The BBC have got a new series on called Britain From Above - part two is on BBC1 tonight at 21:00 but you can catch up with iPlayer.
I watched it last week and I thought it was really interesting; think of Google Earth, but with some explanation of what you’re actually seeing.
Anyway, here’s the page from the BBC site:

Even if you don’t watch the program, the site is great and if you can’t manage too much reading, there are some good pictures under the Photography section.
