Full launch for Met crime maps

Wednesday saw the formal launch of London’s crime maps, which first appeared in beta only a couple of weeks back. Don’t call it ‘1.0’ though: the source code declares it’s actually ‘beta 1.02’.
As before, it shows areas colour-coded for the rates of ‘burglary, robbery and vehicle crime’, based on comparisons with ‘the average’. Yes, that’s an approach which has its limitations – my favourite being that areas containing police stations tend to rate worst for offences, because of (for example) finding drugs on someone you’ve just taken into the custody suite. But as a first step, it’s surely a good one. There are plenty of legal and logistical issues to overcome before we start putting dots on the map according to offences… and as we all know by now, if you try to sort everything out before going live, you never go live.
No mention of the total cost in the official press release, but I’ve seen a figure of £210,000 reported (eg Daily Mail). Given that it’s a fairly straightforward map mashup, using the standard infoWindows and polygons built into the (free) Google Maps interface, I’d be very interested to see a confirmation and/or breakdown of that. Fair play to Boris and his Conservative administration for getting it out the door early; but the next ‘how much did that government website cost?’ argument could be interesting.
Meanwhile, I see the Foreign Office is doing some map mashing of its own, with a cute (rather than useful) map of travel advice notices for the home nations’ World Cup qualifiers. But crucially, they’ve done it using the free ‘My Maps’ functionality; and it’s offered purely as an external link, not even an embed on the FCO page.

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.

Crime maps by Christmas

A Home Office press release this morning makes the explicit pledge: ‘Every neighbourhood in England and Wales will have access to the latest local crime information through new interactive crime maps. […] By the end of the year every police force area will produce crime maps which will allow the public to see where and when crime has happened, down to street level for some crimes; make comparisons with other areas; and learn how crime is being tackled by their local neighbourhood policing team.’
On the face of it, that’s brilliant news. But five months to do this? That’s brave – especially when we’re looking at some pretty fundamental legislative questions, as highlighted on the Power of Information blog last week. The Guardian’s Free Our Data campaign blog has a few recent items along similar lines.

Power Taskforce's ideas on crime maps

The Home Office is confirming that it’ll press ahead with online crime mapping, as recommended by today’s Casey Report on Engaging Communities in Fighting Crime.
Even better, the Power Of Information taskforce – specifically Will Perrin and Tom Loosemore, in apparent association with designers Schulze and Webb – have posted a few concepts showing not only the mapping of crime data, aggregated to postcode sector; not only an overlaid layer of data showing public facilities such as schools, pubs and cash machines; but also the ability to actually do something as a follow-on. I’m especially intrigued by the RSS icon: blogging bobbies, perhaps?

Judging by the mockups anyway, we’re looking at some serious interaction potential: polling on local priorities, emailing the local policing team or your local elected representatives. (Never mind the possibility of interacting with the data.)
It’s not the first time some/most of this has been proposed: whilst working at National Statistics, I was involved in the concept work which ultimately led to the disappointing Neighbourhood Statistics. It’s not as if we didn’t have some of these same ideas… but mashing-up has come a long way since then, thanks particularly to Google Maps. I note the ‘presumption’ that Google’s technology would underpin these maps… another nail in Ordnance Survey’s coffin?
