Finding objects of a special type for a given region

Is there a possibility to locate e.g. all ports existing in the US?
For example using geocoding of a POI layer?
Any help is more than welcome.

Hi Uta,
depending on the specific usecase and the APIs you are supposed to use I could imagine several approaches:
- Within xData2.SegmentsBySurroundingPolygonRequest you can locate all segments of a specific SegmentType (COMBINED_TRANSPORT) within a given rectangle. You may have to filter the result for BOAT.
Disadvantage: there's no country filter available for this approach - but maybe you don't need it 
- some of the response elements are RAILWAY STATIONS which you may have to filter on client side
- Within PTV Developer's Places Search there are some categories that might match some "port" criteria in their id, description or name. Use them to search within the area.
But: please be aware that the purpose of our APIs is not to extract data on client side. Therefore we do not support such techniques
