Wikia Maps - Create and collaboratively annotate maps about anything

"Wikia Maps is a fan-authored mapping tool that will allow you as a user to create maps of real or fictional places and share them with others. Some highlights we've spotted so far include Westeros from Game of Thrones, Dark Souls 2 Locations and of course the Millenium Falcon."

This has comparison's to Genius' vision to annotate the world. I'm not a Star Wars geek but this annotated Millennium Falcon is super rad.
