碩士 === 國立臺灣海洋大學 === 通訊與導航工程系 === 98 === This thesis aims to extract the most taken routes and high-risk areas in Taiwan waters in order to review current routes by efficiency and safety, assist the planning of ships’ routing, service dispatch, and the tracking of ships. Various spatial analysis techniques are used to explore the database of vessel dynamic reports received from a coastal network of automatic identification system (AIS) for application testing. Track generalization is implemented based on Douglas-Peucker Algorithm. DBSCAN Algorithm was used to find out the clustering of waypoints and crossovers of vessel tracks as well as directions of tracks. Grid-based line density algorithm was used to extract the center line of the most take route. Results from these analyses form a network of sea routes around Taiwan waters. The time of ship’s arrival and the routes that ships may sail can then be estimated with the aid of such information of the route network, no matter domestic routes or international routes.
