Abstract: A system and methods to determine the point of origin of a moveable unit of interest, such as a car bomb in a large geographic area such as Bagdad. The system comprises of a high-flying platform such as an aircraft or satellite with the capability to obtain imagery of vehicles on the ground. The imagery is periodically transmitted to a ground unit with a receiver and indexed and stored on a storage device attached to a computer system with a display. When a terrorist event occurs on the ground such as a car bomb explosion, the system will provide a human operator the capability to track the initial location (building or home) where the vehicle departed before the event of interest occurs.
