1. A computer-implemented method, comprising: receiving, by a computing device, navigational information that defines a route; sensing motion of the computing device along the route; displaying, based on the sensed motion of the computing device along the route, overhead map or satellite images that correspond to respective locations of the computing device along the route; identifying a current traveling speed of the computing device along the route; determining that the current traveling speed of the computing device is less than a threshold traveling speed; and in response to determining that the current traveling speed of the computing device is less than the threshold traveling speed, causing the computing device to change from (a) displaying the overhead map or satellite images that correspond to the respective locations of the computing device along the route to (b) displaying one or more digital photographic images that were captured at street level and that correspond to one or more locations of the computing device along the route.
