I'm trying to download some buildings from Overpass Turbo. Most of the buildings have a unique address which is tagged on the way of the building, but few of them have multiple addresses as a node (either randomly inside the building or as entrances). e.g. https://www.openstreetmap.org/way/45772548
How can I retrieve all the addresses associated with them? I've read that I should do reverse geocoding with Nominatim, but I can only retrieve one address for a given coordinate.
After digging multiple hours into the docs, I've found a way:
[out:json][timeout:25000]; ( way(45772548) -> .building; foreach .building { map_to_area -> .building_area; // Filter addresses node by excluding node with name (so amenity, tourism, leisure, etc.) node(area.building_area)["addr:housenumber"][!"name"] ->.addresses; foreach .addresses { convert associated_addresses "__associated_id"=building_area.u(id()), ::=::; out geom; } } ); .building out geom; Live: https://osm.li/Hgb
It can probably be optimized, but I'm not experienced enough.
