Sitting around the data campfire

Similar to Gail Ramster, I went along to the Friday afternoon part of UK GovCamp 2012 without really knowing why. I suspect most people would say the same thing. You go because… well, you never know which useful people you might bump into, and what interesting things you might hear about. Plus a colleague Janet Hughes was going, and I’d cleared my desk of essential work for the week.

Here are a few takeaway thoughts from my afternoon.

1. I barely knew anyone

It’s years since I was a fish in a geeky pool, active in the free culture movement, the KDE community, software patent activism and other odds and sods.

For the past five years or so I’ve moved onto land, or perhaps a coral reef, to be more involved with issues around the environment, housing and pay inequality. The past two or so have been working as a local government employee at the GLA, supporting Green Party Members of the London Assembly. They have pushed for open data, but it’s not exactly a hot topic in our weekly meetings. My only remaining connection has been OpenStreetMap, my one geeky obsession.

Still, it didn’t matter, go along even if you know no-one at all.

2. It was nice to reconnect with optimistic techies

The event reminded me of one of the things I most like about these crowds: they’re all optimistic about the future and enthusiastic about the common interest.

I’m glad I managed to quickly chat to a few people I did know, sort of… Gail via Twitter, and Giles Gibson from the Herne Hill Forum, but sadly I only said as much as “hello” to people like Emer Coleman and Chris Osborne. That’s what you get for arriving late and leaving early.

3. It’s more meaty than you’d think

That’s “meatspace” as in “the real physical world”, compared to “cyberspace” online. Compared to events a few years ago on open data and technology, most of the discussion I heard was about councils and companies working on staff structures and consultation processes, and then thinking about how technology and data could help.

I used to get frustrated with discussions that started with the assumption that open data and technology was going to revolutionise the world. That seemed upside down to me. So I was pleasantly surprised at this.

4. There’s a lot of “we”

Somebody pointed this out in one session – it’s very easy to apply “we” to the wider population when you really mean “we sort of people in this room”.

Often “we” are innovators or early adopters of ideas that become more mainstream, like using a smart phone to access services. Sometimes “we” are set to be a significant minority, like journalists, bloggers and politicians who use data to enhance their investigatory work. Just as often “we” are a world unto our own.

It’s fine, innocent mostly, typical of any event with like-minded people. It just grated on me when people talked about reconfiguring public services or management around their preferences, as though the rest of the world will thank them.

I might make a badge for myself if I go again, with the slogan “we’re not normal” or similar!

5. Theres a lot going on out there

Cocooned in City Hall, working on affordable housing or the pay gap, it’s hard to keep even a toe dipped in this pool. It was great hearing from so many people in so many walks of work and life doing so many useful things.

Sometimes when I map an area for OpenStreetMap, walking down a street noting house numbers, I feel a bit bewildered by all these people living here! London feels impossibly enormous. I left UKGovCamp feeling similarly bewildered by the enormity of work going on in this field, relative that is to my own small bits and pieces in my job and my free time.

Problems and possibilities with ward boundaries

Being actively involved in my local branch of the Green Party means I’ve spent a lot of time wandering around carrying a map of a local ward.

Almost nobody seems to know which ward they are in, often because the names are a bit abstract (e.g. “The Lane” in Peckham, which I presume is because “Rye Lane” runs through the middle) or because almost nobody would say they live in the area described (e.g. “Peckham Rye”, which has Peckham Rye Common and Park in the middle and includes areas normally thought to be part of East Dulwich and Nunhead).

Since the Ordnance Survey published open data, including political boundaries, it’s been possible to put this information into OpenStreetMap. I’ve finally bothered to start doing this for Southwark – you can see the results on this nice ITO map.

Unfortunately the default map on the OpenStreetMap homepage draws the names of the wards along the rather nice dotted boundaries, displacing actual road names and leaving junctions that could easily confuse the user. Here are three examples:

You’ll notice I’ve added “ward” to the end of the names to try and help, but it’s not much of a solution. Three different proposals have been put forward on the OpenStreetMap bug tracker (a dedicated map, hide them, make them less bold).

A simple solution to the problem above would be to remove the names; a more sophisticated solution would be to give road names priority, change the text colour to the purple of the boundary lines, and hope Mapnik allows us to offset the labels so you can have the two ward names either side of the line).

It’s a bit of a shame that they create a mess because they’re useful data to include in OpenStreetMap (much like trees, which I’ve asked for a solution to).

For example, the holy grail of software to help us canvass voters would be to connect the electoral register to the OSM database of houses, allowing us to visualise and manage information on voting intentions and canvasser visits by ward on a nice map.

Another useful application could be Nominatim, which could tell you the political boundaries that any chosen OSM-mapped home, business, park or set of co-ordinates lies within.

