ARGUS-IS drones, blimps, aerostats) to persistently loiter and record video of a 36 square mile area with enough detail to track individual pedestrians, vehicles or other objects of interest as long as the air asset remains circling above. Automatic object-tracking software called Persistics from the Lawrence Livermore labs allows users to auto-track every moving object within the field of regard (36 sq miles) and generate geolocation chronographs of each individual vehicle and pedestrian's movements, making them searchable via geolocation query. As ARGUS floats overhead for months at a time, it dragnet tracks every moving person and vehicle and chronographs their movements,
