I am facing the problem that wehnever trying to use geoprocessing tools like merge, dissolve, interesect and so on I am having big troubles with invalid geometries resulting in processing failures of the repective tools. I can then try to fix these errors with the quite compex algorithm of grass (v.clean) or manually adjust geometries but both is not ideal and too time-consuming. In the latests prereleases of QGIS 3 I found the tool "fix invalid geometries". However this tool also shows errors that it can´t run with inputs having invalid geometries.
Is there a algorithm that automatically fixes topological errors for users and/or is it possible that qgis processing tools will be more robust in handling invalid geometries. Especially the saga algorithms run even with invalid geometries which I think is desirable from a user-perspective -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Handling-of-invalid-geometries-in-QGIS-algorithms-tp5312231.html Sent from the QGIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
