This sounds like a very appropriate solution since GPS and WiFi are often only intermittently available indoors. Mapping programs are just starting to gather information about the insides of structures to make sense of tghe computed routes. It would be interesting to see the accumulated errors before a waypoint resolve after encountering the next one. I'm guessing the dead reckoning mapped route rescales to align with the known waypoints.
