[Qgis-user] Running v.clean on a QGIS vector layer (Polygon) through Sextante

[SBL]

Hi Paolo

Thanks for the swift reply!

Sounds sounds really good.
What I did not understand completely was: Do you mean that the default
settings of v.in.ogr are being used (snapping disabled and min_area set to
0.0001) or is the topology cleaning completely disabled in the v.in.ogr-part
of Sextante?

The cleaning of v.in.ogr can be enough in many cases, I might guess. While
building a propper chain of v.clean steps (with functionallity comparable to
cleaning in v.in.ogr) is a bit more challanging, especially for people
without experience in GRASS...

So maybe importing and exporting to and from GRASS could be used to perform
a quick, simple and beginner-friendly "lightweight-cleaning"?

I see this also as a solution for  Bug #2921
<http://hub.qgis.org/issues/2921>  , which furthermore offers additional
quality checks...
Actually, before I learned about the possibility in Sextante I considered
creating a plugin for that...

Cheers
Stefan
