Hi Markus,
What I'm trying to do is start with a raster stream map from r.drain and
convert it to a sequence of vector points, where each point has information as
to its position along the stream. I then use the points for sampling a stream
profile and related information. Oddly enough, with

simulation which takes a lot of user inputs. I do not want to go through wxGUI
as the user is not interested in options shown by its GUI. Is there any

Hello Michael
You could use r.stream.order after r.stream.extract to get your stream
network ordered, and then, after running r.thin on the ordered stream
network, convert it to vector using r.to.vect with the -v flag, that way,
each order is a cat, you can them use v.to.points or the add-on
r.stream.extract can make the raster streams—ones that are pretty much
equivalent to those made with r.watershed. But it can’t do stream profiles
AFAICT. Also, like r.watershed, it extracts a stream network, not a particular
stream. That is why we’re using r.drain to extract a particular
I saw this but apparently it is not available for GRASS 7.

Hi,
I am trying to append points to a new map patch_map6.
v.patch -e input=patch_map1 output=patch_map6
When I run the above command I get the following error.
ERROR: Key column not found
I don't know which column it is looking for.

Hi,
I receive the following error on importing an ESRI binary grid file into
GRASS 7.
I guess that the error can be ignored as the imported file type is float32
so there is no .vat file? I'm not sure if related to GRASS or GDAL?
Cheers,
Richard

I tried to install v.profile under GRASS 6.4.4 to see if it would work but it
failed to compile.

it is as I wrote it for grass 7.
