Comparison of the Applied of Car Navigation System and Developed Marine Navigational System

A watch officer in sailing a ship uses many kinds of navigational information to prevent marine disasters. Especially in coastal sea area such as narrow bay or port, many ships crowds and marine disasters tend to occur more often. In these regions, effective presentation of variety navigational information is very important. A car navigation is very effective in road traffic; however, it is almost never used in sea traffic. The authors' objective in this paper is to apply a car navigation to ship sailing. Also, a marine navigation system proposed by them was compared with a car navigation system. In this study, the authors explored some ways of utilizing car navigation technology for the sea. To improve navigational security and safety, they investigated whether car navigation systems could be applied to marine traffic. The applicability was evaluated through several comparisons of our navigation assistance device using GIS.
