By the way, I forgot to comment that my computer is a dell,<br>
running vista 64 bits, with 6GB of run. I am also able to<br>
run grass (compiled for 64bits) under Ubuntu on same machine.<br>

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