I used OSMAnd for editing this and forgot to frequently upload the changes. So this is kind of an accumulation of all my changes over a quite long period of time.

Sry,
i was using an old JOSM-Preset for the Imagery. But I used the GSI seamlessphoto Imagery indeed. The GSI Imagery is from December 4th 2018; Digital Globe according to my research only from April 25th 2018. Because of the relatively new GSI imagery I started mapping the region recently.
sincere regards edtha!

Da hab ich irgentwelche Werte falsch eingefügt, hab das wieder korrigiert. Aber trotzdem danke für das schnelle Melden.
