[GRASS5] ERS-SAR import with r.in.gdal

[Markus Neteler]

Hi SAR lovers,

I have modified the r.in.gdal to properly assign GCPs read
from the CEOS SAR dataset to GRASS conventions. So far working
for SAR data taken in decending pass. However, I don't know
how to re-order in ascending pass since I don't have
such a dataset.

I there someone out there who could provide me such a dataset
for testing (ERS SAR ascending pass, usually taken in the night time)?

Additionally r.in.gdal now optionally re-projects the input GCPs
to a user defined projection (the user simply specifies the target
location to read the projection info from).

Not yet in CVS, but forthcoming,
regards
