Abstract

Methods and apparatus, including computer program products, for obtaining location information from a location source. A geographic reference point is determined based on accuracy of the location information. The geographic reference point is incorporated into a location result.

Claims

1. (canceled)

2. A method comprising:

receiving location information for a mobile device, the location information characterizing a location of the mobile device and a degree of error of the location of the mobile device;

determining a shape icon that characterizes the location information, wherein the shape icon circumscribes a given geographic area that includes the mobile device;

identifying one or more geographic reference points at least partially within or proximate to the given geographic area;

modifying a size of the shape icon based on an estimated degree of accuracy of the location information that is based on the identifying; and

outputting a graphical map that includes the size modified shape icon.

3. The method of claim 2, wherein the size of the size modified shape icon is inversely proportional to the estimated degree of accuracy of the location information.

4. The method of claim 2, wherein the graphical map includes an icon positioned at a center of the sized shaped icon that represents an estimated location of the mobile device.

5. The method of claim 2, wherein the one or more geographic reference points includes a road partially within the shape icon.

6. The method of claim 5, wherein the one or more geographic reference points includes an intersection of the road with another road wherein the intersection is within the shape icon.

7. The method of claim 6, wherein the modifying further comprises reducing the size of the shape icon, wherein the modified shape icon includes the intersection.

8. The method of claim 2, wherein the one or more geographic reference points includes a point of interest substantially enclosed in the shape icon.

9. The method of claim 8, wherein the modifying further comprises reducing the size of the shape icon, wherein the modified shape icon includes the point of interest.

10. The method of claim 9, wherein the point of interest is one of a landmark, a business establishment and a sports facility.

11. A location system comprising:

a memory to store machine readable instructions; and

one or more processors to access the memory and execute the machine readable instructions, the machine readable instructions comprising;

a ranker module that;

receives location information for a mobile device, wherein the location information characterizes a location of the mobile device and a degree of error of the location of the mobile device;

determines a shape icon that encloses a geographic area in which the mobile device is located;

identifies a plurality of geographic reference points for the shape icon, wherein each geographic reference point is at least partially enclosed by the shape icon or proximate to the shape icon; and

determines a score for a plurality of location results based on the identified one or more geographic reference points;

a location result selector that;

selects the location result with a highest score; and

modifies a size of the shape icon to include at least one of the plurality of geographic reference points based on the selected location result; and

a graphical user interface (GUI) that;

outputs a geographic map that includes the modified shape icon.

12. The location system of claim 11, wherein a given one of the plurality of geographic reference points is a road.

13. The location system of claim 11, wherein a given one of the plurality of geographic reference points is an intersection.

14. The location system of claim 11, wherein a given one of the plurality of geographic reference points is a civic address.

15. The location system of claim 11, wherein a given one of the plurality of geographic reference points is a point of interest.

16. The location system of claim 15, wherein the point of interest is one of a landmark, a business establishment and a sports facility.

17. The location system of claim 11, wherein the size of the modified shape icon is inversely proportional to an estimated degree of accuracy of the location information.

18. A mobile computing device comprising:

a ranking module that receives location information of the mobile computing device, wherein the location data includes accuracy data specifying a degree of error in the location data;

a shape icon determination module to generate a shape icon representing a current location of the mobile computing device that is sufficiently sized to characterize the degree of error in the location data;

wherein the ranking module further estimates a degree of accuracy of the location information based on one or more geographic reference points that are at least partially enclosed in the shape icon or are proximate to the shape icon;

an icon modification module to modify a size of the shape icon according to the degree of accuracy of the location information; and

a display to display a map that includes the size modified shape icon.

19. The mobile computing device of claim 18, wherein a given one of the plurality of geographic reference points is a road.

20. The mobile computing device of claim 18, wherein a given one of the plurality of geographic reference points is an intersection.

21. The mobile computing device of claim 18, wherein a given one of the plurality of geographic reference points is a point of interest.
