Geocoding

[David Lock]

Hello Folks

A quick question for you all as im sure some of you have looked into this before. We are looking at trying to get address data for the uk so that we can roughly locate sites and clients etc... I've been quoted £5500 for the Royal mail data with a 100m accuracy. Does anyone know of an alternative that's cheaper?

Cheers in advance

Do you actually need the data, or simply the ability to turn an address into a grid reference of lat/long pair? If the latter then there are any number of free services that might fit your needs, including several with APIs (nearby.co.uk might be worth a look).

As for buying the dataset, though, no idea I'm afraid!

All the best,

Jeremy

Couldn't possibly point you in the direction of wiki-leaks postcode data... http://bit.ly/efbnS

Altho the legalities of this have already been discussed....

And if postcodes is what you need, interesting tweet appeared the other day from Christopher Osborne (@osbornec) to http://www.cloudsourced.com/2009/10/20/cracking-the-postcode/

I used the Office of National Statistics Data a few years ago on a project and very good it is too, I just never realised they are so free and easy with their data!

 

There’s always OS AddressPoint also: http://www.ordnancesurvey.co.uk/oswebsite/products/addresspoint/ - I used this dataset in conjunction with the ONS data and it is really rather good.

 

And finally, OS CodePoint (with polygons) shows the postcode centroids/boundaries.

 

Both these OS solutions should be considerably cheaper than 5.5K but do still cost a bit, I recall. And both AddressPoint and CodePoint can also be used in ArcGIS for geocoding via the ArcGIS tools: Indeed, if I recall correctly, EsriUK host this and similar data online also so ArcGIS users can access it on a subscription basis.

Degree of granularity is an issue at present (see his blog and the comments). Although finest granularity of 146 housholds is useful for soooooo many applications

A point to note - there's a *lot* of debate over at the
data.hmg.gov.uk list about what exactly the license allows you to do
and in what context. It's not as clear cut as Chris suggests.

Cheers,
