Our most recent improvement to FixMyStreet means that users in Bromley will experience some clever routing on their reports.
It’s something quite a few FixMyStreet users have requested, telling us that they’d reported a street issue in London, only to have a response from their authority to say that it was located on a ‘red route‘ — roads which are the responsibility of TfL rather than the council.
Of course, most councils have systems set up so that they can easily forward these misdirected reports to the right place, but all the same, it wasn’t ideal, and added another step into a reporting process we’ve always tried to keep as simple and quick as possible.
Thanks to some development for Bromley council, we’re now glad to say that within that borough, reports on red routes will automatically be forwarded to TfL, while other reports will be sent, as usual, to the relevant council department.
As a user, you don’t have to do a thing (although you can see this automated wizardry in action by watching changes in the text telling you where the report will be sent, as you click on the map in different places and select a different category – give it a go!).
Note that this functionality has not yet been extended to the FixMyStreet app; however in the meantime it will work if you visit fixmystreet.com via your mobile browser.
A new layer
As you’ll know if you’re a frequent FixMyStreet user, the site has always directed reports to the right UK council, based on the boundaries within which the pin is placed.
And equally, even within the same area it can discern that different categories of report (say, streetlights as opposed to parking) should be sent to whichever authority is responsible for them: that’s an essential in a country like the UK with its system of two-tier councils.
So this new innovation just meant adding in a map layer which gives the boundaries of the relevant roads that are designated red routes, then putting in extra code that saw anything within the roads’ boundaries as a new area, and TfL as the authority associated with road maintenance categories within that area.
FixMyStreet has always been flexible in this regard: you can swap map layers in or out as needed, leading to all sorts of possibilities. Yesterday, we showed how this approach has also averted one common time-waster for councils, and the same set-up is behind the display of council assets such as trees and streetlights that you’ll see for some areas on FixMyStreet.
The integration of red routes is available for any London Borough, so if you’re from a council that would like to add it in, get in touch. And to see all the new innovations we’re working on to make FixMyStreet Pro the most useful street reporting system it can be, check out the website.

If you visit FixMyStreet and suddenly start seeing spots, don’t rush to your optician: it’s just another feature to help you, and the council, when you make a report.
In our last two blog posts we announced Buckinghamshire and Bath & NE Somerset councils’ adoption of FixMyStreet Pro, and looked at how this integrated with existing council software. It’s the latter which has brought on this sudden rash.
At the moment, you’ll only see such dots in areas where the council has adopted FixMyStreet Pro, and gone for the ‘asset locations’ option: take a look at the Bath & NE Somerset installation to see them in action.
What is an asset?
mySociety developer Struan explains all.
Councils refer to ‘assets’; in layman’s language these are things like roads, streetlights, grit bins, dog poo bins and trees. These assets are normally stored in an asset management system that tracks problems, and once hooked up, FixMyStreet Pro can deposit users’ reports directly into that system.
Most asset management systems will have an entry for each asset and probably some location data for them too. This means that we can plot them on a map, and we can also include details about the asset.
When you make a report, for example a broken streetlight, you’ll be able to quickly and easily specify that precise light on the map, making things a faster for you. And there’s no need for the average citizen to ever know this, but we can then include the council’s internal ID for the streetlight in the report, which then also speeds things up for the council.
So, how do we get these assets on to the map? Here’s the technical part:
The council will either have a map server with a set of asset layers on it that we can use, or they’ll provide us with files containing details of the assets and we’ll host them on our own map server.
The map server then lets you ask for all the streetlights in an area and sends back some XML with a location for each streetlight and any associated data, such as the lamppost number. Each collection of objects is called a layer, mostly because that’s how mapping software uses them. It has a layer for the map and then adds any other features on top of this in layers.
Will these dots clutter up the map for users who are trying to make a report about something else?
Not at all.
With a bit of configuration in FixMyStreet, we associate report categories with asset layers so we only show the assets on the map when the relevant category is selected.
We can also snap problem reports to any nearby asset which is handy for things like street lights as it doesn’t make sense to send a report about a broken street light with no associated light.
Watch this space
And what’s coming up?
We’re working to add data from roadworks.org, so that when a user clicks on a road we’ll be able to tell them if roadworks are happening in the near future, which might have a bearing on whether they want to report the problem — for example there’s no point in reporting a pothole if the whole road is due to be resurfaced the next week.
