Naughty, very naughty: Ernest Marples frees the postcodes
An interesting new site – ernestmarples.com/ – is trying to make postcodes free.
The people behind it (the whois details tell you that it’s registered to a location in SW1A 1AA, which happens to be Buckingham Palace) are Harry Metcalfe and Richard Pope.
They insist, when asked the question of “where does the data come from?” that
We’re not saying. But, just to be clear: we don’t hold a copy of the postcode database ourselves, neither in complete form nor as part of a cache.
But their aim is clear enough:
Post codes are really useful, but the powers that be keep them closed unless you have loads of money to pay for them. Which makes it hard to build useful websites (and that makes Ernest sad).
So we are setting them free and using them to run PlanningAlerts.com and Jobcentre Pro Plus. We’re doing the same as everyone’s being doing for years, but just being open about it.
Hopefully the Government and Royal Mail will realise the value of this service and license us to offer it officially and for free. If not, and this website gets shut down, we’ll close the websites we’ve made that make use of this site’s lookup service. Permanently.
There’s a long list of people who have supported it. We’ll add our voice. The Free Our Data campaign thinks it’s a good idea to make postcodes freely available.

If I go to Google Maps, enter a postcode, then paste the following line of Javascript into the address bar and Enter, I get the latitude and longitude of the centre of the map (I assume this is the ‘centre’ of the postcode.
javascript:void(prompt(”,gApplication.getMap().getCenter()));

I can’t see any substantive difference between what ernestmarples.com are doing and what Google offers: if the Royal Mail goes after ernestmarples.com then I assume that they would have to go after Google, and I know who my money would be on.
Perhaps someone could write a webservice that we can all offer using Google Maps if ernestmarples.com gets taken down.
