This is different than what Microsoft is doing. Microsoft is getting data from municipalities about how tall a building is, and then generating a generic building that's the right shape and as tall as the data says it is. You can see what that looks like in the article; look closely at the Melbourne cricket ground before the community fixed it, and it's just an oval building that looks like a generic multi-story apartment building. That's their algorithmic generation when they don't have 3D data from aerial photos. (There are also fun anomalies, like the world's tallest building being as wide as a single house because someone typo'd the number of floors in the official records.) As far as I can tell, Google isn't doing that. They only have 3D buildings where there are aerial photos that can see the walls of the building, they then use that data to construct a 3D model. |
