hi @odadoun

thanks for your interest. In your question you've got two unique codes for Rostock:

• 13003 is the city of Rostock (Stadtkreis in German)
• 13072 is the Rostock's regional area (Landkreis in German)

Then, for each of them you've got two shapes, screenshots taken from my notebook

• Rostock Landkreis is divided between the mainland, and a little island

• Rostock city has two polygons, but one is actually an estuary/water body (took a screenshot from my notebook, setting alpha to 0.2 for better visualization)

See OSM for more detail https://duckduckgo.com/?q=rostock&t=newext&atb=v247-1&ia=maps&iaxm=maps
