That's what I posted in the Land Reg link. :-) Rob p.s. What I have in my mind is to grab each months data release from land registry (thus building up a good database of address + postcode), and then have some tool to visualise where we can match OSM addresses (without postcode) to these land reg addresses (with postcode). I could code a database but my tech skills don't go much beyond that :-( On 27 August 2012 23:59, Shaun McDonald <[email protected]> wrote: > Hi Rob, > > Postcodes are a bit more complicated.
