Some of you may recall that I've previously advertised a tool that checks addr:postcode tags in OSM UK against the official Code-Point Open data. There are two reports:
* http://robert.mathmos.net/osm/postcodes/osm-errors.html is updated daily and flags up OSM postcode values that don't exist in Code-Point Open * http://robert.mathmos.net/osm/postcodes/location-errors.cgi is updated roughly weekly, and flags up OSM objects with postcodes whose location differs significantly from the postcode centroid in Code-Point Open. I've just discovered a bug in the first report, that meant many non-existent units were not being reported. (I'd forgotten to clear the cache of valid units between each sector). Having fixed this, there are now rather a lot of new errors (over 1500) there that could do with manual checking. Presumably some will be typos by mappers, others will be errors in sources, some will be old now-disused postcodes, and some may be new codes that haven't made it into Code-Point Open yet. If anyone fancies helping out, then please have a look at some of the flagged postcodes at http://robert.mathmos.net/osm/postcodes/osm-errors.html#unit and see if the OSM data needs correcting. (Remember to only use acceptable OSM sources for postcodes. Code-Point Open can be used, but address look-up tools from Royal Mail and others cannot.)
