Abstract

Systems and methods for presenting information in response to a user interaction with a geographic image at a point of query in a geographic information system are provided. A user can request information at point of query in the geographic image. Responsive to the user request, the geographic information system can search for and obtain information associated with the request. As part of the logic used to return information responsive to a request at a point of query, a zone of influence can be defined for one or more features depicted in the image. The zone of influence can be defined by a pixel threshold in a pixel space associated with the geographic image. The pixel threshold can be constant across a plurality of zoom levels of the geographic image.

Claims

1. A computer-implemented method of presenting information in conjunction with a point of query, comprising:

receiving, by one or more computing devices, a request for information at a point of query, the point of query associated with a geographic location;

responsive to the request, obtaining, by the one or more computing devices, information associated with a feature located proximate to the point of query, the feature having a zone of influence encompassing the point of query, the zone of influence defining a region in a geographic image depicting the feature; and

providing for the display, by the one or more computing devices, the information associated with the feature in the user interface;

wherein the zone of influence of the feature is defined by a pixel threshold in a pixel space associated with the geographic image, the pixel threshold being defined irrespective of the scale of the geographic image.

2. The computer-implemented method of claim 1, wherein the pixel threshold is constant across a plurality of zoom levels of the geographic image.

3. The computer-implemented method of claim 1, wherein obtaining, by the one or more computing devices, information associated with a feature located proximate to the point of query comprises prioritizing information associated with the feature relative to information associated with a different feature, the different feature having a zone of influence that does not encompass the point of query.

4. The computer-implemented method of claim 1, wherein the method comprises presenting the geographic image in the user interface.

5. The computer-implemented method of claim 4, wherein the point of query comprises a user interaction at a point depicted in the geographic image.

6. The computer-implemented method of claim 4, wherein the geographic image is presented at a first zoom level.

7. The computer-implemented method of claim 6, wherein the method further comprises presenting the geographic image at a second zoom level, the zone of influence of the feature having a constant pixel threshold for the first zoom level and the second zoom level.

8. The computer-implemented method of claim 1, wherein the point of query is associated with a mobile device location.

9. The computer-implemented method of claim 8, wherein the mobile device location is associated with a level of uncertainty.

10. The computer-implemented method of claim 9, wherein the geographic image has a zoom level determined based at least in part on the level of uncertainty.

11. The computer-implemented method of claim 10, wherein the zone of influence has a constant pixel threshold across a plurality of different zoom levels of the geographic image, each of the plurality of different zoom levels of the geographic image corresponding to different levels of uncertainty of the mobile device location.

16. The computing system of claim 11, wherein the point of query is associated with a mobile device location.

17. The computing system of claim 16, wherein the geographic image has a zoom level determined based at least in part on a level of uncertainty associated with the mobile device location.

12. A computing system, comprising:

one or more processors; and

one or more computer-readable media, the one or more computer-readable media storing computer-readable instructions that when executed by the one or more computer-readable media cause the one or more processors to perform operations, the operations comprising;

receiving a request for information at a point of query, the point of query associated with a geographic location;

responsive to the request, obtaining information associated with a feature located proximate to the point of query, the feature having a zone of influence encompassing the point of query, the zone of influence defining a region in a geographic image depicting the feature; and

providing for display the information associated with the feature in the user interface;

wherein the zone of influence of the feature is defined by a pixel threshold in a pixel space associated with the geographic image, the pixel threshold being defined irrespective of the scale of the geographic image.

13. The computing system of claim 12, wherein the pixel threshold is constant across a plurality of zoom levels of the geographic image.

14. The computing system of claim 12, wherein the method comprises presenting the geographic image in the user interface.

15. The computing system of claim 14, wherein the point of query comprises a user interaction at a point depicted in the geographic image.

18. One or more tangible non-transitory computer-readable media storing computer readable instructions that when executed by one or more processors cause the one or more processors to perform operations, the operations comprising:

providing for display a geographic image at a first zoom level in a user interface displayed on a display device, the geographic image depicting at least one feature at the first zoom level;

providing for display the geographic image at a second zoom level in the user interface, the geographic image depicting the at least one feature at the second zoom level;

wherein the at least one feature is associated with a zone of influence defining a region in the geographic image associated with the feature, the zone of influence of the at least one feature defined by a constant pixel threshold across the first zoom level and the second zoom level.

19. The one or more tangible non-transitory computer-readable media of claim 18, wherein upon receiving a user interaction at a point of query within the zone of influence, the operations comprise providing for display information associated with the feature in the user interface.

20. The one or more tangible non-transitory computer-readable media of claim 19, wherein the operations comprise obtaining the information associated with the feature based at least in part on prioritizing the information associated with the feature relative to information associated with a different feature, the different feature having a zone of influence that does not encompass the point of query.
