Post Hoc — Analysing UK OSM Postbox Data

OpenStreetMap records the location of postboxes using the amenity=post_box tag. 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. For further information, please see the Technical Details page.
