Abstract

A graphical user interface for graphically managing the navigational usability of an interactive map is described. In one embodiment, the graphical user interface includes a layer hierarchy having a first layer and a second layer. The graphical user interface also includes a first display range bar associated with the first layer and configured to show a range of map scales at which the first layer is displayed in the digitized map. In addition, the graphical user interface includes a second display range bar associated with the second layer and configured to show a range of map scales at which the second layer is displayed in the digitized map.

Claims

1. A system comprising:

a graphical user interface configured to organize and manage the layers of a digitized map, the graphical user interface including;

a layer hierarchy including a first layer and a second layer,

a first display range defining a first set of map scales at which the first layer is displayed in the digitized map, and

a second display range defining a second set of map scales at which the second layer is displayed in the digitized map; and

a display device displaying the graphical user interface.

2. The system of claim 1, wherein the graphical user interface further includes a first graphics style representing a first map feature included in the first layer.

3. The system of claim 2, wherein the graphical user interface further includes a first summary bar corresponding to the first layer and spanning the first display range.

4. The system of claim 1, wherein the graphical user interface further includes a first graphics style and a second graphics style, wherein the first graphics style and the second graphics style represent a first map feature included in the first layer.

5. The system of claim 4, wherein the graphical user interface further includes a first display range bar corresponding to the first graphics style and the second graphics style and spanning the first display range.

6. The system of claim 4, wherein the graphical user interface further includes a first summary bar corresponding to the first layer and spanning the first display range.

7. The system of claim 4, wherein the first display range includes a first subset of map scales and a second subset of map scales, and the graphical user interface further includes a first display range bar corresponding the first graphics style and spanning the first subset of map scales, and a second display range bar corresponding to the second graphics style and spanning the second subset of map scales.

8. The system of claim 1, wherein the layer hierarchy further includes a first node under which one or more layers of the digitized map are organized.

9. The system of claim 8, wherein the graphical user interface further includes a first summary bar corresponding to the first node and spanning a third display range defining a third set of map scales, the third set of map scales including each map scale at which any layer organized under the node is displayed in the digitized map.

10. The system of claim 8, wherein the first node is a layer group or a sub-layer group.

11. The system of claim 1, wherein the first layer and the second layer are arranged in the layer hierarchy based on the order in which they are superimposed when the digitized map is rendered.

12. A method for graphically organizing and managing layers of a digitized map, the method comprising:

generating a hierarchical display of layers that includes a first layer and a second layer;

displaying a first display range defining a first set of map scales at which the first layer is displayed in the digitized map based on user input; and

displaying a second display range defining a second set of map scales at which the second layer is displayed in the digitized map based on user input.

13. The method of claim 12, further comprising the step of displaying a first graphics style and a second graphics style, wherein the first graphics style and the second graphics style represent a first map feature included in the first layer.

14. The method of claim 12, wherein the hierarchical display of layers further includes a first node under which one or more layers of the digitized map are organized.

15. The method of claim 14, wherein the first node comprises a layer group or a sub-layer group.

16. A computer-readable storage medium including instructions that, when executed by a processing unit, cause the processing unit to graphically organize and manage layers of a digitized map, by performing the steps of:

generating a hierarchical display of layers that includes a first layer and a second layer;

displaying a first display range defining a first set of map scales at which the first layer is displayed in the digitized map based on user input; and

displaying a second display range defining a second set of map scales at which the second layer is displayed in the digitized map based on user input.

17. The computer-readable storage medium of claim 16, further comprising the step of displaying a first graphics style and a second graphics style, wherein the first graphics style and the second graphics style represent a first map feature included in the first layer.

18. The computer-readable storage medium of claim 17, wherein the first display range includes a first subset of map scales and a second subset of map scales, and further comprising the step of displaying a first display range bar corresponding the first graphics style and spanning the first subset of map scales, and a second display range bar corresponding to the second graphics style and spanning the second subset of map scales.

19. The computer-readable storage medium of claim 16, wherein the hierarchical display of layers further includes a first node under which one or more layers of the digitized map are organized.

20. The computer-readable storage medium of claim 19, wherein the first node is a layer group or a sub-layer group.
