The Cartographer Who Mapped Out Gotham City (smithsonianmag.com)

This reminds me of OpenGeofiction: "a collaborative platform for the creation of fictional maps." http://opengeofiction.net/#map=5/51.495/-0.088

Perhaps someone can port this so that we can all modify it for good measure.

It's impressive that the Smithsonian has added ads to cutting and pasting of the title. What a perfect way to motivate people not to share the link..

Its one of the hallmarks of a great story, a consistent world to host it in. That does create a level of authenticity that is felt more than read. I really enjoyed all of Tolkien's maps and even the maps in the Thomas Covenant series.

It's reached the point where Gotham really is one of the main characters in the Batman stories, if not the main character.
