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.

Abstract: In accordance with a particular embodiment of the invention, a method for geotagging an image includes receiving an image of a real-world scene. Location information may be received corresponding to the image. The location information may identify the location of the real-world scene. The image may be synchronized with the location information corresponding to the image such that a two-dimensional point on the image corresponds to a three-dimensional location in the real world at the real-world scene. A geotag may be received. The geotag may tag the image at the image at the two-dimensional point and provide additional information concerning the real-world scene. The geotag and the three-dimensional location in the real world at the real-world scene may be stored in a geotag database.

Abstract: According to an embodiment, a mobile communication device comprises a client and a server. The client is operable to directly request information from another communication device when access to a centralized server is unavailable. The direct request bypasses the centralized server and passes through a wireless communication channel. The server is operable to directly provide information to another communication device in response to a request from the other communication device. The direct providing of information bypasses the centralized server and passes through a wireless communication channel. The mobile communication device is further operable to send requests to the centralized server when the centralized server is available.

Abstract: In accordance with a particular embodiment of the invention, a video frame comprising an image may be synchronized with a context area generated by a three-dimensional visualization tool. The context area may be selected according to location information identifying a location shown in the video frame. The video frame may be overlaid on the context area substantially at the location shown in the video frame to yield a synchronized image that may be displayed on a display.
