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.

Local maps showing potential issues to survey

Generate a map showing possible issues with OSM postbox or post office data in a limited area. The area will be centred on the postcode entered, but may cover more or less than that postcode region. The data is fixed from the initial postcode, and so won't be reloaded as you move around the map, but if you click the 'permalink' the refreshed map will show data centred on the current location. Once on the map, you can also obtain a GPX file of the postbox issues for download, which may be useful to those wanting to survey the problems.

Enter first half of postcode:
