I'll start studying how to write a GRASS module in Python in the next days and at the same time I will keep on testing the procedures so as to show you some results and fix some open points. > > Something else you should probably do during this bonding time is to > elaborate a schema of your algorithm, so that it is easier to understand > what it does at each step. > Yes, this could be very useful also for me in order to better organize and put in order everything! > > Best wishes, > Moritz > Thanks again!
