Hi

I'm new here and not sure this is the correct forum for real world map questions, but here goes...

When did maps of cities and town in the real world stop showing buildings (and other objects) in 3D and start having them 'flat' as we see in maps today?

e.g. This map of London from 1658 shows buildings in 3D (albeit on a fairly flat street map)

...whereas this one from 1677 is entirely flat.

I've not been able to find any before this time that show buildings flat, directly from above. Are they any examples people know of?
