Hy community,
I´m currently working on my Master Thesis and I have to compute the "sky view factor". Since ESRI Arcmap is not a helpful choice to do that, I found that it is fairly easy to compute with GrassGIS (V.7) using the r.skyview command.
But I get an error message in the logfile i can´t really deal with. Hope that someone of you is experienced with that kind of problem and can help me out with this.
Here is what the GrassGIS output says:
