This paper describes a method for making 3D marine environmental database of ship handling simulator by using electronic nautical chart data. While developing simulator system, we had to digitize the nautical paper chart in order to obtain the basic data including coastline, navigational aids and so on. With the proposed method, we can get easily exact data from electronic navigational chart data, which is coded according to S-57 transfer standard of IHO and necessary to make the database of visual presentation system.
