Hi Christian, thanks for fast reply!
I also tried r.mapcalc with eval(), setting variables for dir_x/dir_y. But map[ , ] does not take them with the same error.
Looks like I have to find another way to fasten the if-procedure
in order to make a r.water.outlet on many many areas at the same time.
Cheers, Achim _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
