To create virtual nodes at the same position as another node

Node - position

Status: Proposed

Node relations are used to create a virtual node at the same place as another existing node. They can have only one member, a node. This datatype is useful when mapping several distinct objects at the same position, where all those objects are represented only as node. With this relation you can have several point objects at the same spot without using multivalues or overlapping nodes.

Layering

Usually you will add layer tags to the objects at the same position (node member and the relation itself) in order to define real world stacking.

Roles, tags and members

  • The tag to define the relation is type=node.
  • These relations should have only one member. You can omit the role or name it something like position.

Examples and Usecases

A usecase could be a pole with several traffic_sign=* attached to it (or also other poles where you would want to tag several distinct objects attached to them). Another usecase are trees with stuff attached to them, or a pole with different antennas attached.
