Swiss Post – Postbox QA (Prototype)

This is an early QA prototype to support the maintenance of amenity=post_box data in OpenStreetMap (Switzerland).

No automated edits are performed.
Data from Swiss Post’s public location search is used for review and comparison only. OSM remains the authoritative record of on-the-ground reality.
