When they don't.fascinating disaster ensues. When 2D images overlay nicely on the 3D terrain data, these cues help everything look normal. The view is further complicated by the shadows in the aerial images, which cue our brains to look for depth. In other words, the bridge appears to follow the terrain that it actually goes over. When the flat image is projected onto this 3-dimensional surface, the bridges are projected down onto the terrain below the bridge. However, the 3D models in Google Earth contain only the information for the terrain-the landmass or the bottom of the ocean. ![]() Basically, the satellite images are flat representations in which you only see the topmost object-in this case you see the bridge, and not the landmass or water below the bridge. Yet something encoded in us long ago reacts when we see the world at this unprecedented scale. Humans have only been able to see the planet from space for the last 50 years. The images are the result of mapping a 2-dimensional image onto a 3-dimensional surface. Earth View is a collection of thousands of the most striking landscapes found in Google Earth. So what's really happening in these pictures? Here’s Valla's explanation: ![]() Where Google Earth’s mapping has gone awry, as you may have seen in a post on Boing Boing Has discovered 60 strange, beautiful scenes
