1. A method comprising:
obtaining location data representing a first location of a mobile device, wherein the location data for the mobile device is taken at a first sampling rate;
determining, based on a comparison of the location data to a threshold, the location data is insufficient to detect a direction of travel for the mobile device; and
triggering an increase in location data sampling from the first sampling rate to a second sampling rate in response to determining the location data is insufficient to detect a direction of travel for the mobile device.
