1. A computer system having a processor and a memory coupled to the processor, the memory containing instructions, when executed by the processor, causing the processor to perform a method comprising: determining a plurality of physical areas in space covered by one or more cameras carried by one or more users, each of the physical areas defined by an approximate point of origin and an approximate direction; overlapping the determined plurality of physical areas relative to one another in a geographic representation, the overlapped physical areas having a density of coverage; identifying an area of interest based on the density of coverage of the overlapped physical areas; and associating one of the users with the area of interest if the camera carried by the user has a physical area that at least partially overlaps the area of interest.