Then we’ll also be looking at roads overseen by TfL. The issue with these is that while they are always within a council area, the council doesn’t have the responsibility of maintaining them, so we want to change where the report is going rather than just adding in more data. There’s also the added complication of things like “what if the issue is being reported on a council-maintained bridge that goes over a TFL road”.
There’s always something to keep the FixMyStreet developers busy… we’ll make sure we keep you updated as these new innovations are added.

What’s the best way to get your supporters to campaign, when the finer details of what they’re pressing for may vary from place to place? That’s the issue that faced Prostate Cancer UK as they call for better provision for men across the country with erectile dysfunction as a result of prostate cancer.
There are five core treatments for tackling erectile dysfunction, but whether all of them will be offered to you depends on your postcode. In some areas, all are offered as standard, while in others there may be none.
The tool we built for Prostate Cancer UK used several of mySociety’s areas of expertise, from mapping to user testing — we even used Freedom of Information. And putting it all together, we have a powerful campaigning platform that responds to users’ location, while raising awareness and pushing for improvement.
Prostate Cancer UK’s Erectile Dysfunction campaign site informs people about what care should be available to those who experience the condition as a result of prostate cancer treatment, and urges them to write to their local health commissioner if provision is poor in their area.
Educating, campaigning, sharing
The user is first informed: they are shown the five factors which constitute good treatment of erectile dysfunction. After that, they are prompted to input their postcode to see how many of those measures are provided by the NHS body responsible for their region.
If provision is poor, they are encouraged to help campaign: users can opt to write to their Clinical Commissioning Group (CCG), Health Board or Health and Social Care Board to ask them to improve what’s available. They are given the choice between writing a letter from scratch, or using a pre-composed template which also contains a section for the writer to add a paragraph of their own words — a pragmatic balance that avoids an influx of identical form letters, while still addressing fact that when users are faced with a completely blank page, many will drop out of the process.
When you’ve done that, for those in England there’s also an opportunity to contact Jeremy Hunt, Secretary of State for Health to highlight the variation in treatment for erectile dysfunction and establish which organisation is responsible for the national commissioning guidelines.
Finally, the user is invited to share what they’ve learned, via Facebook, Twitter or email. Our user testing revealed that, contrary to our worries, people were happy to do this without embarrassment.
How it works
Like most of mySociety’s own sites, the ‘Better Care’ site uses MapIt to match the user’s postcode with a boundary, in this case the boundaries of the CCGs, Health Boards and Health & Social Care Boards. That’s how we deliver the information about what’s available in their local area.
When you input your postcode to see how your local provisioners are doing, MapIt also delivers information for other areas, including a couple of close neighbouring ones. This allows us to provide a nice comparison, along with the statistic that shows whether your provisioner is better, worse, or within the same range as the average.
But how did we gather the data to tell you how well each CCG, Health Board or Health and Social Care Board is catering for erectile dysfunction patients? Well, fortunately, thanks to our own WhatDoTheyKnow website, it was relatively easy to send a Freedom of Information request to every one in the country — 235 of them in total. The WhatDoTheyKnow volunteer admin team were able to help with this large batch request.
Once we had all the data and a general idea of how the tool would work, we took an early version out to test it with users. The insights we gained from this process were, as always, extremely useful, and led to us altering page layouts and other elements that made the whole process as clear as it could be.
Finally, we incorporated quite a bit of statistics-gathering into the whole tool, so that Prostate Cancer UK would be able to see where their campaign might benefit from further optimising in the future.
All in all, we’re very glad to have been part of this important campaign to help men understand what’s available to them, and where they might need to push for more.
This post describes work for a museum exhibit which has now come to an end.
If you would like to commission similar technologies, please get in touch.
In the middle of the 9th Century, the territories of mainland Britain were in constant flux, with power shifting between the established Anglo-Saxon kingdoms and Viking settlers.
Towards the end of the century, the battles and power shifts reached a kind of equilibrium, with Alfred King of Wessex and Guthrum the Danish warlord agreeing a treaty defining the boundaries of their kingdoms.
One of these boundaries was demarcated by Watling Street, an ancient trackway that stretched from Shrewsbury in the west of England to the Thames estuary in the east.
The boundaries of Britain are different today, but the vestiges of this ancient divide remain in the names of the places that surround us.
To illustrate this, mySociety has been working with the British Museum, with data sourced from the University of Nottingham’s Institute for Name-Studies. We’ve created a simple interactive map as part of their Vikings Live event to show the Norse influence on around 2,000 place names in different parts of the United Kingdom and Ireland.
