Hi Andrea and Jim,
Just browsing the GRASS mail of the past month, I am sorry for
the late reply.
I have been working on ERS-1 imagery but I have not tried to do
anything with it in Grass yet. How did you import that data
into grass? I was recently thinking of trying this and any
help you could give would be greatly appreciated. It's great
imagery, don't you think?Jim
jim@sar_ws.fb4.noaa.govI wrote a small C program that cuts windows out of the ERS data
and re-writes it in a format readable by r.in.ascii. If you are interested
I can mail it to you. It works for images in the PRI format (that ESA
calls "SAR precision image"). If you have data in other formats, I cannot
help you directly, but you would have to contact ESA and ask for the
specific documentation where your file format is described...
I have written two short GRASS programs reading ERS-1 images in CEOS format:
one for SLC products, the other one for GEC or GTC products. If you like,
I can send you the program code.
What I still have to do is writing a program that reads PRI products in
VMP format. If that is what your program does, Andrea, I would be very
interested.
All the best
Olaf
