Hi list members,
with the help of Markus I managed to add the r.usler module to my GRASS 6.4 RC1 installation.
I tried the modul with some of my precipitation data and I figured out that only the first option (roose) for the methods is working. Also the result I got is strange...
Please have a look to the attached jpg. The grey triangle is the result of r.ulser, in color the precipitation data. Calculation region is the other half of the triangle
Thanks,
Christian
