[GRASS-user] Export multiple rasters into a single textfile

gdal2xyz.py from gdal has a -csv switch
(Though never tested the -csv by myself, but the script itself works nicely)
It is not exactly what you want but might be a start if no one else
comes up with a GRASS solution.
should be doable to create a script that integrates gdal2xyz and
combines the values afterwards..

kind regards
