Current targeting systems such as AFATDS (Advanced Field Artillery Tactical Data System) do not have the ability to predict future locations of moving targets being tracked within the Common Operating Picture (COP). Although these systems can perform some limited terrain and mobility analysis calculations that are static in nature, they do not address the key issue of how to apply terrain and mobility factors to attack a moving target. The objective of this paper is to introduce a targeting system that investigates and demonstrates the feasibility of 4D Geographical Information System (GIS)-based tracking, prediction and visualization of ground moving targets. The system uses 3D GIS to provide a virtual 4D scenario of ground moving targets' tracking, prediction and possible bitting point within the COP. The system utilizes new advanced technology, 3D GIS and virtual reality for tracking, prediction and 4D animation simulation of moving targets. The system consists of two parts: (1) terrain-/ mobility-based tracking and prediction of ground moving targets and (2) the visualization and 4D motion simulation.
