A few words about Ordnance Survey – and Gordon Brown
Gordon Brown probably wouldn’t be top of many people’s lists of favourite Prime Ministers (in fact, according to many of the lists I’ve seen, he’s fairly close to the bottom) but he did do one thing during his short reign at the helm which has helped us at PCGraphics along with, indirectly, many of our UK clients.
Ok, it’s not earth shattering in the great scheme of World affairs, and it did nothing to further his career as the man who, almost single handedly, ‘saved the world.’ But in March 2010 he announced plans to free up much of the data held by Ordnance Survey (and paid for over the years by UK tax payers).
This meant that, from 1 April 2010, large tracts of O.S. data would be free to use by commercial companies such as ourselves. The idea was to give a push to growth in the digital economy.
Now, you would have thought that this was something which would have received universal acclaim throughout the cartographic world. Detailed data of the UK which we’d had to licence from O.S. on behalf of our clients which, quite often, doubled the price of a job. What’s not to like about getting that for free? Unfortunately not everyone thought so. There were a few cartographic companies in the UK who voiced their disapproval of Ordnance Survey data becoming free to use, mainly it seemed because these were companies which had built a business model based around charging clients on behalf of the O.S. to use the data.
But, enough of the doomsayers. As of April 2010 we could use O.S. data without a licence or royalties. All we needed to do was add a simple credit line at the bottom of the map, like the one at the bottom of this page.
Ok, some of the file formats that Ordnance Survey make their data available in are not suitable for home users (ESRI SHAPE files anyone? Or how about MapInfo Tab data? Or even DXF?) but for cartographic companies such as PCGraphics it opened up a whole new, much more cost effective, market.
Prior to April 2010, to get around the payment of licence fees and royalties, we would produce royalty (copyright) free mapping. This entailed acquiring aerial photography and sending cartographers out to the towns or areas to be mapped to gather all the street names etc. Remember, Google Street View of the UK was only went ‘live’ in 2009 so before then, to be copyright free, we had to physically visit every location.
So, thanks to our friend Gordon Brown (did I actually write that?), we now had a way of producing Ordnance Survey based mapping of the UK without much of the cost and red tape that we had to endure previously.
Perhaps surprisingly though, now we have Google Street View to check it against, we’ve found Ordnance Survey are perhaps not quite as accurate with their mapping as they would have us believe. Over the last few years we’ve noticed many incorrect street names and other inaccuracies with what O.S. have produced.
It’s funny because, as a cartographer, I remember being told that Ordnance Survey always used to add ‘fingerprints’ (or deliberate mistakes to you and me) to their maps to help catch those who were copying them. Now, maybe they added so many of these ‘fingerprints’ to their maps over the years that they’ve lost track of where they all are or, possibly more likely, there were quite a few unintentional errors in what they were producing? Whichever is right, it’s certainly true that Ordnance Survey maps are perhaps not quite as accurate as we were led to believe.
But hey, maybe we shouldn’t complain about Ordnance Survey maps because things could be a lot worse. A lot, lot worse actually. Imagine if Apple were in charge of UK mapping? Imagine whole towns and cities being left off the map of the UK? No, perhaps we’ll stick with the occasional error in the Ordnance Survey’s work, especially since our great friend Gordon Brown signed the papers which made large chunks of it free to use.
Three cheers for the man who ‘saved the World.’ Hip hip…….ok, let’s not go too mad.
