An effective presentation of navigation information for prevention of maritime disaster using AIS and 3D-GIS

We present a method for communicating navigation information that will assist operators to prevent maritime disaster. Although this topic has been extensively researched, the navigational situation of vessels has received little attention. However, such a navigational situation is essential for understanding water bodies and ensuring maritime safety. To provide effective navigation information, this study first analyzes the actual situation of vessel traffic using Automatic Identification System (AIS) data. Operators can be based on the analysis to understand the trend of navigation ships in water bodies as an important reference. From the results of the analysis, we constructed a representable navigational information system. Different information was unified on a Geographical Information System (GIS) in two-and three-dimensional formats. The system was demonstrated in a navigation simulation of a real voyage ship in Osaka Bay, Japan. The integrated information can be comprehensively and realistically interpreted by operators. Therefore, the system is expected to effectively avoid maritime disaster.
