Zusammenfassung:	A method and system for improving route finding are described. Aspects of the disclosure determine a bearing for a client device using a compass. The determined bearing is used to optimize route finding operations performed by the client device. The bearing may be mapped to a road graph and used in conjunction with a location of the client device to determine an efficient route to a destination. For example, aspects of the method and system may identify a nearest turn in the direction the client device is traveling without the need to obtain multiple location readings to identify a direction of travel.
