It's surprisingly tricky to do, because the out-of copyright map doesn't show the boundaries very clearly, and things have been chopped around with re-organisations of local government. Much of the northern boundary of the authority follows the Thames, and the area around the eastern boundary is mapped on OSM to a very detailed level, so there is a lot of other data that you don't want to mess with.
Anyway, I think I've got it reasonably accurately now. Others are doing a sterling job in the rest of the country, so an open map of England's administrative boundaries is beginning to come together. Progress is nicely tracked here.
I'm a bit conflicted about campaigns like this and this to release more public data into the public domain. On the face of it, it's a fine principle that taxpayers should have free access to data that they have already paid to collect. But then shouldn't those with a special interest or need for the data contribute more of the cost than everyone else? Somewhere there is a sensible line to be drawn, and I'm not sure where it is.
But when it comes to electoral boundaries, I can't help feeling that they should all be released into the public domain on principle, not on economic grounds. Anyway, I've amused myself for a few hours setting a little bit of data free. There are worse ways to waste a rainy Saturday morning.
