These building footprints, complete with height detail, are algorithmically created by taking aerial imagery and using computer vision techniques to render the building shapes.
I could have guessed that before the punchline. And it's not that difficult to add for a company with tens of billions in cash. What are you doing, Apple? Fix your OS and Maps!
Lenses don't work that way, surely. Any image taken directly downwards will include angled elements offset at a greater angle away from the centre line.
