Hello,
I tried this command:
r.terraflow.short -s elev=world_dem4 filled=world_dem4_filled dir=world_dem4_mfdir swatershed=world_dem4_watershed accumulation=world_dem4_accu tci=world_dem4_tci memory=1000 STREAM_DIR=/home/faroux/ --overwrite
(world_dem4 is the gtopo30 dem)
the first filled, dir and swatershed seems to well end; but when arriving at accumulation ant tci, there are a lot of messages:
warning tci has negative values
And when i draw it, there are many, many negative values everywhere.
Anybody can help me?
Thank you
Stéphanie
