[Talk-GB] GB postcodes

[Mick Orridge]

On the subject of postcodes, I have generated approximate regions from 
the ONS postcode data for postcode areas, districts and sectors which 
can be downloaded as shp files here:-

http://www.gismosoftware.co.uk/postcode-data.php

They are free to download and use under the ODbL license.

The generation method is detailed here:-

Please don't add these to the OSM database as they are not real objects, 
and are only an approximation.

I guess they could be made available as overlays in the same way as the 
postcode points, I'll investigate when I get a few spare minutes!

They could also be used to check for incorrect postcodes held in the OSM 
database e.g. an NE postcode found in the NG postcode area would almost 
certainly be incorrect but care would be need near the polygon edges as 
a DE postcode just within the NG area may well be correct due to the 
generation method.
