if you enter “Frankfurt” at https://maps.openrouteservice.org/ ist gives you the Results for Frankfurt/Main and Frankfurt/Oder (both in Germany). However if you select one of them, you get sent to the opposite one.
According to https://www.openstreetmap.org/note/1570517 where this has been reported first, the actual map data on OSM and whosonfirst ( see links in OSM-note ) is correct.
Can somebody please have a look at this?
Our geocoding is Pelias and the data in that case is not coming from OSM, but from whosonfirst. And indeed it’s wrongly tagged there! Good catch, I’ll put an issue to WOF.
Pelias doesn’t even find Frankfurt/main when looking for it explicitly! Only with a fallback and low accuracy. Which is in itself likely a Pelias issue.
