Abstract

A method of displaying a navigation map includes determining a route of a vehicle. Three-dimensional data is received. The data is associated with buildings that are disposed within a geographic area. The geographic area includes the route of the vehicle. At least one of the buildings in the data that is adjacent to at least one street of the route is rendered in a first opaque visual style. All of the buildings in the data that are nonadjacent to at least one street of the route are rendered in at least one second visual style different from the first opaque visual style.

Claims

1. A method of displaying a navigation map, comprising the steps of:

determining a route of a vehicle, the route including at least one street segment on which the vehicle travels;

receiving three-dimensional data associated with objects that are disposed within a geographic area, the geographic area including the route of the vehicle;

rendering in a first opaque visual style at least one of the objects in the data that is adjacent to at least one said street segment of the route; and

rendering in at least one second visual style all of the objects in the data that are nonadjacent to each said street segment of the route, the at least one second visual style being different from the first opaque visual style.

2. The method of claim 1 wherein the objects comprise buildings.

3. The method of claim 2 wherein at least one but less than all of the buildings that are adjacent to at least one said street segment are rendered in the first opaque visual style.

4. The method of claim 1 wherein the first opaque visual style is characterized by at least one of a nonphotographic style, a distinctive color tone, lighting effects, shading effects, and distinctive outlining of objects.

5. The method of claim 1 wherein the second visual style is characterized by at least one of a photographic style, black and white line drawings, and grayscale drawings.

6. The method of claim 1 wherein the at least one object that is rendered in the first opaque visual style is automatically chosen at least partially based upon a quantitative parameter provided by the user.

7. The method of claim 6 wherein the quantitative parameter comprises one of:

a fixed percentage of the objects to be rendered in the first opaque visual style;

a maximum percentage of the objects to be rendered in the first opaque visual style;

a fixed number of the objects to be rendered in the first opaque visual style per unit length of the route; and

a maximum number of the objects to be rendered in the first opaque visual style per unit length of the route.

8. The method of claim 1 comprising the further step of displaying an image including the objects rendered in the first and second visual styles on a display screen within the vehicle.

9. The method of claim 8 wherein a view of the route in the displayed image is partially occluded by at least one of the objects.

10. A method of displaying a navigation map, comprising the steps of:

determining a route of a vehicle;

receiving three-dimensional data associated with objects that are disposed within a geographic area, the geographic area including the route of the vehicle;

receiving a selection from a user of a category of the objects;

rendering in a first opaque visual style at least one of the objects that is within a threshold distance of the route and that is in the selected category; and

rendering in at least one second visual style all of the objects that are beyond the threshold distance from the route or that are out of the selected category, the at least one second visual style being different from the first opaque visual style.

11. The method of claim 10 wherein the objects include buildings, the selected category comprising at least one of:

hotels;

restaurants;

buildings having at least one retailer as a tenant;

public buildings;

buildings having a predetermined lighting characteristic; and

buildings having a predetermined dimensional characteristic.

12. The method of claim 10 wherein the threshold distance comprises being adjacent to a segment of street that is included in the route.

13. The method of claim 10 wherein the first opaque visual style is characterized by at least one of a nonphotographic style, a distinctive color tone, lighting effects, shading effects, and distinctive outlining of objects.

14. The method of claim 10 comprising the further step of displaying an image including the objects rendered in the first and second visual styles on a display screen within the vehicle.

15. The method of claim 14 wherein a view of the route in the displayed image is partially occluded by at least one of the objects.

16. A method of displaying a navigation map, comprising the steps of:

determining a route of a vehicle;

receiving three-dimensional data associated with objects that are disposed within a geographic area, the geographic area including the route of the vehicle;

receiving a selection from a user of a category of the objects;

rendering in a first opaque visual style a subset of a group of the objects, each of the objects in the group being within a threshold distance of the route and being in the selected category, the objects in the subset being automatically chosen based upon a quantitative parameter provided by the user; and

rendering in at least one second visual style the objects that are out of the subset of the group, the at least one second visual style being different from the first opaque visual style.

17. The method of claim 16 wherein the quantitative parameter comprises one of:

a fixed percentage of the objects to be rendered in the first opaque visual style;

a maximum percentage of the objects to be rendered in the first opaque visual style;

a fixed number of the objects to be rendered in the first opaque visual style per unit length of the route; and

a maximum number of the objects to be rendered in the first opaque visual style per unit length of the route.

18. The method of claim 16 wherein the threshold distance comprises being adjacent to a segment of street that is included in the route.

19. The method of claim 16 wherein the first opaque visual style is characterized by at least one of a nonphotographic style, a distinctive color tone, lighting effects, shading effects, and distinctive outlining of objects.

20. The method of claim 16 comprising the further step of displaying an image including the objects rendered in the first and second visual styles on a display screen within the vehicle, wherein a view of the route in the displayed image is partially occluded by at least one of the objects.
