We see these overlays becoming important units of shared information among users. One overlay might be all bus stops in a city or area. Another might be a list of hazards. Overlays of good restaurants, government services offices, a campus building directory and wheelchair accessible shops are all examples of geographic data of interest to groups of people. Associated with overlays are paths.
Paths are routes from one point to another.
They are typically made up of a series of waypoints traversed in a certain direction. For instance, a short path of interest in the vicinity of Arkenstone is the path from the bus stop on Java to Arkenstone. The first waypoint is the bus stop itself, the second is the corner of Java and Borregas, the third is the corner of Caspian Court and Borregas and the final point is Arkenstone itself. Paths are aids to orientation. A user who is interested in traveling to a new destination can use Atlas Speaks to find the destination.
