I'm not sure but from what I read in the r.stream.basins description,
you can have more than one point in your vector file in roder to
delineate your basins. Now, in case you have one basin inside another,
what I did once was:
1) get x,y coordinates of each point using v.out.ascii
2) for each point run r.watershed...
Yes, thats what I want as well, but I want to automatize it and not to run for
each
point manually. I also want to run
for each point a grass-function (not necessarily r.stream etc.)
I just want to know how it basically works to loop over points.
to things I thought:
1) loop over the ascii if that is possible
Here's an outline of a method I once used to get all points where a
stream network crosses a road, then loop thru those points to create
drainage basins for each of those points. Maybe you can distill from
this what you need.
