Hello. There are cities without relations. 'Search results' shows path of relations. How to get relation_ids from this path? For example I am looking for 'Wislon'. In Search results I see City: 'Wilson, Wilson County, North Carolina, United States of America', ie Wilson is part of Wilson County and Wilson County is part of North Carolina and so on. If I go to the details of the city (click the link), at the bottom of the page I see there is no any relation. How can I get relation_ids for Wilson County, North Carolina, United States of America? Usually I use http://www.openstreetmap.org/api/0.6/relation/relation_id, but this is not the case. As I can guess, this path is based on latitude\longitude of a place, and map\engine checks the next bigger territory untill the country level is reached. Is there any API call which I can use to get relation_ids of this tree? Thank you. |

The county relation is available: http://www.openstreetmap.org/relation/2528757 To obtain the county relation from another object, you could synthesize a coordinate for the object (maybe the center or use some method to select a child node) and use reverse geocoding to obtain the admin hierarchy for that point. Nominatim and Overpass API both have support for such queries: http://wiki.openstreetmap.org/wiki/Nominatim#Reverse_Geocoding http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Query_for_areas_.28is_in.29 1
Your information + some additional search + re-read few times Overpass API (lack of examples) and I have finally what I want :) Nominatim is cool thing, lots of example, but lack of functionality :) Here is the example of the solution: http://overpass-api.de/api/interpreter?data=rel(4084902);>;is_in;out; Also related info: http://help.openstreetmap.org/questions/20053/locating-an-osm-object-eg-finding-town-relation-name/20055

Alternatively, you could go to http://nominatim.openstreetmap.org. Search for Wilson, pick the one you want, click on details and you get a page like http://nominatim.openstreetmap.org/details.php?place_id=144418235 On that page you will find all the links of the relations used by Nominatim to calculate the address. Wow. This method is also cool. Is there any way how can I get the data from details page via API?
