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

The upper computational limit of r.watershed and r.terraflow (not 100%
sure here, may be higher) is 2,147,483,647 cells. It will take a long
time, r.watershed -m much longer than r.terraflow, but both modules will
do it. It will be many hours if not some days for a region with

What exactly is wrong with topology? The existence of these dangles?
note the v.strahler help page makes special mention that if you used
r.watershed you should check the topology. Maybe it makes a bitter deal
out of that than is really the case?

I've loaded a vector map (MIF/MID format), then created a thematic
vector map layer (area) via d.vect.thematic GUI window (Output legend
for GIS manager is ticked; save thematic commands is ticked). I've

Hi,
I am trying to make a map of points from a CSV file. I have imported the
file using v.in.ascii and the map displays correctly. My problem is that it
uses a different coordinate system than another map that I am trying to
incorporate it with. I tried to reproject the point map to my other map

Hi Markus,
thanks for your answer. I found that the problem is in the topology of
the river network. I think that v.strahler produces many '0' because it
finds many little 'circles' in the stream vector. I tried to produce the
stream network both with r.watershed - r.to.vect and with

Hi..
If I well remember, the problems of 0 values in the category data were
related to braiding or similar artifacts deriving from rasterization
process
r.strahler used with threshold not too small should clean network and
solve the task...

That worked. Thank you so much I have been working on that for a few days
now (I am still very new to GRASS). I appreciate the help.

Hi Jarek,
Thanks for the reply! What you means by lots of time? Many hours, many days

Any comments about Windows vs Linux?

Dear all,
I have tryed to use some d. series on my windows
grass versions (stand alone, or compiled under msys)
and I perceived that I can't do that (I am not talking
about -wx, but -text and -gui).
It is possible run d. series of commands under windows?
