1. A computer-implemented method of determining geographic location data, the method comprising: responsive to user interaction with a point-of-interest-selection element of a virtual-mapping environment, receiving, by one or more computing devices and from a user device, data indicative of a request to view information associated with an unspecified point of interest within a geographic information system, the unspecified point of interest comprising a point of interest selected, from a plurality of points of interest associated with the geographic information system, subsequent to the user interaction; determining, by the one or more computing devices and based at least in part on a predefined probability scheme associated with the plurality of points of interest, a set of location constraints; identifying, by the one or more computing devices and from the plurality of points of interest, a plurality of candidate points of interest that each satisfy each constraint of the set of location constraints; selecting, by the one or more computing devices and from the plurality of candidate points of interest, the point of interest; and providing, by the one or more computing devices and to the user device for presentation within the virtual-mapping environment, data associated with the point of interest.
