I blogged this way back in January when it first came out. It’s a World of Warcaft Online Map using the Google Maps API. They’ve added a bunch of functionality to the map, with layers you can turn on and off. It includes both “photography” as well as point layers (like where treasure is located) and polyline layers(indicating common travel paths). It’s pretty fascinating the amount of detail they’ve put into this virtual resource. I stumbled across it again via their blog.
An interesting side note is the ranking of which college campuses play more World of Warcraft than others. While it’s a trivial example, I think it’s kinda neat the continued desire to link the physical with the virtual in some for of spatially accessible manner. Plus, I like seeing that our University beats Princeton as something for once (but only by one place!)
