Abstract
Disclosed are systems, methods, and devices for aligning a path of movement of a mobile device with an indoor routing graph. In one particular embodiment, a mobile device may trace a path of movement from a starting point to a point of intersection with a routing graph that defines feasible movement within an area. Responsive to a detecting a point of intersection, a mobile device may estimate a contiguous route from one or more locations of the routing graph to a starting point.
