Hi All, People from the Technical University Delft have created an automated way for: "Validation and Automatic Repair of Planar Partitions". It is called 'pprepair'. I'm not 100% sure it fixes your problem, but as a commandline tool it is pretty easy to run. It's pure c++ but has cgal as dependency. On debian it was 2 minutes to build and run. Code is here: https://github.com/tudelft-gist/pprepair Some theory: http://www.gdmc.nl/ken/files/12_osgis.pdf And Barry blogging about it: http://geospaced.blogspot.nl/2012/09/fixing-polygons-with-pprepair.html If interesting, have it a go. Regards, Richard Duivenvoorde ps actually I promised the TU people to write a simple qgis plugin for calling it in a separate process (like we do with gdal commands), so if you are on it..... _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
