Met launches London crime maps

London’s Metropolitan Police has launched the first test of its planned ‘crime mapping’ application, and at first glance, it’s really quite nice. There’s data from borough to ‘sub-ward’ (a few streets), although at the moment it’s only carrying aggregated totals of ‘burglary, robbery and vehicle crime’.
The ‘high/average/low’ colour coding makes it easy to take in; and navigation is pretty good. The selection of statistical geography is inferred from the zoom level of the map – a method which has its ups and downs. But with a postcode search, it’s easy to go directly to ‘your patch’. (I’m a bit dubious about the accuracy of the boundaries, though.) Throw in some nice little Javascript-y UI touches, and you’ve got an excellent start – with the promise of ‘further enhancements … prior to the formal launch of the service in September.’
But what’s most striking about this? It’s done on Google Maps. Here’s a extra-high-profile government mapping application, and they’ve made a conscious – and entirely predictable – decision not to build it using the tool provided by the government’s own mapping agency.
It’s not a million miles away from the vision put forward by the Power of Information taskforce; Tom Loosemore calls it ‘a decent first effort’, but laments the ‘lack of proper profile for your local coppers’.

An idea whose time has come

Crime mapping is front-page news today (in the Telegraph anyway). Most of the stories follow a predictable pattern: Ministers say it will inform the public, and make the police more accountable, but it’ll lead to house price chaos. Etcetera.
But I’m finding myself infuriated by the Telegraph leader column which proclaims:

The Conservative Party has appeared a little paranoid over the past year or two with its reluctance to set out detailed policies for fear of them being plagiarised by Labour. […] The latest was yesterday’s commitment from Jacqui Smith, the Home Secretary, to publish crime maps for England and Wales by the end of this year. This is based on the Conservative Party policy document Giving the Public a Crime Map (PDF), which was published in April and which formed a key plank of Boris Johnson’s successful campaign for the mayoralty of London.

So.. did Boris Johnson cook up the idea, all by himself? Hardly.
The project which first brought the idea to prominence was pioneering geek-journalist Adrian Holovaty’s ChicagoCrime.org, launched back in May 2005. It received global media coverage, on the web and in print; and was specifically mentioned as a case study in this government’s Power Of Information review, published in April 2007. (The project has since evolved into Everyblock.)
Further, two UK pilot studies are being quoted in news coverage today. DNS records show that MyNeighbourhood.Info, run by West Midlands Police, was conceived as far back as 10 May 2006; the site itself was launched in September 2007. The West Yorkshire site, beatcrime.info, traces back as far as April 2004, with a launch in February 2005. (Incidentally… do those dates provide a clue as to the lead time needed to produce these sites?)
So by all means, we can have pointless arguments about which UK political party first stole the idea from Adrian Holovaty if you like. It won’t get us anywhere. The point is, this is an idea whose time has come.
The luxury of opposition is that you can throw ideas around, without having to actually implementing them. The burden of government is that you have to overcome the technical, legal and procedural hurdles to get the things out the door. And we’ve got ample evidence that this is happening already.
