A computer-implemented navigational method includes transmitting, from a mobile computing device to a computer server system, data that can be used to determine a start point and an end point of a trip. The method also includes receiving navigational information defining a route between the start point and the end point, and a plurality of digital photographic images that have previously been taken along the route, sensing motion of the mobile computing device along the route, and displaying updated images from the plurality of images that substantially match a geographic position of the mobile computing device along the route.
