The Null Device

One of the things that Britain does better than anyone else is postcodes; while most countries' postcodes give you an area the size of a suburb or town, the six or seven letters of a Royal Mail postcode give you a segment of a street, with enough information to find the place the code refers to. This allows sites like the Transport for London Journey Planner to tell you exactly how to get from one postcode to another.

There is a problem with this, though; the postcode data is not free, but is owned by Royal Mail, who monetise the hell out of it. If you wish to use the database for your own purposes, doing so will cost you a few thousand pounds a year. (The fact that your taxes may have paid for the system to be drawn up doesn't enter into the argument.)

Anyway, this has gotten up the nose of a number of open-geodata activists, who are doing something about it: they're collecting their own data mapping points to postcodes, and using this to draw up freely usable and distributable maps of postcode areas. Free The Postcode! is aiming to do this at a high level of accuracy, soliciting input from people with GPS receivers; meanwhile, New Popular Edition Maps is using a 1940s-vintage map of England and Wales (Scotland and Northern Ireland may come later) to allow people to click on where their homes are and enter the postcodes. Since this is inherently less accurate (the map is of fairly low resolution, and the process depends on matching shapes of streets), they're only concerned with the prefixes at this stage. The data produced will be released into the public domain.

The UK's Ordnance Survey, the government agency which uses taxpayers' funds to create incredibly detailed maps and then licenses them under prohibitive licensing terms and steep fees, seems to be thawing to open access to its data, and is experimenting with a Google Maps-style JavaScript interface, to be named "OpenSpace". Note that if it is released, it will only be for noncommercial use, and the actual data itself won't be made public. I wonder how much this is a result of pressure from OpenStreetMap and other guerilla mappers encroaching on its monopoly.

In Britain, there is little free map data. There is an excellent map of the whole of Britain, assembled by the government's Ordnance Survey, but, in line with Thatcherite-Blairite ideology, which holds that not extracting the maximum profit is a grievious dereliction of duty, this is commercial and expensive. (In contrast, the United States Geographical Survey's maps are in the public domain, the reasoning being that, as they were assembled with public funds, they belong to the public.) A group of mapping geeks and free-culture activists under the banner of OpenStreetMap are working to reverse this by creating their own maps; they have a wiki-like system to which volunteers with GPS units can upload traces of streets they have walked down and such. This weekend, they are having a working bee of sorts, intensively mapping the Isle of Wight. More than 30 volunteers will descend on the island, walking its many paths with GPS units and uploading their traces to the wiki; of course, the more the merrier, so if you have a GPS unit and a belief that information wants to be free.

It is hoped that this project, and the OpenStreetMap project in general, will force a sea change in the ownership of geographical data in the UK, much in the way that the Sanger Institute's human-genome sequencing effort in Cambridge made it unfeasible for Celera Genomics to exercise proprietary control over the human genome.

Throughout its existence, the Soviet Union went to great efforts producing extremely accurate maps of the entire world, often containing information omitted from local maps. The information was often gathered by surreptitious means, especially in Western countries. And because the Commies didn't believe in intellectual property and the aggressive monetisation of all possible rights, these maps are now claimed to be in the public domain (though they are currently illegal in the UK, because of alleged copyright violations; the articles linked on the page, however, argue that the maps did not use Ordnance Survey data, though the Ordnance Survey still argues that the maps illegally undermine its monopoly), which could mean that, should digitised versions find their way onto the net, they may prove invaluable to open mapping projects.

And here is a Pravda article mentioning the alarm that occurred in Sweden when they found out that the Russians had better maps of Sweden than they did, and allegations that a lot of the data was gathered by KGB agents posing as the children of Swedish Communists who moved to the USSR in the 1930s and then disappeared in Stalin's purges.

Impressive hack of the day: turning a Nintendo DS into a GPS-enabled map viewer, using a GPS unit wired to its serial port and a CompactFlash card full of map tile images purloined from Google Maps.

The use of downloaded Google Maps tiles is interesting; I wonder how long until someone writes a map viewer for PalmOS which uses these, effectively cutting into the market share of programs like Tube (which have limited coverage, and often annoying qualities such as being unable to scroll between map tiles; a pain when you're looking for somewhere just off the map, or in the intersection between two tiles). Then again, Google may be able and/or obliged to use the DMCA against any software which attempts to use its map tiles in this fashion (though I am not a lawyer).

Last night, I went to Dorkbot). It was a bit of a mixed bag; the presentation on London Free Map (a sort of geospatial Wikipedia, consisting of people with GPS units walking the lengths of streets to build up a GFDL/CC-licensed map of London and break the Ordnance Survey monopoly; connected with OpenStreetMap) was interesting, as were some of the "minidorks", including one by a chap who put a Wacom tablet on a guitar-like mount and used it to make noise with Max/MSP, and one by an American who built a 3D voxel display for Burning Man, using 729 microcontrollers, RGB LEDs and ping-pong balls, and an Ethernet printer server to control them). Others left a bit to be desired; the architecture student who started his with footage of the World Trade Center attack and went on to talk about the acoustics of spaces, sticking microphones into his mouth and filling latex balls with white noise, seemed a bit on the random side, while the presentation about the possibility of a bicycle that folds into an umbrella-sized package had little more than hastily-made Microsoft Paint drawings to it. There was also an intriguing-looking installation on the table, consisting of a brain-shaped set of neon tubes, a red vintage telephone and a Radio Shack speaker box, though the person operating it couldn't make it, and attempts to demonstrate it over the phone proved inconclusive (all it did was flicker, and the mobile phone interference drowned out what the guy at the other end was saying).

A Canadian company has devised a universal postcode system. With this system, a 10-character code, of the form "W2B00 8P2H0" uniquely denotes an area measuring approximately one square metre anywhere on the earth's surface. The Natural Area Coding System itself is quite simple; each character is a base-30 digit, and the two groups of characters refer to longitude and latitude as fractions of 360 and 180 degrees respectively.

This all sounds like one of those brilliantly original ideas, like Esperanto or Metric Time, which, for all their ingenuity, come up face-first against the brick wall of pragmatism and inertia, people being creatures of habit and all; except for two things: firstly, in the age of GPS, Natural Area Coding System codes will be easier to determine than traditional post codes, as there will be no maps or databases to look up, and also no questions of changing boundaries (as happens from time to time, for example when resident groups or landlords lobby to redraw the boundaries so their properties aren't in Footscray or South-Central LA or somewhere similarly insalubrious). And secondly, Microsoft are backing the idea, and plan to integrate it with their MapPoint map service. (Perhaps they hope that they can use it to lock customers into depending on Microsoft technologies or something? I wonder if it's patented.)

NACS could eventually become a world-wide postcode, replacing legacy postcode systems devised in the pre-GPS era. It would probably happen with shipping/courier firms utilising the codes internally, and businesses which deal with them putting them on their details, and finally postal services phase out the pre-GPS system and adopt this. Of course, if someone detonates an EMP bomb in the high stratosphere and fries all the GPS satellites (or if the Americans stop being our friends), we're all fucked; but if all the satellites disappear, we'd have more important things to worry about.
