BBC's computer generated map of British telephone calls

The BBC have been promoting a show called “Britain from Above” in which which they take telemetry from various trackable sources and generate fancy maps of our activities and, presumably, add a thick layer of social commentary.

In the promo video linked below they show a few examples of air, land and sea movements but it’s the content at almost exactly 1 minute into the video that interests me; A traffic map of every telephone exchange in Britain tracked, as they say in the video, second by second.

This is obviously based on information from BT, so are there any mobile networks that do fancy network utilisation displays like this? Hopefully there will be more telecom eye candy in the full show.

You can check out the promo video here or, if you’re in the UK, see the whole show on Sunday 10th August at 9pm on BBC One.
