Looks great. A few points:<p>- They used new imagery from planes to do this, not the existing streetview imagery - I guess that means optical matching of the kind needed to do this (make a model from streetview imagery) is still a ways off.<p>- 3d maps has been done like this already (by bing and others), though this looks a better resolution.<p>- As someone who works with city spaces - can I use the 3d data? How can I download it or who do I have to pay?
