Ordnance Survey
Using OS OpenData to improve OpenStreetMap
On 1st April, Ordnance Survey released a lot of their data under an open data licence, allowing it to be used freely (with an attribution to say where it came from) and incorporated into other open data projects like OpenStreetMap.
The OpenStreetMap project started off in the UK because Ordnance Survey was so restrictive over the use of their data, so this has been a great win for the project, though the release of the data doesn't make the project any less likely to continue. This is partly because of the project's aim to create an open map (and open map data) for the whole world, and partly because in many parts of the UK, OpenStreetMap actually surpasses the level of detail that Ordnance Survey has released as part of their OpenData package.
Where the Ordnance Survey data comes in very useful for the OpenStreetMap project is in areas where we don't (yet) have much map data, as well as for areas where we do have a lot of data, for checking that our data is accurate and complete.
A little while ago I noticed that Canvey Island hadn't had much attention in OpenStreetMap, with just a few roads that had been added by a couple of users over the past two years or so. Curious about the place (and for some reason, partially imagining it to be a little like Coney Island in New York) I started to read a little about it, and thought about visiting, but the more I looked at it, the more I wanted to fill in the map. The result is below.
The OS OpenData allowed me to add roads (and most of their names), museums, libraries, pubs, schools, churches, camp sites, caravan sites, chalet villages and some natural features. Where things on the OS map didn't show names, it was often possible to pick these up from photos on the excellent Geograph project and from other research on the internet.
Once I'd got most of the tracing work done, I also got in touch with the two local contributors I had identified, one of which got back to me straight away (despite not editing the map since last year some time), and added in any extra information he could, such as the extent of parks and recreation grounds.
I think this is a great example of one open data project being advanced by the availability of data from other sources and projects.
If you want to help mapping an area (it's probably best to improve the map in areas that you know rather than mapping an area like this that you don't know that well...), just follow the instructions on the OpenStreetMap wiki.
GeoVation: share your geographic ideas
As I'm sure you know, there have been numerous innovations in the world of geography online in recent years, from Google Maps to OpenStreetMap, FireEagle to Twitter, and many more, but most (if not all) of these developments have come from commercial or open source worlds with little support from the public sector - unless you had access to large amounts of money to pay for their data.
The British Government is now starting to see the benefit of opening up data though, and I'm particularly happy to see the Ordnance Survey looking to make more data available to the public. All of which should stimulate innovation even further as it starts to make information available that was previously locked up in only commercially available datasets.
Related to this overall effort, the OS is currently promoting their GeoVation Challenge to encourage people to share their ideas for geographic innovation. There is even money up for grabs for the best business ideas proposed, designed to help get those ideas to market.
So, if you have ideas for map-based or generally geographic things you'd like to see developed, but don't have the time or knowledge to do it yourself, you can share them in the GeoVation Ideas Challenge and be in with a chance of a tour around the OS headquarters in Southampton (an interesting visit if you get the chance). On the other hand, if you have a business idea, and are prepared to put the work in to get it going, you can share your idea in the GeoVation Awards Challenge and be in with a chance to win up to £10,000 to help get your venture off the ground.
If you're interested in taking part, you will need to act fast as the closing date for entries is 4 January 2010. Best of luck!
Weekend mapping projects
I've been thinking for a month or so now about OpenStreetMap and things that I can do to help out the project - besides the data collection and mapping I've been doing since the start of the year.
It all began when I was wondering what the difference in cost would be to an organisation (Futuresonic in this case) between licensing Ordnance Survey data and actually going out and mapping an area themselves.
I wouldn't say the two data sources are directly comparable, but both could meet a given need for an organisation. Often the detail of the OS data would be overkill for orangisations wanting simple maps for context, and potentially very expensive depending on how it's used. OpenStreetMap data, on the other hand, may not have as good coverage - though with time and energy it can be easily extended - but it would be available without the cost.
So, one of the ideas that I've come up with recently is for weekend mapping projects. The basic idea of a weekend mapping project is that I would offer organisations, groups or individuals a weekend of my time to map as much of an area as I could feasibly do in a whole weekend (with extra time afterwards to convert the GPS traces and any annotations such as road names into usable map data).
I think it would be fair to ask for those people to pay for low cost flights from my base to their location, bike rental or something for the actual GPS track collection, and a small amount to cover some cheap accommodation and food for the time I'm there. In return they get free map data onto which they should be able to build, adding their own information and styling to make the maps unique to their own needs.
Why would I offer my limited free time to do this though? Well, quite simply, I really enjoy travelling and seeing new places. I'm also really interested in the idea of open, reusable, community-created content, especially in the form of OpenStreetMap for geographic data, but also Wikipedia for general reference information. So, if I can travel to new places and map them out to help expand the OpenStreetMap dataset, it's hitting on both of those desires in one go.
If anybody is interested, please do get in touch and we can talk through the details.
Updated 15 July with link to page on OSM wiki. Some other community members are interested too, and the more the better as that means sponsors would have a better chance of finding someone close to them, and so have lower travel costs.
