Navigation System And Method For Determining A Route Based On Sun Position And Weather

A method for a computing device to determine a route entails determining a sun position relative to the route, determining weather conditions along the route, and determining whether to provide alternate routing based on both the sun position and the weather conditions. In one implementation, time-specific and weather-specific digital photographs of points of interest along the route are downloaded for display on the device when the device is located at or near the points of interest.
