Frederico, Available as ST_Snap in PostGIS (http://postgis.org/docs/ST_Snap.html), that relies on GEOSSnap : http://geos.osgeo.org/doxygen/geos__c_8h_source.html Would be easy to add in OGR geometry class as well (relying on GEOSSnap) Even -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
