Abstract

The invention relates to a method for presenting points of interest (POIs) via a graphical user interface (GUI) on an apparatus. Generally, data is received via a global positioning system (GPS) and map data is received via a communications network. Next, a reference location is determined, and based on the reference location a search area is determined. Next, POIs are found within said search area, wherein said reference location is comprised within said search area, and then said POIs are organized in a multilevel hierarchy tree. Finally, the found POIs are presented on the GUI.

Claims

1. A method for presenting points of interest (POIs) via a graphical user interface (GUI) of an apparatus, said method comprising

determining a reference location,

determining a search area based on said reference location, finding POIs within said search area utilising map data, said map data comprising cache map data,

organizing said POIs in a multilevel hierarchy tree,

determining a velocity of said apparatus,

determining a cache area based on said velocity, wherein said cache area is larger than said search area,

receiving said cache map data corresponding to said cache area,

storing said cache map data, and

thereby enabling dynamic presentation of POIs present within said search area via said GUI.

2. The method according to claim 1, further comprising

receiving data via a global positioning system, and

wherein said reference location is determined using said received data.

3. The method according to claim 2, wherein points comprised within said search area constitute a convex set.

4. The method according to claim 1, wherein points comprised within said search area constitute a convex set.

5. The method according to claim 1, wherein a size of said search area is dependent of way of transportation.

6. The method according to claim 1, wherein the size of said search area is dependent of a velocity with which said apparatus is moved.

7. The method according to claim 1, wherein said step of finding POIs within said search area and said step of organizing said POIs are automatically performed after a search area change.

8. The method according to claim 1, wherein a number of levels of said multilevel level hierarchy is adjustable.

9. The method according to claim 1, wherein distances are presented in association to said POIs.

10. The method according to claim 1, wherein the size of said search area is adjustable via a slider bar in said GUI.

11. The method according to claim 1, wherein said cache map data comprises said search area.

12. A device for processing map data, comprising

a graphical user interface (GUI),

a reference location determinator adapted to determine a reference location,

a search area determinator adapted to determine a search area based on said reference location,

a velocity determinator adapted to determine a velocity of said device,

a cache area determinator adapted to determine a cache area based on said velocity, wherein said cache area is larger than said search area,

a memory adapted to store cache map data,

a point of interests (POI) determinator adapted to receive said cache map data and to determine POIs within said search area utilising map data, said map data comprising said cache map data,

a POI organizer adapted to organize said POIs in a multi-level tree hierarchy,

thereby enabling dynamic presentation of POIs present within said search area via said GUI.

13. The device according to claim 12, further comprising a receiver adapted to receive data from a global positioning system, and wherein said reference location determinator is adapted to determine said reference location based upon said received data.

14. The device according to claim 12, further comprising

a user input receiver adapted to receive user input data.

15. The device according to claim 14, wherein said user input receiver is adapted to receive a user set reference location, and said reference location determinator is configured to set said reference location as said user set reference location.

16. The device according to claim 14, wherein said user input receiver is adapted to receive search area conditions, and said search area determinator is configured to determine said search area based on said search area conditions.

17. The device according to claim 14, wherein said user input receiver is adapted to receive POI organization conditions, and said POI organizer is configured to organize said POI output data based on said POI organization conditions.

18. The device according to claim 12, wherein said search area determinator is configured to determine said search area based on said determined velocity.

19. A system for handling points of interests (POIs), said system comprising

a communications network,

a device according to claim 12 connected to said communications network, and

a number of databases containing map data connected to said communications network, wherein said databases are configured to communicate with said device via said communication networks.
