Tag:boundary=exclave

An exclave is an isolated part of a territory that is surrounded by one or more other alien territories. [1]

Tagging exclaves as separate relations is useful if you have metadata for individual exclaves. This could for example allows users to search exclaves by name or number, and query which exclave a particular point in space belongs to.

How to map

Create a relation with tags type=boundary and boundary=exclave. Use outer for the border between the exclave and alien territory. Use inner for any counter-enclaves. Set other tags on the relation store useful metadata about the exclave, e.g. ref=* for a reference number or name=* for a name.

Example: Baarle

In and around the town of Baarle near the Dutch-Belgian border, Belgium has 22 exclaves and the Netherlands has 8 exclaves (7 of which are counter-enclaves). All these exclaves have reference numbers, stored as ref=* on the exclave relation.

Tagging exclaves is better than tagging enclaves

• boundary=enclave

If you know places with this tag, verify if it could be tagged with another tag.

An enclave can always be tagged either as boundary=exclave (if the enclave belongs to a larger territory) or as boundary=administrative (if the enclave itself is the entire territory), so boundary=enclave is never needed. Conversely, not every exclave is an enclave (if the exclave is surrounded by more than one alien territories). Therefore tagging with boundary=exclave is superior to tagging with boundary=enclave.
