1. A method for a computing device to determine a route, the method comprising:
- determining a sun position relative to the route based on a current position of the computing device, a current date, and a time of day to determine whether visibility would be impaired by a rising or setting sun substantially aligned with at least a portion of the route;
determining weather conditions along the route;
determining cloud conditions, based on weather conditions, including whether clouds would mitigate a visibility-impairing effect of the rising or setting sun substantially aligned with the at least a portion of the route;
determining using a processor whether to provide alternate routing based on both the sun position and the cloud conditions; and
displaying, on the computing device, a weather-specific digital photograph of a point of interest along the route, the photograph being determined based on the determined weather conditions along the route.

Abstract
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.

7. A non-transitory computer-readable medium comprising instructions in code which when loaded into a memory and executed by a processor of a computing device cause the computing device to:
-
determine a sun position relative to the route based on a;
current position of the computing device, a current date, and a time of day to determine whether visibility would be impaired by a rising or setting sun substantially aligned with at least a portion of the route;determine weather conditions along the route; determine cloud conditions, based on the weather conditions, including whether clouds would mitigate a visibility-impairing effect of the rising or setting sun substantially aligned with the at least a portion of the route; determine whether to provide alternate routing based on both the sun position and the cloud conditions; and display, on the computing device, a weather-specific digital photograph of a point of interest along the route, the photograph being determined based on the determined weather conditions along the route. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computing device comprising:
-
a position-determining subsystem for determining a current position of the computing device; a user input device for receiving a destination location; a processor operatively coupled to a memory to execute a navigation application for determining a route to the destination location in response to user input received via the user input device, the navigation application determining a sun position relative to the route based on the current position, a current date and a time of day to determine whether visibility would be impaired by a rising or setting sun substantially aligned with at least a portion of the route, the navigation application further determining cloud conditions based on weather conditions, including whether clouds would mitigate a visibility-impairing effect of the rising or setting sun substantially aligned with the at least a portion of the route; a radiofrequency transceiver for obtaining the weather conditions; and a display for displaying a weather-specific digital photograph of a point of interest along the route, the photograph being determined based on the obtained weather conditions along the route, wherein the navigation application executed by the processor determines whether i to provide alternate routing based on both the sun position and the cloud conditions. - View Dependent Claims (14, 15, 16, 17, 18)
