Status: in use

A site relation can be created to group detached parts of a building together.

This is required so that entrance=* nodes, barrier=gate nodes, and amenity=loading_dock nodes can be assosiated with the correct building, if they aren't connected to the building outline.


  • Map the building as a way Way, and any entances/gates/loading docks as node Nodes
  • Then create a relation tagged with type=site and site=venue, which includes the way and the nodes


  • relation 13734823 This building has several entrances and loading docks. The only ones that are included in the relation are the ones that are not connected to the building outline.
  • relation 13737217 The gates of this stadium are not conntected to the stadium landuse, so the relation is required to group them together.

Alternative Tagging Methods

  • The is_in=* tag is declining in popularity, and breaks if the name of the parent feature is changed.
