[Qgis-user] Error Delete Duplicate Geometries in QGIS v1.9

[Blumentrath, Stefan]

Hi Samuel

You could consider using v.clean from GRASS through Sextante.
We had a discussion about it a while ago (http://osgeo-org.1560.x6.nabble.com/Running-v-clean-on-a-QGIS-vector-layer-Polygon-through-Sextante-tt5050418.html). It should do what you want (if I understood you correctly).

Cheers
Stefan

Giovanni, the Tool is in Sextante Toolbox -> QGIS geoalgorithms -> Vector general tools -> Delete duplicate geometries (attached screenshot). This tool does not work in version 1.9 Master, but if it works properly in version 1.8.

Another question, is it possible to install the library LWGEOM in OSGeo4W?

Thank you Giovanni,

Samuel Mesa.

what tool are you talking about?
