Another Overpass QL question. I'm using Overpass Turbo and trying to realise the following query:


I'm trying to get nodes with a certain tag that are connecting two ways. The nodes should be filtered out, if both of these ways are not corresponding with a set of tags. So both ways can have unequal values of the same key, but have to be defined in the given set. Ways with the same tag shouldn't be discarded.


I want all nodes that have the tag barrier=lift_gate. These nodes should connect at least two ways, which are tagged as highway=living_street or highway=residential. (So that ways with tags like highway=service or highway=track should be discarded).

Thanks in advance!

Filtering based on counting something is outside of the scope of Overpass API (as of today), so a bit of post processing is required.

The closest way I could think of is the following: for each barrier=lift_gate node in a bbox, we first print the OSM node id, followed by the number of OSM ways, which are either living_street or residential. As an example, this query will return node 304989602 with two connected ways. Your task would then be to filter out node ids with less than 2 ways, which could be done in Excel or LibreOffice.

Thanks again :) I said "at least two ways" and I meant two or more ways. I don't want to count the ways, so if it is problematic I would be very happy for a solution that simply gives all nodes with "barrier=lift_gate" and if there are ways that this node is connected to they should be part of the given set (residential/livingstreet) (should I open again a new question? ;)) A out of the box solution on Overpass would be really great! Anyway great work, I appreciate it!
