Britain from Above is a BBC TV series that takes a look at how Britain is interconnected in a variety of ways. The videos are interesting in not only the data that they display but also the way in which the data is visualized (The series uses data, satellite imagery and aerial videos to tell its story).
Take a look at some the clips and then take the jump to the BBC Britain from Above website.