For now I just need to finish getting all those Southwark boundaries into the database…

Data quality

One other quick point. The London Borough of Southwark boundary was already in the database, but it’s not very well mapped.

It’s really important to know if a boundary runs down the middle of the road, so that homes on one side belong to one borough and homes on the other side to another borough; or whether the boundary is offset away from the road, usually down back gardens, so that all homes on both sides are in the same borough.

Fellow OpenStreetMappers should be careful to put the boundary in exactly the right position, ideally sharing nodes/ways with the actual roads where the boundary goes down the middle so it’s precise and won’t go wrong if somebody adjusts the road position.

Never mind Wonga, use a credit union

Payday loans have been in the news today, with industry figureheads trying to persuade the public that they’re offering the punters a good service. Well, if you’re seriously stuck for cash you need or have loans you’re struggling to service, a much better place to start would be a credit union.

London Mutual Credit Union, for example, is a not for profit organisation that provides ethical financial services to Southwark and Lambeth boroughs. These services include savings accounts, current accounts and loans to people who find themselves financially excluded from high street banks. They have no shareholders, and all their profits are returned to members.

Unlike Wonga & co they are genuinely providing useful services without looking to make a very sizeable profit off the backs of the idiots and the vulnerable.

Anyone struggling financially would also be best off seeking help from the Citizen’s Advice Bureau and checking out the many handy tips on web sites like Money Saving Expert (a personal favourite).

Thankfully we won’t have Wonga sponsoring our public transport network this New Year’s eve. Apparently Boris has gone for a booze company instead, who promise to promote responsible drinking. Cheers!

Why map data sometimes matters

I was contacted recently by a parent campaigning for a local school to ensure its admissions policy is properly applied. Over-subscribed schools like this one are a common source of frustration and worry up and down the country.

Here’s the rub. Which of these two homes would you say is closer to the school, and therefore more likely to secure a place?  By the way, I’m not sure that the location on the left actually is within the catchment area, it’s just a place I randomly chose to illustrate the coming point…

Routes to the school from two locations using CloudMade maps, the home on the right wins by 500m.

Parents at the location on the right were told they were too far from the school. The method they use to calculate safe distances to the school actually suggests that the location on the right is farther away than the location on the left!

Why?

Because they are calculating distances using a model that measures the distance as if you are driving a car. If you try that, you get a totally different result:

Routes plotted for cars to get to the school, the home on the left wins by 400m.

The school’s model uses the Ordnance Survey ITN maps, and apparently doesn’t account for this short footpath at the end of one road. It was pedestrianised 25 years ago.

Happily OpenStreetMap has all the relevant data (and a few minor corrections the parent, Jasia, pointed out to me) so anybody can plot the route to prove the point.

Incidentally, if you fancy showing your support for this campaign download this letter to the governors, sign it and send it to the address at the top of the document.

Making open data maps the almost-easy way

One of the annoying things about open data is that you often need ninja skills to do anything with it. OpenStreetMap contains a wealth of geodata, but most tools make you jump through several steps involving the command line and all manner of data wrangling just to produce a custom map.

Maperitive tries to make it much easier to create nice looking maps. It has been in gestation since late 2007, and is now close to being easy to use.

It took me about half an hour of playing around to produce my first nice hiking map of Snowdon, although a problem with NASA’s elevation data led me on a frustrating journey to get Ordnance Survey open data in there to fill the gaps. I also had to work out Maperitive’s settings file for the way features are drawn to make the maps look a little neater and, well, British.

Making open data maps the almost-easy way

(Click on the images to see them on Flickr, where you can look at full sized versions).

Another hour messing around with the settings file and I had a nice map of an area my new father in law likes to go walking, the Long Mynd in the south of Shropshire. This time I aimed for something familiar to users of the Ordnance Survey walking maps.

Making open data maps the almost-easy way

The latest beta of Maperitive also allows you to export a 3 dimensional model using elevation data, and a flat image of the map. You can import these into a modelling tool, laying the map image over the 3d model, to produce nice graphics like this one of walking routes up Snowdon:

Making open data maps the almost-easy way

If the NASA elevation data works for you and you don’t want to change the style of the maps, it’s already a fantastic and fairly usable free-to-download tool. It’s a shame it isn’t free software with the code open sourced.

Southern Fried London hits the spot

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 an effort to do more with their garden than store old washing machines and weeds.

Like Jenny we ended up arousing the interest of the local media, which in turn led to a full page spread in the Daily Mail. We turned down subsequent invitations to debate garden design with TV personality gardeners on BBC Breakfast and Richard and Judy because they obviously missed the point and wanted us to attack the celebs or the garden owners.

It’s nice that Jenny clearly likes the chicken shop fronts, and isn’t just sneering.