For each place, we’re showing its etymology, a breakdown of the different elements that make up its name and a link to the nearest cinema that will be showing the British Museum’s Vikings Live—a private view of the BP exhibition Vikings: life and legend in the company of world experts, presented live in your local cinema.
So, for a completely different perspective of the place names near your home, head over to the British Museum’s site to explore the influence the Vikings had on the names where you live. And, next time you’re in a Thorpe, a Howe, a Kirkby, or even in Grunty Fen (our favourite place name), think of the Vikings who’ve left an indelible mark on the toponymy of the United Kingdom and Ireland.
A commission from the Welsh Government has resulted in new functionality for Mapumental, which now has the capability to display multiple points and to produce RAW data compatible with GIS applications. Here’s how it happened.
How accessible is your nearest school, post office, or GP’s surgery? In Wales, that’s not always a simple question: the country’s mountainous landscapes, rural populations, and sometimes infrequent bus services can mean that those without cars are rather cut off from public service provision.
But of course, like any other authority, the Welsh Government has an obligation to quantify just how accessible their services are.
For many years, they have done so using a number of different methods. Some of these involve literally millions of point to point calculations – so, naturally, when Bill Oates, Head of Geography & Technology, Knowledge Services at the Welsh Government, approached Mapumental, he was keen to discover whether we could simplify things.
We were keen to try it, too – plotting multiple points would add a whole new slew of possibilities to Mapumental. Previously, Mapumental has been all about travel from a single point, and this functionality would bring new applications across all kinds of industries and users.
There’s only one way to find out
The sensible way forward was to pick a single service and see what we could do. One of the government’s open data sets showed positioning of all the secondary schools in the country, and would give us a very good indication of how manageable the task would be across all other provisions.
So we set ourselves this aim: to display the shortest transit time to get to any secondary school in Wales, from any point in that country.
This project was not like the map we made for the Fire Protection Association last year, with its postcode input and interactive sliders. It bore more relation to our static maps, but with the additional dimension that the single map would have multiple points plotted on it. Each point would display its own associated journey times, and where travel to one school was quicker than to another, it would have to override the data of the school that was further away.
And here’s the (very pretty) result
Transit times by public transport to secondary schools in Wales, with an arrival time of 9:00am.
Time bands are in 15-minute increments, with red areas being those where schools are accessible within a 15-minute journey (the centres of the red dots therefore also represent the positions of the schools).
Purple areas are those where journey time is between 1.75 and 2 hours, and the colours in between run in the order you see bottom right of the map. White areas (much of which are mountainous and sparsely-populated) are outside the two-hour transit time.
But there’s more – data for GIS
Plotting all the schools on a single map required quite a bit of modification to Mapumental, but there was another important part of the project that also had to be worked on, if the output was to meet all the needs of the Welsh Government.
They needed to be able to export the raw transit time data to their own GIS tools – the tools that they use to feed into official statistics. This allows the transit time data to be combined with other datasets, such as population density, for in-depth analysis.
We added a feature which allows Mapumental to produce what is known as a ‘raster grid’ output – basically, an enormous matrix that gives every pixel on the map a travel time value. To do this, we used the open source GRASS format.
Bill Oates is keen to see where this project can go:
“I’m really excited at the prospect of combining the power of Mapumental with our open data, and fully understanding how accessible Welsh public services are by public transport.”
To him, the benefits are clear:
“Mapumental’s approach is significantly quicker than our current methods, so this work will help save us time as well as providing a more engaging output.
“We hope that future work with mySociety will give us a sustainable approach to calculating the accessibility of local shops, hospitals, post offices and other services on an ongoing basis to help ensure that we’re meeting the needs of our citizens.”
We’re looking to build on our success, and offer this service to others – initially on request but via our API as soon as we can. We’ll keep you posted as to our progress.
You can see multiple-point mapping in action, on our Mapumental Property project – now the tool allows house-hunters to take more than one person’s commute into consideration when choosing where to live.
Who might use Mapumental?
Now that Mapumental can plot transit times from multiple points, and provide RAW data for GIS applications, we have great potential for use by anyone interested in travel and accessibility. That could be in central and local government strategy, town planning, architectural consultancy, transport provision, large enterprises looking to save on parking, or start-ups in the green transport space…to name but a few.

If you’re searching for a new home, give Mapumental Property a try. lt narrows property results down, only showing you houses that fall within a decent commute time from the places you visit regularly – like work, school, or the shops. Here, have a go – it’s fun.
