Claim One:
1. A computer-implemented method of generating position estimates of a trackee at a location, the method being implemented by a computer that includes a physical processor, the method, comprising: obtaining, as input, tracking data for the trackee obtained from inertial sensors, wherein the tracking data includes a collection of tracking points forming a tracking path of the trackee, and wherein each tracking point includes at least two-dimensional location coordinates; causing a map of the location to be displayed, via a graphical user interface associated with the computer, the map including one or more building features; generating position estimates for the trackee by dividing the tracking path into polygonal path segments of tracking points and correlating a polygonal path segment to a building feature to reduce tracking errors associated with the inertial sensors responsive to a determination that the polygonal path segment matches the building feature; and causing the generated position estimates to be displayed on the map.
