Dynamically varied map labeling
Methods for dynamically varying label density and label placement on a map display used in mapping and/or navigation solutions. Label density and label placement on a map display are adjusted dynamically based on: a function class of a road being navigated, a function class of a road to be navigated following an upcoming maneuver, a distance to an upcoming maneuver, and/or a speed a device receiving mapping/navigation services is travelling.
1. A method for dynamically varying a density of road labels displayed on a given displayed navigational map having a given density of displayed features, comprising:
dynamically varying a density of road labels displayed on a user device as a navigational map, said density of road labels displayed being varied in number by selection for display based on:
a function class of a first road being navigated by said user device,
a function class of a next road to be navigated along a navigated route following an upcoming maneuver,
a distance to said upcoming maneuver, and
a speed said user device is travelling.
2. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1 , wherein:
said upcoming maneuver is an action for said user device to leave said first road and enter said next road along said navigated route.
3. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1 , wherein:
said road labels are displayed on said navigational map for only a predetermined number of roads preceding said upcoming maneuver.
4. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1 , wherein:
said road labels are displayed on said navigational map only for roads located within a predetermined distance of said upcoming maneuver.
5. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1 , wherein:
said user device is a vehicle navigation system.
6. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 1 , wherein:
said user device is a mobile phone.
7. A method for dynamically varying a density of road labels displayed on a given displayed navigational map having a given density of displayed features, comprising:
dynamically varying a density of road labels displayed on a user device as a navigational map, said density of road labels displayed being varied in number by selection for display based on:
a function class of a first road being navigated by said user device,
a function class of a next road to be navigated along a navigated route following an upcoming maneuver, and
a distance to said upcoming maneuver.
8. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 7 , wherein:
said upcoming maneuver is an action for said user device to leave said first road and enter said next road along said navigated route.
9. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 7 , wherein:
said road labels are displayed on said navigational map for only a predetermined number of roads preceding said upcoming maneuver.
10. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 7 , wherein:
said road labels are displayed on said navigational map only for roads located within a predetermined distance of said upcoming maneuver.
11. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 7 , wherein:
said user device is a vehicle navigation system.
12. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 7 , wherein:
said user device is a mobile phone.
13. A method for dynamically varying a density of road labels displayed on a given displayed navigational map having a given density of displayed features, comprising:
dynamically varying a density of road labels displayed on a user device as a navigational map, said density of road labels displayed being varied in number by selection for display based on:
a function class of a first road being navigated by said user device,
a function class of a next road to be navigated along a navigated route following an upcoming maneuver, and
a speed said user device is travelling.
14. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 13 , wherein:
said upcoming maneuver is an action for said user device to leave said first road and enter said next road along said navigated route.
15. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 13 , wherein:
said road labels are displayed on said navigational map for only a predetermined number of roads preceding said upcoming maneuver.
16. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 13 , wherein:
said road labels are displayed on said navigational map only for roads located within a predetermined distance of said upcoming maneuver.
17. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 13 , wherein:
said user device is a vehicle navigation system.
18. The method for dynamically varying a density of labels displayed on a given displayed navigational map having a given density of displayed features according to claim 13 , wherein:
said user device is a mobile phone.
