5203 |a"Extracting valuable information from large spatio-temporal datasets requires innovative approaches that can efficiently deal with large amounts of data and, at the same time, effectively reveal the underlying structure of the data, in order to provide useful information to the decision making process. Innovative knowledge discovery techniques have been developed which use a stochastic mean-reverting modeling of the ships motion to reveal the underlying graphical structure of maritime traffic. The generated knowledge enables numerous possibilities, from graph-based multi-edge prediction to anomaly detection techniques, to ship routing optimization. Altogether, the topics covered in this report represent the theoretical framework that is required for the development of knowledge discovery techniques able to reveal the underlying graph structure of maritime traffic, which are documented in the companion report—Part II. This report—Part I—documents the formalization of the ship motion model, motivating its use over other conventional models. Procedures to estimate the process parameters are provided and its use for long-term prediction and data association isinvestigated. The main limitation of this model, its applicability to non-maneuvering targets only, is also overcome by formalizing an augmented version of the model that fits the case of a vessel navigating by waypoints. Real-world data sets are used to show the potential of the developed techniques in cases of practical relevance"--Abstract, page i.