My personal favourites aren’t all chicken takeaways, but you can find them on Denmark Hill. It starts with a Pizza Hut, which has been bested by a Tasty Hut just two doors over, followed a little further south by a Tasty House. Who will raise them a Tasty Mansion?

Theatre takes root in Peckham

It was probably the Peckham Pavilion at the Venice Biennale that cemented Peckham’s place in London’s art scene. Since then there has been a steady flow of journalists, hipsters and artists dropping in to study contemporary sculpture and relax in a trendy campari bar. But this art world has made little effort to reach out to, and integrate with, its host community.

So it was with some scepticism that I made my way to the brilliant Bussey Building for the launch of Theatre Local Peckham, the Royal Court’s second outing into a south London community to stage plays and theatre workshops. They’re hosted by Mickey Smith’s CLF art cafe, an unkempt converted factory normally home to drum and bass nights, community meetings and art fairs.

But I was wrong to be sceptical. The Royal Court’s artistic director spoke before the play of their Sloane Square theatre being exclusive, a place that many people might enjoy but would never visit because of its location. This emphasis on place ran through his talk: he wants the project to build a relationship in the community that will extend beyond the run of the two plays; the plays themselves being about how people live together.

Truth and reconciliation

The play we saw, by Debbie Tucker Green, was an unforgiving series of quiet – but sometimes explosive – confrontations.

A Rwandan woman repeatedly threw pleading questions at the man who killed her husband, challenging him to respond while he remained silent, shifting his body at first in unease, then in defiance, then unease. Three generations of a South African family waited for their enemy to appear, caught in a loop of concern about the hard chair while the mother stood apart, unable to sit until she got answers from the man who killed her eldest daughter twenty years ago. These and more stories wove around a dark, bare set of chairs and spotlights in the middle of the room.

This was not a play about the process of reconciliation so much as the pain and agitation that would form its backdrop.

I spoke after the play to Ivanno Jeremiah, who played the accused Rwandan man, about his background, the play, and what he thought it might mean to a Peckham audience:

Taking root in Peckham

I also managed to speak to Ruth Hawkins from the Royal Court, who had found my blog and invited me along to the launch. She put to rest any lingering doubt I had about this theatre landing in Peckham. Sorry about the sound quality, it was a noisy evening!

What I particularly like is the work with local schools. I spoke to a couple of local teachers – unfortunately the video is too noisy to be watchable. One, a drama teacher, told me her pigeon hole is “full to the brim with marketing from touring companies, theatre companies and site projects” trying to sell her tickets or workshops, so “it takes quite a lot to persuade us”. What sold this to her? The free writing workshops for kids being put in in their local area, connected to a play put on by a top notch theatre company.

Get down there yourself

The two plays are running until the 19th November, and you can pay what you like to see them. It would be great if this project was a real success, both for those putting the effort in and for the impact it might have on other arts groups looking to use Peckham’s cheap space.

Young people should be wary of the Government’s planning bonfire

I have noticed a lot of young people enthusiastically supporting the Government’s proposals to radically cut down planning regulations.

They join in attacks on groups like the National Trust and Friends of the Earth, calling them wealthy NIMBYs who are protecting their own over-inflated house prices. They buy into the suggestion that the planning system has held back house building, harming a growing proportion of the current generation of young people who are now “jilted”, priced out of home ownership.

Is this right?

I don’t think so. In fact, I believe the Government’s proposals are bad for young people, and bad for intergenerational justice.

Is planning the problem?

There can be no doubt that planning regulations are a drag on housing development, adding both the cost of the buildings themselves and the process of putting them up. But that’s like saying that the minimum wage and gender equality laws are a drag on business. They may be, but they’re regulations we value.

The evidence that the planning system is a bottleneck is weak. According to London Councils there are approximately 170,000 homes in London’s planning system with permission that aren’t currently being built – the constraint being scarce mortgage finance caused by the credit crunch and high land values.

In London Ken Livingstone used the planning system to force reluctant councils to build more houses, and increased output by almost 50% in a decade, though it was still about half the level required to stabilise prices through supply. Boris Johnson has continued with this approach, albeit with more of an emphasis on negotiation than force.

Would the private sector build more homes without the planning system? The only time in the past century that the UK has seen house building match demand, and kept housing affordable, was when councils built in huge volumes from the 1950s to 1970s.If you think price bubbles are all about supply, explain the continued volatility of house prices through the 1950s, 60s and 70s. The big home builders have little incentive to build large volumes and deflate the value of land, and never filled the gap when we stopped councils building in the 1980s. Have we given up hope of persuading the public to back large scale public house building?

Figures from the Department of Communities and Local Government.

The Government’s main reform is to radically simplify planning regulations. Are the regulations and guidance the problem, or are we overlooking the understaffed local planning authorities and unduly complex or slow processes?

