in the addon r.basin, the help says that basin output coordinates must
be picked up from some vector feature, the river network, which is
generated by the addon r.stream.extract.
That means I have the utm elevation raster and successfully ran
r.watershed for accumulation raster on grass70/win7.
However, despite the plugin get steps 1 through 4 without errors, it
cannot complete the area delineation.
I have tried, both, picking a utm point from point geometries and from
line geometries.
The message I get is:
–
An Error has occurred.
Please try with another pairs of outlet coordinates.

Please refer to [1] for detailed instructions on the proper way of inputting the coordinates into the module. The pair of coordinates should be similar as the ones used on r.water.outlet, you must tell the module where in the map is the outlet of the basin you’re trying to analyze.

maybe another issue (remembering I'm on grass7/win7) is installation
of dependences of r.basin: r.stream.stats r.stream.distance and
r.stream.order are missing because g.extension returns "File is not a
zip file" when trying to add them.
The rest r.stream.basins and r.stream.extract are present.
Could that be an issue?
Tks

C,
I'm picking them from the vector streams from r.stream.extract it comes up
from Grass picking points from geometry.
I dont know what 'near' means..
Thanks

Maybe you're picking the wrong pair of coordinates,
Are you picking them upstream from the basin outlet? I mean, near the
outlet but a little upstream

That is definitely an issue. You need to have all the dependencies installed in order to get r.basin working. What is the command line that gives you that error?

I’m not a windows user, this is also a reason why keeping the list cc’ed is a good idea. The problem you mention is in g.extension, not in r.basin, is windows related, and most likely has already been solved in more recent versions.

The message is misleading I'd say.
Current state:
- in GRASS GIS 6, r.stream.stats is an addon
- in GRASS GIS 7, r.stream.stats is in the core but commented due to
quality issues (need to be fixed)

Markus,
thanks for clarifying. Is that just a Windows issue or r.stream.stats (plus
other r.stream.*?) is missing on other platforms?
That's on all platforms for GRASS 7.0.svn. The code is there, it
"just" needs to be better tested and fixed as needed.
To start, compare it to what r.watershed calculates.
In grass 6 r.basin works well so its dependences.
So in grass7 as r.stream.stats (r.stream.order and r.stream.distance also?)
are not yet done and are not addons, r.basin will not work.
Right for 7.0.svn.
Could you let me know a schedule for fixing (or just in case other contact)?
Volunteers needed. Note that in *trunk* (GRASS 7.1.svn) all tools are
enabled. You may try that.
Markus
PS: If you self compile (not that hard on many platforms, see http://grasswiki.osgeo.org/wiki/Compile_and_Install ) then you can
just change into the respective directory and run "make" to get the
command compiled for testing if you are on 7.0.svn.
