Check out this virtual image of Berkeley (my old college stomping ground).
Avideh Zakhor and her research team made this virtual map of the city in 4.5 hours. That’s 30 minutes of driving time, with a high powered laser strapped to your car, and four hours of data processing.
If you ask me, it kicks the crap out of Google’s Satellite images, if only because its up to date. This New Scientists article, however, makes it sound like the application of this mapping won’t be to amuse yourself in the cubicle, but to help soldiers conduct urban warfare.