Actually the biggest obstacle to building more housing is the cost of land. Unless we threw away any protections for the green belt and farm land that take up most of our country, or accept much higher density levels across the board, it will always be too scarce a resource for supply to match demand. There can be no doubt that we need policies that reduce the value of land, or at least contain the rises in land values (which are in fact the underlying reason for rises in the prices of existing houses).

Planning consent for housing transforms the value of farm land and brownfield land, so the argument goes that presumed consent would somehow help. I’m not convinced it would, and anyway we could call for proposals such as councils auctioning off land and using the planning gain to fund affordable housing.

Do we need to reduce planning costs as well as tackle land values, pushing for every tool in the box to be used? Is it simply that the current Government is serious about reducing planning costs, but that no minister since Lloyd George has shown a serious interest in reintroducing land value taxation?

Isn’t planning a solution?

My greater worry is that young people are forgetting the benefits of a detailed planning system.

If they are concerned with intergenerational equity, what greater disaster for the current youngest and future generations can there be than climate change? Successive governments may have failed to keep housing costs in check, but that failure pales into insignificance when we consider that decades of hot air on climate change policy have failed to even slow the global rise in greenhouse gase emissions.

The planning system is central to mitigating and adapting to climate change.

Without tough and highly prescriptive planning rules on car parking, road layouts, renewable energy and a long list of other policy areas, councils will continue to allow development that is incompatible with reducing emissions to a sustainable level. Labour failed to go far enough with the planning system, and just as excellent new rules on renewables were ready to be introduced, this Government has decided to scrap the lot and introduce some vague aspirations through which anti-green councils (being the majority in England) will drive a polluting coach and horses.

Can you see every council in England and Wales deciding that “sustainable development” requires a reduction in car traffic, fewer car parking spaces and proper provision of cycle routes?

Allowing people to convert offices into homes without planning permission could damage jobs and lead to the worst type of housing being built, without any regard to considerations of size or quality.

Protecting the green belt and farm land is important for climate change adaptation, not only in terms of protecting habitats (if only all farms were managed well) but more importantly for food security. It’s a long time since the UK was self-sufficient in food, but there are a number of pressures on food prices that will only get worse in the years to come: global population growth and an increase in per-capita demand for meat from grain-intensive cattle; oil prices that will only go in one direction long term, which not only fuels machinery but is also the basis for fertilisers and pesticides; and longer term the potential loss of many of the world’s bread baskets due to climate change taking hold.

We need to keep all the land we can for food production, so that future generations have a chance of keeping a high level of domestic food production using systems such as permaculture and aquaponics. This isn’t science fiction, the new London Plan even begins to discuss this concern.

The planning system can also help redress longstanding integenerational iniquities, such as requiring councils to plan for extra social housing (council and housing association housing) in wealthier areas, and ensuring that homes are always built with decent sized rooms (something this Government has reversed to simplify regulations).

These and other provisions could still be enshrined by more enlightened councils in the new slimmed down system, but they could be challenged if they stood in the way of building lots of houses and promoting economic growth. The benefits of will largely go to property developers and income rich people who can buy houses.

My suggestion to fellow jilted youth

By all means call for planning regulations to be streamlined where they are excessive, and to force NIMBY councils to permit more house building. Challenge conservation groups where they block the development of decent housing in areas that desperately need it, and where the justification is weak or self-serving.

But please don’t support this regressive Government in its efforts to tear up the planning system in the name of misdirected growth. The critics aren’t hysterical, hypocritical or self-serving; the concern is genuine and justified.

Getting speed limits into OpenStreetMap

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 sessions on my evening commute, using ITO’s excellent tool:

Orange roads are 30 mph, green are 20 mph or lower, grey are main roads without any data; all the minor roads without speed limit data just show through from the background. Getting more roads down to 20 mph will make them much calmer, more pleasant and safer for people on foot and bike.

Not a bad start, but we have a long way to go! I could probably get data out of TfL and Southwark Council. But I’m interested in seeing what I can actually find on the ground, both because the two sometimes don’t match up and because it made me aware of just how varied the signposting is.

With some roads it’s very obvious – it’s a short residential road with a signpost and a huge “20 mph” painted onto the road. On other roads you could easily miss it. Walworth Road has a 20 mph limit, but if you missed the single signpost going either north or south past endless distracting shops, signposts and shoppers, and buses that often block your view, you could be forgiven for assuming it’s 30 mph like most other roads.

Back to OpenStreetMap, it would be good to get better coverage of speed limits. I notice that some parts of the country like Norwich are very well mapped, while London – with the exception of my experiment, Islington and a little bit of Tower Hamlets – barely has any.

One for a winter mapping party, Harry? Or maybe another good reason to get cycling and pedestrian groups interested? I’ll talk to the Southwark campaigners…

Open scrutiny in the age of open data

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.
