Abstract

A method for collecting geographic data for use with a navigation system identifies a pedestrian segment associated with a path. A text description of the pedestrian segment is collected. The text description includes one of a predetermined number of phrases and name of at least one feature visible from a location of the pedestrian segment. Data representing the pedestrian segment is stored in the geographic database.

Claims

1. A method of collecting data for a geographic database for use with a navigation system comprising:

identifying a pedestrian segment associated with a path;

collecting a text description of said pedestrian segment, wherein said text description includes one of a predetermined number of phrases and a name of at least one feature visible from a location of said segment; and

storing data in said geographic database that represent said pedestrian segment.

2. The method of claim 1 wherein said one of a predetermined number of phrases is selected from the group consisting of above, through, by, right, left, between, up, down, across, after, along, past and synonyms thereof.

3. The method of claim 1 further comprising:

determining whether said name of said visible feature provides helpful orientation for a route that exits from said pedestrian segment.

4. The method of claim 1 further comprising:

determining whether said text description is dependent upon a direction of travel along said pedestrian segment.

5. The method of claim 1 further comprising:

identifying a pair of orientation nodes as endpoints of said pedestrian segment.

6. The method of claim 5 further comprising:

collecting data indicating a respective position of said orientation nodes.

7. The method of claim 5 further comprising:

collecting data indicating a name of one of said orientation nodes, wherein said name is a name of at least one feature visible from a location of said orientation node.

8. The method of claim 7 further comprising:

determining whether said name of said orientation node provides helpful orientation for a route that passes from said orientation node onto said pedestrian segment.

9. The method of claim 5 further comprising:

determining whether a maneuver is possible at one of said orientation nodes.

10. The method of claim 1 further comprising:

collecting data indicating how the pedestrian segment connects with a road network.

11. A method of collecting data for a geographic database comprising:

collecting a name of a path in a geographic region, wherein said name is a name of at least one feature other than said path visible from a location of said path; and

storing data in said geographic database that represent said path.

12. The method of claim 11 further comprising:

associating one of a predetermined number of phrases with said name of said path, wherein said phrase and said name provide an orientation description of said path.

13. The method of claim 12 wherein said one of a predetermined number of phrases is selected from the group consisting of above, through, by, right, left, between, up, down, across, after, along, past and synonyms thereof.

14. The method of claim 11 further comprising:

determining whether said name of said path is dependent upon a direction of travel along said path.

15. The method of claim 11 further comprising:

identifying a pair of orientation nodes as endpoints of said path.

16. A geographic database that represents features in a geographic region, said geographic database comprising:

data representing a path in said geographic region, wherein said data representing said path comprising;

data representing a name of at least one feature other than said path visible from a location on said path; and

data representing one of a predetermined number of phrases associated with said name of said visible feature;

wherein said geographic database is stored on a computer readable medium.

17. The database of claim 16 wherein said one of a predetermined number of phrases is selected from the group consisting of above, through, by, right, left, between, up, down, across, after, along, past and synonyms thereof.

18. The database of claim 16 further comprising:

data indicating whether said name of said visible feature provides helpful orientation for a route that exits from said path.

19. The database of claim 16 further comprising:

data indicating whether said name is dependent upon a direction of travel along said path.

20. The database of claim 16 further comprising:

data representing a pair of orientation nodes as endpoints of said path.

21. The database of claim 20 further comprising:

data indicating a name for one of said orientation nodes, wherein said name includes at least one feature visible from a location of said orientation node.

22. The database of claim 20 further comprising:

data indicating a respective position of each of said orientation nodes.

23. The database of claim 20 further comprising:

data indicating whether a maneuver is possible at one of said orientation nodes.
