[GRASSLIST:2434] Re: r.poly - linear features

[francesco.pirotti at unipd.it]

Did you try r.line ?  It creates vectors from thinned linear features (thinned 
with r.thin).  The command is under "raster->Extract vector map" whereas r.thin 
is "raster->analysemap->neighborhoos tools"

Hope it helps
