doing this operation the postgis/spatialite way is tricky because the st_split function won't work if you don't have a node/vertex where you need do the split. See for example this workflow https://mygisnotes.wordpress.com/2017/01/01/split-lines-with-points-the-postgis-way/ I had to use it (does not means that is the best way) to solve a specific problem here. I used PostGIS because in QGIS/Processing do not seems there is yet any tool (not even in external providers? I maybe wrong, I just could not find any) that allow do this operation. cheers! -- Giovanni -- _______________________________________________ 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
