you can see, and many of the monuments visiblein Google earth, like the Golden Gate bridge orSydney Opera house were hand modeled. Youcan click on them to see who modeled them.Next, we added trees. Those are automaticallygenerated "generic" trees that try to approximatethe size and shape of what's visible in photos,but the/re not the models of the actual trees inthose locations.Computer algorithms aren*t as good as people atmaking 3D models, but they're tireless and veryfast, so a lot of the more recent buildings you seecome from the automatic building generationthat's mentioned in my first link. This involved alot of custom research from very smart people,special cameras, just the right aerial imagery,etc. I think that's about as much as I can say ：）・These new automated building generators wereused to fill most of the neighborhoods in SanFrancisco, for example・
