Well normally, I need to search on the internet for all cities, provinces within a country. Then I search for that name on our site (openstreetmap), after that I click for suggestion to find the ID. My far purpose is to get Polygon of that region, from the ID by using this link: http://polygons.openstreetmap.fr/get_geojson.py?id=1903516 But I have a difficult time finding all ID. Is there any api to get ID of all cities (provinces) within a country, or districts within a city ? or a site that can do so ? asked 10 May '21, 04:32  LoiChau |
One Answer:
Have a look at Overpass QL, some examples might even fit your bill. Regards answered 10 May '21, 09:53  H_mlet |
Looks like this ID is just the relation ID of the administrative boundary: https://www.openstreetmap.org/relation/1903516
