This is how Google Maps (or earth, to be precise) used to have 3D models in it. Everyhting was handcrafted.
Modeling was partly outsourced for anyone willing to do it with Google Sketchup, back when Google still owned it. It however, was really labour intensive and one could see a lot of human mistakes.
Using aerial images to generate 3D models is way cheaper and faster. I’m interested to see where this project is going, but i’m a bit sceptical for a long time success.

- prashnts 7y agoI used to contribute to Google's 3D Warehouse (which was acquired by Trimble/Sketchup) to add few 3D buildings around Delhi in Google Earth. Teenager me was quite heartbroken when google switched to the auto generated 3D models, but clearly, as you said, manual modeling wasn't feasible at world scale. I was most proud of a railway bridge in the Himalayas that ended up in Google Earth for a while. https://3dwarehouse.sketchup.com/model/8f5b83eb14588a6dd3816365deb2b4a2/Chenab-River-Railway-Bridge https://3dwarehouse.sketchup.com/model/8f5b83eb14588a6dd3816...