Irritation is the mother of invention
Several years ago, some of our colleagues were looking for a house to rent.
They weren’t set on a particular town. There were two important factors: that it was within a reasonable commute from central London, where they frequently attended meetings; and that the rent was affordable.
Faced with these requirements, most of us would sift through property sites and cross-reference the listings manually with public transport information. It’s rather time-consuming, and slightly irritating, but hey-ho, it has to be done.
But mySociety is in the business of building useful web tools, so when something irritates us like this, we look to see if we can solve the problem through the magic of code. In a stroke of good timing, it was at just around this time that the Department for Transport approached us to ask us to work with their public transport data – and Mapumental was conceived.
The key was to combine Ordnance Survey postcodes with the DfT’s data about journey times, NPTDR (National Public Transport Data Repository). This data set takes a ‘snapshot’ of every public transport journey in Great Britain for a selected week in October each year.
Sounds simple? The process was not without its challenges. Prime among them was the problem of displaying map tiles, plus the vast quantities of transport data, within a reasonable amount of time, no matter which postcode or zoom level the user chose. As we know, a ‘reasonable amount of time’ for a page to load is a metric which is forever shrinking.
By 2006, we had created Mapumental’s first iteration. Users could input a postcode and see all areas of the country that could be reached by public transport, divided into coloured travel-time bands. In 2009, Francis Irving, the mySociety coder behind Mapumental’s early endeavours, explained the technology he’d used. It was Flash-dependent, and a few years later, developer Duncan wrote about some of the technical hurdles he overcame replacing the Flash elements, in view of the rise of the iPhone, which famously doesn’t ‘do’ Flash.
Hoorah! Now our colleagues could type in a central London postcode and see everywhere that fell within a 40-minute journey from there. It wasn’t long before we added median house price data, too.
Beauty is in the eye of the crowd
We even added a ‘scenicness’ rating: if the beauty of your surroundings was important to you, you could rule out anywhere below a certain level of attractiveness.
How did we assess how scenic every area in the UK is? By crowdsourcing the information – our ScenicOrNot website displays a random photograph from every square mile of the British isles, inviting people to rate them. It is surprisingly compulsive.
A showcase tool
Mapumental may have been born from our own needs, but we knew from the beginning that it would have wider applications. It has always been the sort of project that got people excited, once they saw it in action.
We wanted to show how elegantly Mapumental can handle all kinds of data, starting with houses for sale and rent – so we developed Mapumental Property. It’s not intended as a serious competitor to the giant property websites out there. Rather, it’s an all-singing, all-dancing demonstration of Mapumental’s strengths.
In this case, the data is from the property website Zoopla, and you can narrow it down to show rental or sales property within your chosen price bands and commute distances. You can even add multiple destination points, so that households of two or more people can find their optimum location.
But Mapumental is not just about property: swap out that Zoopla layer, and you could put in anything else you can imagine – hospital locations, supermarkets, schools, job vacancies… you name it.
The beauty of Mapumental is that now we’ve done the really hard part, incorporating new data layers is relatively simple. Recent work for the Fire Protection Association and the Welsh Government, among others, has shown its versatility.
Now how about you?
We believe that Mapumental’s possibilities are pretty much endless. Have you got an unloved, difficult-to-navigate dataset that Mapumental could breathe new life into? Or would your stakeholders benefit from being able to see your data displayed on a map? Let us know.
All of us at mySociety love the fact that there are so many interesting new civic and democratic websites and apps springing up across the whole world. And we’re really keen to do what we can to help lower the barriers for people trying to build successful sites, to help citizens everywhere.
Today mySociety is unveiling MapIt Global, a new Component designed to eliminate one common, time-consuming task that civic software hackers everwhere have to struggle with: the task of identifying which political or administrative areas cover which parts of the planet.
As a general user this sort of thing might seem a bit obscure, but you’ve probably indirectly used such a service many times. So, for example, if you use our WriteToThem.com to write to a politician, you type in your postcode and the site will tell you who your politicians are. But this website can only do this because it knows that your postcode is located inside a particular council, or constituency or region.
Today, with the launch of MapIt Global , we are opening up a boundaries lookup service that works across the whole world. So now you can lookup a random point in Russia or Haiti or South Africa and find out about the administrative boundaries that surround it. And you can browse and inspect the shapes of administrative areas large and small, and perform sophisticated lookups like “Which areas does this one border with?”. And all this data is available both through an easy to use API, and a nice user interface.
