THE VESSEL ROUTE PATTERN EXTRACTION AND ANOMALY DETECTION FROM AIS DATA

Gözde BOZTEPE KARATAŞ

Abstract:

The need for a variety of auxiliary analytical tools to enhance marine safety and marine status awareness has been expressed by various platforms. There are lots of data
sources breaking out while the ship is on cruising. Automatic Identification System
(AIS) device that is widely used in vessels, is one of them. It broadcasts information such as type of ship, identity number, state, destination, estimated time of arrival
(ETA), location, speed, direction, cargo. In this study, to aid operators while sailing, the trajectory extraction and anomaly detection tool have been developed. The
AIS messages are used to improve a system for safe navigation. Three different approaches are applied for the prediction of the vessel trajectories. Later, movements
that have not matched the route patterns and unusual stop anomalies have been examined.
