So I am trying to use the r.denoise add on in GRASS 7.2.1 to remove noise from a .dem elevation model.
Initially when running the add on I received the error:
ERROR: mdenoise required. Follow instructions in html manual page to install it (g.manual r.denoise).
So I downloaded mdenoise.exe from the r.denoise page and added it to PATH in my environmental variables after placing it in a OsGeo4W/Bin and also tried putting it into the Grass 7.2.1 bin folder. Yet the error still persists...
I noticed that with Linux systems they recommend compiling the mdenoise from source. Should I have to install something like gg++ to compile and then try again? Or am I missing something obvious?
