[Talk-gb-westmidlands] [Talk-GB] UK Postcodes - Potential data source

[Andy Robinson]

In the meantime I'm just downloading the files and filtering in spreadsheet
for my patch (Sutton Coldfield) and then checking/adding postcode data for
the handful of addresses it contains for each month. Though this only really
works if you have the majority of your building addressing done for an area.

 

As I'm now adding some postcode data from this source I've added the
required attribution to
http://wiki.openstreetmap.org/wiki/Contributors#United_Kingdom

 

Incidentally, what do folks feel about adding any of the other data from the
dataset?:

.         the full address of the property (Primary addressable object name
(PAON), Secondary addressable object name (SAON), street, postcode, locality
(if available), town, district, county)

.         the price paid for the property

.         the date of transfer

.         the property type (Detached, Semi, Terraced, Flat/Maisonette)

.         whether the property is new build or not

.         whether the property is freehold or leasehold.

 

Cheers

Andy

I'd agree with Rob's logic and extend it to show one of three results:
postcode missing or postcode incomplete or postcode incorrect. We have loads
of addresses with only the first group in place e.g B27 and I'm sure when we
were using codepoint( before we knew it was dodgy in licensing terms) we
chose the wrong break point in address runs.  We currently have 61272
addresses in the W Mids and 44164 have postcodes.

This does indeed seem like a very useful data source. Great find!
 
However, I'm struggling to think of a nice way of visualising it to
make it useful. What I've got so far in my mind is:
 - Take an entry from the list
 - Take its postcode
 - Search for the postcode (I've got a curated list of postcodes as
part of my PostCodeFinder [1])
 - Get the location of the nearest match (hopefully, we'll find at
least a CV4-type segment match)
 - Search for roads within an x mile radius with a matching name
 - Associate that entry with that road

Hi Matt, 
I was actually thinking the other way round. That is:

Pull in a list of building with addresses but no postcode in OSM (with their
way IDs) and see if any match up with the Land Registry addresses. This way
we can add postcode to buildings rather than just to the roads.


 

Not sure if this is any easier/harder to do.

Regards,
Rob
