With last months launch of Google Earth 5.0 much “mainstream” interest was focused on the capability to view under the ocean, and of course to begin the search for the lost city of Atlantis 🙂
For many however, myself included, the most important new capability is the ability to view historic images from the Google archive of satellite and aerial imagery.
Early days of course, but the potential to view history in this way has massive potential as illustrated by this image of Wembley Stadium in London. As you can imagine the back office system needed to deliver this are substantial, but the limiting factor remains access to imagery from around the world.
As to be expected by now the greatest availability is in the United States where the enlightened federal data policy means that it is possible to view Mountain View Ca. from the late 1940s — fantastic for viewing the development of the city from farmland to Silicon Valley.
Similar imagery of course was acquired at the same time in Europe, if would be wonderful to see it also made available..
