In this paper, we propose a standardization strategy for next generation electronic navigational chart which can be classified as S-100 Universal Hydrographic Data Model, to accept various requirements arising from various marine information and services as well as support e-navigation service strategies. IMO uses the next generation electronic chart standard, S-100 as Common Maritime Data Structure. It means that a common data model is needed as a key element for realization of e-Navigation and also points out that a new ICT convergence paradigm is needed not only for marine safety but also for maritime information and services. this paper considers he model-based data representation and reference model in order to understand the content and use of the S-100 standard and also considers the interconnectivity and role of the ISO/TC211 standards, which are being used as base standards for profiling to develop S-100 standard. Finally, we look at what standardization items are required for standardization of next generation electronic navigational chart supporting multi-purpose and how they are used mutually.

The revision of SOLAS, Chapter V, which entered into force on 1 July 2002, has firmly established the electronic navigational chart as part of the international maritime safety system. Its possible recognition as a paper chart equivalent confirms the considerable safety benefits provided by the official Electronic Chart Display and Information Systems (ECDIS). Elaborated by the Author IAMU Model Course on operational use of ECDIS aims to provide answers to some of the most commonly asked questions regarding various types of electronic charts (ENC, RNC, DNC) and electronic chart systems (ECDIS, RCDS, ECS). Following the earlier adoption of the International Convention STCW 78/95 and IMO model training courses, e.g. IMO Model Course on ECDIS [2], to assist in the implementation of the Convention and the associated IMO Assembly resolutions, a number of IAMU Member Universities had suggested that IAMU should develop model training courses on higher academic level to assist in achieving a more rapid transfer of information and skills regarding new developments in marine technology. The provision of model courses could help instructors improve the quality of their existing courses and enhance their effectiveness in meeting the requirements of the IAMU. In this paper the Author presents the results of two IAMU research projects sponsored by Nippon Foundation, titled 'IAMU Model Course on Training in Operational Use of ECDIS' and 'IAMU Handbook on ECDIS'.

The ENC standard, S-57 Specification was established to exchange hydrographic data between it's users such as HOs ECDIS users, etc. The digital navigation chart which is produced according to the S-57 Specification is called an ENC(Electronic Navigational Chart) and the SENC(System ENC) is a by-product of ENC suitable for computer graphics system Even though the efficient structure of SENC is a key element of measuring ECDIS performance, the amount of papers about these topics are small compared with other research fields. In this paper, the author designed an efficient spatial data structure of SENC, called Mesh This paper also includes the implementation result of the 'Mesh' which displays SENC on computer screen.

The Nautical Chart Division has the responsibility of producing charts covering the Korean Waters and its adjacent seas. In November 1994 a part of computer charting system has been introduced to the OHA and the total system of 4 workstations and 3 graphic terminals for digital compilation and ENC preparation will be delivered by the end of this year. Using this system three papaer charts are now edited as a test-base.

At these days, electronic maritime chart is in positively using various fields. But most of electronic maritime chart and topography information system is hard to using various fields despite that demand because that difficult approach from separately and specific constitution. This thesis apply to image filtering that extract requirement topography data from simplification of the whole system. And as constructing database of simple structure that getting various information from sounding depth and existing database, propose electronic maritime chart system to practicable 3D embodiment. And also propose convenience and commonplace to simple process about frequently renewal.

Electronic Navigational Chart is a sophisticated digital chart which contains navigational information such as coastline, depth of water, and nautical mark. It contains high levels of textual, spatial and graphical data, and rapidly replaces traditional paper charts. Although Electronic Navigational Chart has been successfully applied to the navigation of ships, the specific data format, S-57, requires some specialized systems. Furthermore its usage may be limited to specific domains and experts with restrictions. To overcome these limitations resulting from the specific data format, S-57, of Electronic Navigational Chart, more general data format such as XML will be preferred. If Electronic Navigational Chart is transformed into the form of XML, it can be easily accessed and exchanged on the internet. Therefore it may be used for more users and applications. In this paper, we propose an XML. Schema to equivalently represent XML for the S-57 format of Electronic Navigational Chart and develop a program translating the S-57 Electronic Navigational chart to XML document according to the proposed XML schema.

IMO adopt the revision of SOLAS convention on requirement systems for ECDIS and considered an ECDIS as the major system for E-Navigation strategy on marine transportation safety and environment protection. ENC(Electronic Navigational Chart) as the base map of ECDIS is considered as a principal information infrastructure that is essential for navigation tasks. Because ENCs are not easy to utilize for being encoded according to ISO/IEC 8211 file format, used for navigational purpose mainly, it's required to utilize in parts of Marine GIS and various marine application. In this paper, we developed KML conversion technology for ENC application. In details, we analyzed data model and encoding method of ENC, schema structure and data file of KML. Based on this results, we developed the program of KML conversion of ENCs.

The objective of this paper is to describe the result of development of collision avoidance supporting system, based on the electronic chart display and information system(ECDIS). In real ship operations, collision accidents happen frequently due to human errors such as the lax vigilance, misinterpretation of international regulations for preventing collisions at sea (COLREGs). We developed a system which will help to avoid these kind of accidents. This system can automatically recognize the risk of collisions, generate the safe alternative routes that comply with COLREGs, and then deliver the results into auto pilot. A virtual simulation assuming progressive collision situations revealed the usefulness of this system.

The -advent of electronic navigation equipment and trustworthy computer which provides people with convenience made the management system by one-man bridge operation or the least people who are needed possible through the integration of communication network with various navigation equipment and related institution. One of the most needed ultra-modem navigation device for a mate, ECDIS is a core equipment for navigation in ENS that notifies peril to mate as well as supervises all tasks in hydrographical chart, voyage planning, course monitoring and voyage recording. We should make coast and ocean voyage planning first, for the secure navigation which is considering the course circumstances and next, for the reduction of voyage dates in economical aspect. There needs a thoughtful consideration about the feature of the ship itself and the course with weather condition in taking up the course and also we have to take into accounts about appropriate distance between ships. Considering the essential conditions of ECDIS the indispensable device in the future, it was developed the basic principle for voyage planning algorithm for officer and programmed to real implementation available. In this paper including most of the requirements in ECDIS performance standard I mentioned about such a basic and a core Principle with real application by using the Visual C++ programming language. The voyage plan includes the function that indicate and modifies all the way points in the course from department port to arrival port with erasing the wrong way points. Also, it provides in a document form that shows ETA at glance in average speed sailing.
