an interesting observation
Jul. 16th, 2009 08:47 amI've been building a map in GoogleMaps, and I had it set to most of Scotland. I idly flipped on "traffic" and saw that bits of the Central Belt lit up, mostly green (it's the middle of the day, so that makes sense) but nowhere else much. I can see that making sense; there's probably less traffic in other parts of the country but also less infrastructure for reporting traffic.
Then I scrolled the scale out to show all of the UK. The image is kind of striking. There's traffic data that run right the way from Penzance to Newcastle, but it stops dead at the borders of England. Funny.
Then I scrolled out further to see all of western Europe. *No* data anywhere, except for France. So this is clearly an artifact of information-sharing agreements (I'm sure Germany has both traffic and the ability to monitor it).
