I am trying to generalize a polygon layer using the v.generalize algorithm in QGIS 2.14. While it works for linear features, polygon features are refused by the program. Might anyone know, what the specific problem in this case is? The Data is referenced in DHDN GK 4.
I don't want to do the workaround using linear features, but rather would like to directly generalize (chaiken) the polygon features.