We hope that MapIt Global will be used by coders and citizens worldwide to help them in ways we can’t even imagine yet. Our own immediate use case is to use it to make installations of the FixMyStreet Platform much easier.
We’re able to offer this service only because of the fantastic data made available by the amazing OpenStreetMap volunteer community, who are constantly labouring to make an ever-improving map of the whole world. You guys are amazing, and I hope that you find MapIt Global to be useful to your own projects.
The developers who made it possible were Mark Longair, Matthew Somerville and designer Jedidiah Broadbent. And, of course, we’re also only able to do this because the Omidyar Network is supporting our efforts to help people around the world.
From Britain to the World
For the last few years we’ve been running a British version of the MapIt service to allow people running other websites and apps to work out what council or constituency covers a particular point – it’s been very well used. We’ve given this a lick of paint and it is being relaunched today, too.
MapIt Global is also the first of The Components, a series of interoperable data stores that mySociety will be building with friends across the globe. Ultimately our goal is to radically reduce the effort required to launch democracy, transparency and government-facing sites and apps everywhere.
If you’d like to install and run the open source software that powers MapIt on your own servers, that’s cool too – you can find it on Github.
About the Data
The data that we are using is from the OpenStreetMap project, and has been collected by thousands of different people. It is licensed for free use under their open license. Coverage varies substantially, but for a great many countries the coverage is fantastic.
The brilliant thing about using OpenStreetMap data is that if you find that the boundary you need isn’t included, you can upload or draw it direct into Open Street Map, and it will subsequently be pulled into MapIt Global. We are planning to update our database about four times a year, but if you need boundaries adding faster, please talk to us.
If you’re interested in the technical aspects of how we built MapIt Global, see this blog post from Mark Longair.
Commercial Licenses and Local Copies
MapIt Global and UK are both based on open source software, which is available for free download. However, we charge a license fee for commercial usage of the API, and can also set up custom installs on virtual servers that you can own. Please drop us a line for any questions relating to commercial use.
It’s high time we updated you on Mapumental, our journey-time mapping project. For those who may not remember, Mapumental is based on a simple idea: to visualise transit times, by public transport, from or to any postcode in Great Britain.
It all began in 2006, when the Department for Transport approached us to see what we might do with public transport data; in 2009 we won an investment loan from Channel 4 and Screen West Midlands which enabled us to build a beta tool – you might have played with it. If not, go on, have a go. It’s fun!
It’s been quite a long journey to where we are today. Unlike many mySociety projects, funding for Mapumental’s development came from a commercial investment loan, with a condition that we set it up as a business. For that reason, it’s not enough that it’s beautiful and useful – we need to find ways for it to be profitable, too. All revenues are set to come back to fund our not-for-profit activities.
We could tell from very early on in the project that Mapumental would be a sought-after tool for all sorts of purposes, from business to personal use. For example, you can see commute times at a glance, so it’s great for house-hunters and job-seekers. Consequently, it’s also great for the property and recruitment industries.
“Your maps look amazing, such a great way of representing what could be really boring data, but isn’t.” – A jobseeker
We can see loads of other possibilities too – like urban planning. This sort of analysis would have been far more expensive in the past; with Mapumental, planners can see at a glance how accessible a new development would be by public transport. Its potential uses are wide-ranging, answering questions for businesses, organisations, charities, and public facilities – especially those wanting to maximise accessibility or encourage use of greener transport options.
“The maps are a fantastic, a great tool and should be used for every planning application. I will be using Mapumental for all of our projects!” – Lee Taylor, Veridis Design
We’ve recently refined a product that’s pared down from the dynamic maps you may remember from that beta tool: static maps. These are simple, non-interactive maps which show transit time in bands. They’re flexible in that they can be generated for any postcode, with any maximum travel time, and depict travel at any given time of day.
We can provide a one-off map for personal use, or batches of many thousands of maps – as we have done for estate agents Foxtons, who now have a Mapumental map on every property listing.
As we generate more and more maps for different uses, showing different parts of the country, we’re really enjoying digging out all sorts of surprising facts – like how it’s quicker to travel from Watford to Westminster than it is from some parts of Harringay. Or how Cardiff University students might sensibly live at all points east as far as Newport, but will be stymied for transport in the west if they live anywhere other than Barry or Bridgend.
In fact, our very favourite use so far has come from an individual who centred his map around his home postcode. He tells us he has printed it off and put it up by the front door, so that on his way out of the house, he can find a new and surprising destination for day-trips.
