Hi, I've frequently stumbled upon the problem that several functions (like geomentry().intersection(geometry2), geometry().touches(geometry2) only return something useful if BOTH geometries have a vertex at the meeting point (which is inherited from GEOS)
My expection: they do intersect or touch if they share space. I am Getting: Only a result if they share at least a vertex. This results in tools like geoprocessing:intersection or clip giving strange/unintuitive outputs. Is it a design decision or just never discussed? It could be solved quite easily, (see https://hub.qgis.org/issues/14504#note-2) _______________________________________________ Qgis-developer mailing list [email protected] List info: http://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: http://lists.osgeo.org/mailman/listinfo/qgis-developer
