Comment An Old Vietnam Veteran Says It Can't Be Done (Score 2, Interesting) 351
As an old photointerpreter from the Vietnam era, and a fanatic regarding aerial photography, I can assure you that civilian satellite-based cameras do not have the resolution to read license plates. There was once a concept of "infinite resolution film", but that was always theoretical and, if you think about it, could never be accomplished. As was said above, the cameras are earth-based. Only the speed computation using the GPS system is satellite-based.
