range of
values, and all 350 GCPs are included.

How can I get all GCPs and a more appropriate range of values for the sigma
nough subdataset? The dataset is available as part of the RADARSAT-2 demo
dataset at 
ftp://ftp.mda.ca/Fine%20Quad-Pol%20Dataset/Altona_%20R2_FineQuad9_HH_VV_HV_VH_SLC.zip
ftp://ftp.mda.ca/Fine%20Quad-Pol%20Dataset/Altona_%20R2_FineQuad9_HH_VV_HV_VH_SLC.zip 

Thanks, Benjamin
