TraSeer: A visual analytics tool for vessel movements in the coastal areas

Vessel movement analysis can reveal offshore shipment activities, such as the workload of sea lines and abnormal movement paths. Discovery of vessel movement information can assist decision makers in understanding trends and identifying patterns. In our work, we propose a trajectory visual analytics tool, TraSeer, to allow users to interactively analyze vessel movements. TraSeer summarizes vessel movement trends and detects anomalous movement paths. Also, TraSeer can integrate external data sources for coastal security analysis. Finally, we provide case studies to highlight the effectiveness of TraSeer in vessel movement pattern detection and latent illegal activity discovery.
