Dear all,

I am organizing a very large DEM for a region of interest,
and would like to know from our colleagues what is your
experience with features extraction from large DEM.
What was your highest (rows and cols) DEM that
you handled on grass? I will need to extract features
using r.watershed, r.flor, w.terraflor, and the I need
to extract several features (may be 10) from my final
(not yet ready) DEM.

Thanks in advance for the help
