How to query for adjacent admin boundaries?

0

After hours of internet sleuthing and more-error-than-trials on overpassturbo, I admit defeat and ask for help. Here's the thing: I'd like to..

  1. take a given coordinate as input
  2. get its corresponding administrative boundary (admin_level=6) node
  3. to (2), give me all adjacent (as in: bordering on) admin boundaries

Any idea how this could be accomplished? I found the "around" clause but couldn't get it to work either.

Any help is greatly appreciated!

  1. Check out the 'is_in' command. 3. admin_level boundaries should be all relations so 'recurse' back up from your found boundary to the ways it's attached to & search those ways to see if it has any other associated relations.

Thanks for the tip, but I'm a bloody noob on the whole OSM thing. Would you (are anyone else watching) be willing to write some example code (overpass would be best for testing purpose) on this?
