Abstract
Electronic Navigational Charts (ENC’s) are digital charts encoded in S-57 format, which contain navigational informations such as coastlines, depth areas, and nautical marks. Although they have been successfully used for safe navigation of ships, they have limited usages and applications because of their specialized data format and access systems. To cope with such drawbacks, S-57 ENC’s need to be transformed into more generalized format such as Geography Markup Language (GML). The transformed GML ENC’s can be kept in a database for efficiency, and can be accessed through Internet for usability. This thesis proposes a new method for transforming the S-57 ENC’s into GML for and managing the XML database on GML. S-57 ENC’s are first translated into GML data, and then stored in a XML database. On the database, users can query for their needs. To validate the feasibility of the proposed method, a prototype system is developed, and then several test runs are conducted. The system can provide users with easy access to marine informations contained in ENC’s. It also provides accessibility and efficiency, by virtue of GML and database, respectively.
