More on How Google Does 3D
Martin Daly (Lost in Spatial blog) summarizes Ed Parsons latest talk (at BCS) and I grabbed these tidbits about how the 3D building data is captured.
- Street View uses LIDAR to get the building shapes, for the fancy navigation, and bespoke cameras because the high number of images captured broke the shutters in consumer digital cameras. [I’m almost tempted to make an analogy with consumer slippy maps and bespoke GIS there, but I’ll refrain.]
-Google use their own plane to capture the oblique images for Building Maker.