Find out more on the Mapumental website – and please do spread the word among friends and colleagues who might benefit from a Mapumental map.
We’ve added a variety of new features to our postcode and point administrative area database, MaPit, in the past month – new data (Super Output Areas and Crown dependency postcodes), new functionality (more geographic functions, council shortcuts, and JSONP callback), and most interestingly for most people, a way of browsing all the data on the site.
- Firstly, we have some new geographic functions to join touches – overlaps, covered, covers, and coverlaps. These do as you would expect, enabling you to see the areas that overlap, cover, or are covered by a particular area, optionally restricted to particular types of area. ‘coverlaps’ returns the areas either overlapped or covered by a chosen area – this might be useful for questions such as “Tell me all the Parliamentary constituencies fully or partly within the boundary of Manchester City Council” (three of those are entirely covered by the council, and two overlap another council, Salford or Trafford).
- As you can see from that link, nearly everything on MaPit now has an HTML representation – just stick “.html” on the end of a JSON URI to see it. This makes it very easy to explore the data contained within MaPit, linking areas together and letting you view any area on Google Maps (e.g. Rutland Council on a map). It also means every postcode has a page.
- From a discussion on our mailing list started by Paul Waring, we discovered that the NSPD – already used by us for Northern Ireland postcodes – also contains Crown dependency postcodes (the Channel Islands and the Isle of Man) – no location information is included, but it does mean that given something that looks like a Crown dependency postcode, we can now at least tell you if it’s a valid postcode or not for those areas.
- Next, we now have all Lower and Middle Super Output Areas in the system; thanks go to our volunteer Anna for getting the CD and writing the import script. These are provided by ONS for small area statistics after the 2001 census, and it’s great that you can now trivially look up the SOA for a postcode, or see what SOAs are within a particular ward. Two areas are in MaPit for each LSOA and MSOA – one has a less accurate boundary than the other for quicker plotting, and we thought we might as well just load it all in. The licences on the CD (Conditions of supply of SOA boundaries and Ordnance Survey Output Area Licence) talk about a click-use licence, and a not very sraightforward OS licence covering only those SOAs that might share part of a boundary with Boundary-Line (whichever ones those are), but ONS now use the Open Government Licence, Boundary-Line is included in OS OpenData, various councils have published their SOAs as open data (e.g. Warwickshire), and these areas should be publicly available under the same licences.
- As the UK has a variety of different types of council, depending on where exactly you are, the postcode lookup now includes a shortcuts dictionary in its result, with two keys, “council” and “ward”. In one-tier areas, the values will simply by the IDs of that postcode’s council and ward (whether it’s a Metropolitan district, Unitary authority, London borough, or whatever); in two-tier areas, the values will again be dictionaries with keys “district” and “council”, pointing at the respective IDs. This should hopefully make lookups of councils easier.
Phew! I hope you find this a useful resource for getting at administrative geographic data; please do let us know of any uses you make of the site.
I’m very pleased to announce that mySociety’s upgraded point and postcode lookup service, MaPit, is public and available to all. It can tell you about administrative areas, such as councils, Welsh Assembly constituencies, or civil parishes, by various different lookups including name, point, or postcode. It has a number of features not available elsewhere as far as I know, including:
- Full Northern Ireland coverage – we found a free and open dataset from the Office of National Statistics, called NSPD Open, available for a £200 data supply charge. We’ve paid that and uploaded it to our data mirror under the terms of the licence, so you don’t have to pay – if you feel like contributing to the charity that runs mySociety to cover our costs in this, please donate! 🙂
- Actual boundaries – for any specific area, you can get the co-ordinates of the boundary in either KML, JSON, or WKT – be warned, some can be rather big!
- Point lookup – given a point, in any geometry PostGIS knows about, it can tell you about all the areas containing that point, from parish and ward up to European electoral region.
- History – large scale boundary changes will be stored as new areas; as of now, this means the site contains the Westminster constituency boundaries from both before and after the 2010 general election, queryable just like current areas.
If you wish to use our service commercially or are considering high-volume usage, please get in touch to discuss options; the data and source code are available under their respective licences from the site. I hope this service may prove useful – we will slowly be migrating our own sites to use this service (FixMyStreet has already been done and already seems a bit nippier), so it should hopefully be quite reliable.
Thanks must go to the bodies releasing this open data that we can build upon and provide these useful services, and everyone involved in working towards the release of the data. Thanks also to everyone behind GeoDjango and PostGIS, making working with polygons and shapefiles a much nicer experience than it was back in 2004.
