There is an interesting project called Placing Literature that aims to map out the correspondence between real and fictional places. The work in progress is a bit top-heavy with contemporary and anglophone works (who wouldn't mark Dresden with Slaughter House Five or Nordhausen with Gravity's Rainbow, unless they have yet to discover it?), but invites anyone's push-pins. What real-make-believe settings would you add? I wonder how a real-world map might figure in a universe, some cannon of works that only reference humanity and human-conventions sparingly.
