Abstract

A method of operating a navigation system determines a route between an origin and a destination and provides a photographic image showing a geographic area through which the route passes. The photographic image is obtained from a geographic database, and the photographic image shows the geographic area from a land-based viewpoint. The method overlays a route highlight on the photographic image identifying a path to be traveled. The route highlight extends along the path for a distance visible in the photographic image.

Claims

1. A method of operating a navigation system comprising:

determining a route between an origin and a destination;

providing a photographic image showing a geographic area through which said route passes, wherein said photographic image is obtained from a geographic database, wherein said photographic image shows the geographic area from a land-based viewpoint; and

overlaying a route highlight on said photographic image identifying a path to be traveled, wherein the route highlight extends along the path for a distance visible in the photographic image.

2. The method of claim 1 further comprising:

providing labels on said photographic image.

3. The method of claim 1 wherein said photographic image is associated with road segment data in the geographic database.

4. The method of claim 1 wherein said photographic image is associated with location information in the geographic database.

5. The method of claim 1 wherein said route highlight includes a symbol indicating a feature of the path.

6. The method of claim 1 wherein said symbol indicates handicap accessibility.

7. The method of claim 1 wherein said photographic image provides an angle of view greater than 180 degrees.

8. A navigation system comprising:

a geographic database;

a processor; and

a guidance application executable on said processor to obtain a photographic image from said geographic database and to overlay a route highlight on said photographic image;

wherein said route highlight extends along a path shown in said photographic image for a distance visible in said photographic image, wherein said photographic image provides a land-based view.

9. The system of claim 8 wherein said guidance application displays said photographic image with said route highlight on a display.

10. The system of claim 8 wherein said guidance application places a text label on said photographic image to identify a point of interest visible is the photographic image.

11. The system of claim 8 wherein said photographic image is associated with road segment data in the geographic database.

12. The system of claim 8 wherein said photographic image is associated with location information in the geographic database.

13. The system of claim 8 wherein said route highlight includes a symbol indicating a feature of the path.

14. The system of claim 8 wherein said photographic image provides an angle of view greater than 180 degrees.

15. A method for providing navigation-related information comprising:

determining a location; and

providing a photographic image of a geographic area corresponding to said location, wherein said photographic image provides a land-base viewpoint, wherein said photographic image provides an angle of view greater than 180 degrees, wherein said photographic image is obtained from a geographic database, wherein in said photographic image shows a route highlight that extends along a path shown in said photographic image for a distance visible in said photographic image.

16. The method of claim 15 wherein the photographic image includes a label identifying a point of interest.

17. The method of claim 15 wherein the photographic image is comprised of at least two photographs having angle of view less than 180 degrees stitched together.

18. The method of claim 15 wherein the photographic image includes advertising.
