The aim of maritime surveillance systems is to detect threats earlyenough to take appropriate actions. We present the results ofa study on maritime domain awareness performed during the fallof 2008. We analyze an identified capability gap of worldwidesurveillance in the maritime domain, and report from a userworkshop addressing the identified gap. We describe a SMARTracIn conceptsystem that integrates information from surveillance systems with background knowledgeon normal conditions to help users detect and visualize anomaliesin vessel traffic. Land-based systems that cover the coastal watersas well as airborne, space-borne and ships covering open seaare considered. Sensor data are combined with intelligence information fromship reporting systems and databases. We describe how information fusion,anomaly detection and semantic technology can be used to helpusers achieve more detailed maritime domain awareness. Human operators area vital part of this system and should be activecomponents in the fusion process. We focus on the problemof detecting anomalous behavior in ocean-going traffic, and a roomand door segmentation concept to achieve this. This requires theability to identify vessels that enter into areas covered bysensors as well as the use of information management systemsthat allow us to quickly find all relevant information.
