An explanation of how Google uses airplanes, multi-camera rigs, and photogrammetry to construct highly detailed 3D models for Google Earth.

Google Earth is the most photorealistic, digital version of our planet. But how?! Where do the images come from? How are they they put together? And how often are they updated? In this video, learn about the pixels, planes, and people that create Google Earth’s 3D imagery.

They fly their own planes these days. link Too bad it's a video. Fast forward about 2 minutes. Or: link to this video Fly plane. Zig zag. 5 cameras, then photogrammetry. StreetView, from planes.

I have been spending some time on the Virtual Reality version of Google Earth, and it is amazing to see the world in 3D from inside. Here there is a video on how Google creates the 3D for Google Earth: link to this video I hope to see more of this technologies as it is great to visit places without leaving home.

On “Google deploying planes over cities for 3D maps (2012)”

Hmm, I'm curious about your first claim! I can't find anything more recent than ~20170, but they were still using Airplanes to gather imagery for the 3D maps. I'm pretty sure this is still the case, as urban area resolution is way higher than available non military satellite imagery. 0: link to this video
