Abstract

In accordance with a particular embodiment of the invention, a request for a geotag comprising situational information and geographic coordinates may be received from a requestor. The request may include geospatial data, such as position data and viewing angle data, that identifies a location of the requester. The position data may be latitude data, longitude data, and/or elevation data, and the viewing angle data may be azimuth data, compass direction data, and/or orientation data. The geographic coordinates of a candidate geotag may be compared to the location received in the request. If the candidate geotag is near the location received in the request, it may be sent to the requestor.

Claims

1. A method comprising:

receiving, by a geotag database comprising a plurality of predetermined geotags, a geotag request from a device associated with a requestor, wherein the plurality of predetermined geotags comprise respective situational information and geographic coordinates, the request comprising geospatial data that identifies a location and a physical orientation of the device associated with the requestor, the geospatial data comprising;

position data comprising one or more of latitude data, longitude data and elevation data; and

viewing angle data identifying the physical orientation of the device associated with the requestor, the viewing angle data comprising one or more of azimuth data, compass direction data, and orientation data;

comparing the geographic coordinates of each of the plurality of predetermined geotags to the geospatial data received in the request to determine a subset of the plurality of predetermined geotags that are near the location and within a viewing area defined by the physical orientation of the device, wherein the subset of the plurality of predetermined geotags comprises two or more geotags; and

sending the determined subset of the plurality of predetermined geotags to the device associated with the requestor in response to the geotag request.

2. The method of claim 1, further comprising:

overlaying the determined subset of the plurality of predetermined geotags on a background image comprising the location of the requestor, the determined subset of the plurality of predetermined geotags overlaid according to their respective geographic coordinates; and

displaying the background image and the determined subset of the plurality of predetermined geotags on a display of the device.

3. The method of claim 2, wherein the background image is generated by a three-dimensional visualization tool.

4. The method of claim 1, wherein the determined subset of the plurality of predetermined geotags are selected from the group of geotags consisting of social network geotags, historical geotags, identification geotags, and annotation geotags.

5. The method of claim 1, the determined subset of the plurality of predetermined geotags further comprising a respective ratings, indicating the usefulness of the respective geotags according to one or more users.

6. The method of claim 1, wherein the location of the requestor is overridden with a user viewing criterion that indicates a location of interest to the requestor.

7. The method of claim 1, wherein the request further comprises user search criteria, the user search criteria indicating a characteristic of the situational information of the subset of the plurality of predetermined geotags being requested in the geotag request, wherein the situational information is distinct from the geospatial data in the plurality of predetermined geotags.

8. The method of claim 1, further comprising:

verifying that the requestor is authorized to receive the candidate geotag, and sending the candidate geotag to the requestor only if the requestor is authorized.

9. The method of claim 1, wherein sending the candidate geotag to the requestor further comprises sending the candidate geotag from a peer of a peer-to-peer network.

10. An apparatus comprising:

a processor; and

a non-transitory computer readable media comprising logic, the logic, when executed by the processor, being configured to;

receive, by a geotag database comprising a plurality of predetermined geotags, a geotag request from a device associated with a requestor, wherein the plurality of predetermined geotags comprise respective situational information and geographic coordinates, the request comprising geospatial data that identifies a location and a physical orientation of the device associated with the requestor, the geospatial data comprising;

position data comprising one or more of latitude data, longitude data and elevation data; and

viewing angle data identifying the physical orientation of the device associated with the requestor, the viewing angle data comprising one or more of azimuth data, compass direction data, and orientation data;

compare the geographic coordinates of each of the plurality of predetermined geotags to the geospatial data received in the request to determine a subset of the plurality of predetermined geotags that are near the location and within a viewing area defined by the physical orientation of the device, wherein the subset of the plurality of predetermined geotags comprises two or more geotags; and

send the determined subset of the plurality of predetermined geotags to the device associated with the requestor in response to the geotag request.

11. The apparatus of claim 10, the logic, when executed, being further configured to:

overlay the determined subset of the plurality of predetermined geotags on a background image comprising the location of the requestor, the determined subset of the plurality of predetermined geotags overlaid according to their respective geographic coordinates; and

displaying the background image and the determined subset of the plurality of predetermined geotags on a display of the device.

12. The apparatus of claim 11, wherein the background image is generated by a three-dimensional visualization tool.

13. The apparatus of claim 10, wherein the location of the requestor is overridden with a user viewing criterion that indicates a location of interest to the requestor.

14. The apparatus of claim 10, the logic, when executed, being further configured to:

verify that the requestor is authorized to receive the candidate geotag, and send the candidate geotag to the requestor only if the requestor is authorized.

15. A device configured to:

send, to a geotag database comprising a plurality of predetermined geotags, a geotag request from a requestor, wherein the plurality of predetermined geotags comprise respective situational information and geographic coordinates, the request comprising geospatial data that identifies a location and a physical orientation of the device, the geospatial data comprising;

position data comprising one or more of latitude data, longitude data, and elevation data; and

viewing angle data identifying the physical orientation of the device associated with the requestor, the viewing angle data comprising one or more of azimuth data, compass direction data, and orientation data; and

receive in response to the geotag request a determined subset of the plurality of predetermined geotags returned in response to the request is wherein the determined subset of the plurality of predetermined geotags are each near the location and within a viewing area defined by the physical orientation of the device, wherein the subset of the plurality of predetermined geotags comprises two or more geotags.

16. The device of claim 15, further configured to:

overlay the determined subset of the plurality of predetermined geotags on a background image comprising the location of the requestor, the determined subset of the plurality of predetermined geotags overlaid according to its their respective geographic coordinates; and

displaying the background image and the determined subset of the plurality of predetermined geotags on a display of the device.

17. The device of claim 16, wherein the background image is generated by a three-dimensional visualization tool.

18. The device of claim 15, further configured to override the location of the requestor with a user viewing criterion that indicates a location of interest to the requestor.

19. The device of claim 15, wherein the request further comprises user search criteria, the user search criteria indicating a characteristic of the situational information of the subset of the plurality of predetermined geotags to be sent, wherein the situational information is distinct from the geospatial data in the plurality of predetermined geotags.
