[GRASS-user] inverting DEMs

[Bulent Arikan]

Hi,

I am trying to invert a DEM (i.e., make peaks basins and vice versa) but
there does not seem to be a module for this. I am assuming this can be done
through ' r.mapcalc ' which I have very limited experience.

I also want to get ' r.prominence ' from the Add-ons site but the
text file is not downloadable. Should I copy and paste to create a text
file that contains the script?

Thank you for all the suggestions,
