OSM and OSL differences tileset
The OSM and OSL differences tileset is a tileset available for use as a background layer while editing in the UK. It highlights differences between the OS Locator data set of UK street names, and the street naming we have in the OpenStreetMap database.
This is created and maintained by ITO World based on the OS Locator boundaries of roads. Any ways not found in OSM are marked on these tiles as a bounding box encompassing the missing road. These tiles can be used as a background layer in Potlatch and JOSM.
More information is available on an ITOworld blog post about it
The OSM and OSL differences analysis tool gives stats by borough based on the same differences analysis.
A comma seperated .csv file of the changes from release to June 2011 is available here.
