In some example embodiments, a computer system accesses service data and sensor data for a plurality of requests for a transportation service associated with a place, with the service data comprising pick-up data indicating a pick-up location and drop-off data indicating a drop-off location, and the sensor data comprising satellite signals indicating a pick-up path or a drop-off path, with the satellite signals each having a corresponding signal strength. The computer system determines a transition geographic location for the place based on the signal strengths of the satellite signals. ## Claims ### Claim 1 A computer-implemented method comprising: accessing, by a computer system having at least one hardware processor, corresponding sensor data for each one of a plurality of requests for a transportation service comprising delivery of an item to or from a place, the corresponding sensor data comprising a plurality of satellite signals indicating a path of a mobile device of a provider of the transportation service corresponding to the one of the plurality of requests, the path having been walked by the provider before entering or after exiting a vehicle used by the provider to provide the transportation service;
