Hi there -- I don't suppose anyone knows what those maps are called that are sort of like pictures of buildings etc (argh! I can't even explain what I mean!).
So instead of everything being flat and seen from above, like our maps, these show the shapes of the buildings when seen sort of from the side/ above?
