Real-Time Extraction of Course Track Networks in Confined Waters as Decision Support for Vessel Navigation in 3-D Nautical Chart

摘要

In an information design project at Malardalen University in Sweden a computer based 3-D nautical chart system is designed based on human factors principles of more intuitive navigation in high speeds. In this project dynamic NoGo area polygons is generated based on the draught of the individual ship and the current water level and by doing so space is divided into free and forbidden areas. Based on this an automatic wayfinding method is presented in this paper that will allow vessels to enter a goal position and have the system display a path through free water to the goal based on different parameters such as shortest route, most weather sheltered route or route most sheltered from radar detection.
