Hi, I would like to raise attention for an issue which was discussed in length in the qgis-users list [1]
You can ignore the beginning of the discussion where I mixed up "Split parts" and "Split features". The split features tool does not produce valid geometries. This can be easily reproduced by splitting one part of a multipart feature and then try to split that part again (or save and check the feature with e.g. postgis' st_isvalid()). This goes hand-in-hand with the comments in a related, older issue [2]. This makes the workflow much more complex [see 3], if you want to have a valid output at the end. The discussion ended in a new Tool in the DigitizingTools (0.11.0) plugin (thank you Bernhard), which acts much more intuitive from a users' perspective. - singlepart features are split and one half inserted as a new feature - multipart features are split and the user has to choose which part gets inserted as a new feature, while the other half stays a multipart feature with all other parts still connected This raises the question if and how to get that to replace the core tools. Happy for any input :) cheers Andreas [1] http://osgeo-org.1560.x6.nabble.com/Split-features-tool-behavior-td5321288.html#none [2] https://issues.qgis.org/issues/12799 [3] http://osgeo-org.1560.x6.nabble.com/Split-features-tool-behavior-tp5321288p5322315.html _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
