Post Hoc — Analysing UK OSM Postbox and Post Office Data

OpenStreetMap records the location of postboxes and Post Offices using the tags amenity=post_box and amenity=post_office respectively. The Post Hoc tool provides statistics, reports and maps to compare the data in OpenStreetMap with data from Royal Mail and from Matthew Somerville's former 'Locating Postboxes' webapp. The Royal Mail Post Box data comes an FOI request. The post box list originally came from the list of Post Office locations compiled by Edward Betts from Royal Mail's Post Office Branch Finder. For further information, please see the Technical Details page.
