Here’s to Jenny Newham’s Southern Fried London, a collection of our finest grease merchants and heart attack hucksters. Thanks also to the weird and wonderful world of the South London Press, one of two locals in my neck of the woods, for bringing the blog to my attention. I embarked on my own obsessive photo-documentary project with a friend in an otherwise ordinary market town many years ago, snapping photos of ugly gardens in Bedford. For a year or so I couldn’t walk along a street without noting ugly gardens and trying to remember their location. Perhaps a precursor to my mapping hobby? The project was intended as a loving tribute to the dull places in which most of us live, and a comment on the influence of the endless gardening TV programmes at the time rather than a criticism of the owners. I doff my hat to anyone who makes…

I’ve started trying to add speed limits data to roads in my patch of Southwark. Two things made me start looking at them… First, I go everywhere by bicycle, which means speed limits and London congestion are of very little relevance to my journey times. But I noticed that journey planners like CloudMade’s offer wildly optimistic journey times for cars. Even ignoring congestion, I thought, they can’t be taking account of speed limits, which across London are lower than the national assumptions. For example, most main roads have a 30 mph speed limit and a growing number of roads, residential and main, have a safer 20 mph limit. The second reason is that speed limits have been a big issue for cyclists recently, featuring in campaigns around issues like Blackfriars Bridge and Southwark’s Transport Strategy. So here’s a snapshot of our data around Peckham and East Dulwich after a few…
This is the first of perhaps two or three short essays inspired by Emer Coleman‘s masters dissertation on open data, written in a personal capacity and not as part of my job. In this post I want to look at what her proposed model of “iterative and adaptive open government” would mean for scrutiny of the Mayor of London. Her dissertation considers the difference between the New Public Management approach, characterised by public managers setting the goals and other public managers auditing their performance, and an emerging “Open Governance” approach using open data.
Andy Allan’s excellent post on cycle campaigning reminded me to blog about some mapping help I’ve given a campaign group called the Elephant Amenity Network. One of their long-running issues has been the clearance and demolition of the unfairly maligned Heygate Estate, over 1000 council homes that should have been refurbished for council tenants instead of being knocked down for aspiring home owners to move into the area. One of the best features of the Heygate Estate is the urban forest that has grown there in the past thirty or forty years. But the few remaining residents and local campaigners fear the “regeneration” will see many or even most of them cut down. Through a friend who is involved with the campaign, I came along to help them map the trees that are there now. Knowing what you have seems like a good first step to saving it. So I…
It’s selection time for the Green Party. In London we are voting not only on our list for the House of Lords (in case we get offered another seat there), but also for the London Assembly and Mayor. Since I work at the Assembly and I’ll be writing the manifesto for whichever people are chosen, I don’t want to endorse anyone here. But I do want to share a a few thoughts on what I’m looking for in a politician. The most important thing for Greens to consider is that we will most likely only get one, two or three London Assembly members out of 25. There’s no room for colourful characters with narrow interests, bad tempers or a tendency for self indulgence. They need to be good communicators, both practical and radical, collegiate and disciplined. We need to pick people who can get complicated and often innovative messages across to…
As another flurry of snow hits the office windows here at City Hall, we’ve put the finishing touches to a video by Darren Johnson investigating the future of insulation in London (and the reasons why over a million homes are still bleedin’ cold!)
Two parallel worlds are starting to rub up against each other – open data enthusiasts and local activist groups. As Sam Smith has pointed out, embedding the power of open data in other worlds such as local activism has barely begun. Maps are one medium where I’ve been trying to bring these worlds together. Stepping into the ring In the left corner we have people like Rob Hopkins, who has just written a great summary of Transition Town groups mapping wild food, local groups and visions of the future. This wonderful work makes use of relatively open tools like Google Maps, but (so far as I can see) they make absolutely no use of open data, and keep all of their data in their own separate mapping systems. In the right corner we have open data crowds like OpenStreetMap, and after some prodding from me the Greater London Authority and…
Coverage of “points of interest” in OpenStreetMap is a point of pride for many mappers. Our maps have much richer detail than commercial competitors, they provide endless handy data for mashups, and as a consequence have been a big focus of mapping party efforts in London. But should we really be so keen? I’m not so comfortable for two reasons. First, how up-to-date is our data? I’ve recently re-surveyed my local area in minute detail and found several takeaways, shops and banks that have closed down or changed hands. I’ve also discovered that we have very poor coverage of cycle parking in Southwark following two years of massive expansion by the council. How likely is it that these are being regularly checked and updated? I suspect “not very likely at all”, and have therefore decided to delete all my points of interest in my local area that I’m not confident…
My latest experimentation in environmental maps has been launched on the Peckham Power web site. It grabs the set of energy generators in London (updated every hour from OpenStreetMap) and plots low/zero carbon generators on the map with icons and information to tell you what sort of technology each one uses. The idea is to, eventually, impress people who didn’t realise just how much of this exists in London already. In developing the code that creates the clickable points, I realised that the OpenStreetMap tagging schema doesn’t cope with the many different types of technologies very well. So I am currently taking a detailed proposal through the wiki process to rationalise and expand the “power=generator” feature – comments welcome! It will go to a vote in a couple of weeks. As Oliver Kühn has pointed out, data contributors aren’t always aware of the needs of data consumers. The very sparse…
Being a Green, I’m not following Labour’s hustings for their Mayor of London candidate too closely. But being a realistic left-of-centre Green, I’m hoping that either Ken or Oona get elected into City Hall in 2012. Oona King hasn’t impressed me much so far. Her candidacy seems very light on detail, her policy pronouncements full of nice language but no specifics. As Martin Hoscik writes, Ken Livingstone is simply rehearsing his 2008 manifesto, with a few innovations (such as borrowing affordable housing money on the bond market) that are basically unfolding behind the scenes in City Hall already. But on the BBC Politics Show on Sunday, King did get one impressive point in. Livingstone is basically gearing up for a re-run of the 1980s, when he battled with Thatcher from the GLC. He wants to fight, fight, fight every cut (transcript here). But as King pointed out, once the Mayor…
