To prevent accidents and take immediate actions to minimize the damages caused by such disasters, there have been several information system related to marine transportation in or near harbour areas and coastal waters. However, those systems were operated independently and not able to exchange each others important data necessary for the cooperation of the relevant authorities in case of accidents. Standards of data formats and their exchanges needed to make information systems play efficiently their roles are proposed in this paper, and the proposed method is expected to help manage the marine transportation in the waters of jurisdiction and prevent marine accidents which cause huge amounts of casualties in the shipping industries and the natural environments.
