Back in March, we posted a demo of C3 Technology’s extremely cool 3D maps. The reconstructions of landmarks and buildings are created by a technique (as I understand it) similar to the Kinect hack we posted that uses compiled depth and parallax data to continually build and refine a 3D model of whatever it’s looking at. C3’s version obviously works on a larger scale and thus has different strengths and requirements, but it’s almost completely automated as long as you can afford to send a plane or copter up with the equipment.They were bought earlier this year, but the purchaser was not known at the time. 9to5Mac has been informed that the buyer was none other than Apple. It makes sense: Apple has bought two other mapping companies, Placebase in 2009 and Poly9 in 2010. It seems beyond a doubt that they are deep into a skunk works operation to revamp their maps.
