I 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...
