The voronoi would work you would just need to clip the result against your building polygons. So you are clipping your voroni against the buildings so that only the bits of each voronoi polygon that overlap the buildings would remain.

Splitting polygons to only have one point in each polygon I've got a layer with building polygons and another layer with addresses. One building can hold several addresses and I want to split the building polygons so every resulting polygon only holds one address (I can live with some strange shaped buildings). I have come a part of the way by creating Voronoi polygons based on the address points and use clipping but my problem is that Voronoi polygons from neighbouring buildings may interfere with an actual building if they are to close: <http://osgeo-org.1560.n6.nabble.com/file/n5034081/Split_Buildings.png> If I could just limit the Voronoi polygon to stay inside the building polygon... Anybodý got an idea on how to solve this? I am by the way using the SEXTANTE modeller to create my own geoalgorithm doing this - it is a VERY strong tool and highly recommendable even if it is still a work in progress! ----- Regards Morten Qgis 1.8.0 Stand alone installer in Win7 64 bit -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Any-ideas-Splitting-polygons-to-only-have-one-point-in-each-polygon-tp5034081.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
