As this is a location-based project, perhaps a good place to start would be to visually map all of the locations in the project on one comprehensive map. I've made a rather large-scale map of the entire campus via Google Maps as a placeholder for a handmade map later. 

It should help us see the distribution of hotspots and locations across campus, so we can refine the project spatially.

We've chosen to use the entire campus as the location for the project, but we have to be careful where we decide to put content, as we might end up only using half the campus and failing in the attempt to create a believable tour.
