E-Navigation-supporting data management system for variant S-100-based data
Currently the International Maritime Organization (IMO) is taking the lead in developing e-navigation as an information service framework. E-navigation supports sharing, harmonization and utilization of various marine and marine-related data both shipboard and onshore. Recently, the IMO adopted the International Hydrographic Organization (IHO)s S-100 as the basis of the Common Maritime Data Structure (CMDS) of e-navigation. Thus, the various data are to be provided to e-navigation services in formats consistent with the S-100 data model. E-navigation services, in order to provide appropriate information to users, utilize and harmonize many kinds of S-100-based data such as Electronic Navigation Chart (ENC) data, bathymetric data, tidal data, meteorology data, radar-image data, and Automatic Identification System (AIS) data. In e-navigation, data management systems dealing with S-100-based data facilitate e-navigation services harmonization and utilization of the various S-100-based data. In this paper, we present an S-100 data management system that deals with various S-100-based data. We designed the system by generalization of the System ENC (SENC) kernel that manages S-101 ENC data. For development of a data management system that supports the management of various kinds of S-100-based data, we analyzed the characteristics of the S-100 data model and S-100-based data products. The S-100 data management system is designed to store S-100-based feature-oriented geographic data in the form of   pairs.
