That is a Huge problem putting informations POI, Addresses on Areas. I addressed this on tagging a while back and was shot down that i should tag sufficient. But there are tons of problems with non-explicit route guidance. My solution/proposal was to have a route/nav-aid relation. If you want to reach Object A, with transport method B, you need to navigate to node C. Just to get an impression about the impact i am creating to 2 debug views (for myself and other interested partys) for parts of Germany. A problem in the countryside are long driveways, sometimes not mapped, tagged with random access tags or falsely tagged as tracks: https://osm.zz.de/dbview/?db=addresses-nrw&layer=routeable#51.63009,7.13605,15z OTOH in the dense urban areas you have the problem of Address for road A nearer to Road B. So you get navigated to the wrong spot on the road network. This view is generated with the OSRM Car profile and mapping all addr:* objects with the "nearest" function and comparing the highway name and the addr:street. If both are "filled" and non equal -> fail. https://osm.zz.de/dbview/?db=addresses-owl&layer=namemismatch#51.98848,8.49342,18z Just pan around and you'll easily spot horrible problems. The simple case its just at a corner. But there are a lot of cases where you end up significantly far away from the real address on a completely unrealated road. So yes - there are serious issues with the way OSM maps POIs and Addresses and their usage for navigation. Flo -- Florian Lohoff f...@zz.de UTF-8 Test: The 🐈 ran after a 🐁, but the 🐁 ran away
