[Talk-GB] New postcode overlay

[Chris Hill]

I have updated both the Codepoint Open [1] and ONSPD [2] postcode tiles 
which can assist with . The open data from OS has changed from 
Address-Point which was discontinued last year I think. The new source 
is the Postal Address Location Feed of Geoplace. This means some 
postcode centroids have moved. Most differences are small but a few are 
infeasibly large.

I have also created a new map overlay [3] showing the postcodes that 
have been added recently. This will help people find places, such as new 
developments, that need a survey. Any feedback would be welcome. If it 
is useful I'll update it each time a new version of the open postcode 
data are released.

I'm working on including an overlay that shows postcodes that have 
recently been retired too.
