Abstract: One example includes a method for implementing a geographic search. The method includes receiving search data from a plurality of mobile search stations. The search data being associated with a geographic search area corresponding to a contiguous geographic area through which a respective one of the plurality of mobile search stations has traversed over time. The method also includes aggregating the geographic search area associated with the search data provided from each of the plurality of mobile search stations to generate an aggregate geographic search area. The method also includes displaying a map of a geographic region on a monitor. The method further includes superimposing a geographic location of each of the mobile search stations and the aggregate geographic search area on the map of the geographic region.
