1. A method comprising, at a mobile device:
- tracing a path of movement of said mobile device from a starting point;
detecting an intersection of said traced path of movement with one or more locations of a routing graph defining feasible movement within an area; and
estimating a contiguous route from said one or more locations of said routing graph to said starting point based, at least in part, on said detected intersection and said traced path of movement.

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.
