Pub Density on OpenStreetMap

OpenStreetMap data for Great Britain were downloaded from Geofabrik on 22 Jan. 2011, uploaded to a PostGIS database using osm2pgsql. Nodes and Ways tagged with amenity=pub were assigned to centroids of 5 km square grid based on the Ordnance Survey National Grid and the number of pubs in each square counted.

 

The grid was generated, pubs counted, and output generated using Quantum GIS.
