Easy way to build a 3d map based on real world?

So, I wanted to make a shooter that’s set in a real world location(specifically, a university campus in Brazil). Is there an API or some other easy-ish way to build that map(doesn’t have to have buildings in it, if it has the positions of where the buildings should be that’d already be something) aside from building it from scratch?
Thanks!

This asset that does exactly that!

Enjoy developing your game :wink:
