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.

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 Singapore Strait is one of the world's busiest waterways used by international shipping Coupled with this, the Port of Singapore is the world's busiest port in terms of shipping and cargo tonnage and the second busiest container port. Navigational safety is Singapore's concern and we are convinced that the ECDIS is the key to further enhancing navigational safety in the Singapore Strait and the port waters of Singapore. We have initiated the production of Electronic Navigational Chart data and invested in infrastructural supporting facilities such as DGPS brodcast service for use with ECDIS as well as other maritime systems.

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.

As the marine transportation has increased, the safe maneuvering system has been required. SOLAS obligated regulations for carrying AIS(Automatic Identification System) onboard. This system provides navigational information including identification, classification, position, a ship's course and voyage status from own vessel to ground and other vessels. Being utilized in the most development of application service for safe maneuvering, they are to be managed systematic. In this paper, we introduce a database system to manage the voyage status and navigational information of AIS message. It is classified by static or dynamic. An electronic navigational chart display system is implemented to verify the design.

This study identified necessary navigational support services to prevent accidents through an examination and a survey on the navigation and communication systems of non-SOLAS ships. The functional and operational requirements for the identified navigational support services were discussed accordingly. Among the navigational support services proposed are an Electronic Navigational Chart (ENC) service, a route planning service, an operation monitoring service, and collision prevention support services for ships in coastal areas. To facilitate the identified navigational support services, ship navigation system, shore supporting centre and maritime communication network were discussed as a digital infrastructure. The operational methode for the digital infrastructure were discussed in the service scenarios for ships carrying dangerous cargo, large ships over 200 meters in length and high speed passenger ships over 15 knots in speed. This study will facilitate the development of policies for the improvement of ship operation management in Korean coastal waters and will contribute to improving the navigational safety of non-SOLAS ships.

This paper developed a web service system providing hydrographic information encoded by GML rules. In order to achieve the goal, every data included in an ENC, which is following the rules of the S-57 and S-52 from the IHO, is transformed into a data structure form of OLE/COM from the OOC. In the system, hydrographic information can be provided through a data provider, and then it can be encoded into GML format for web services. This paper also implemented a web client that requests hydrographic information to the server and renders result data which is a GML format following the rules of S-57.

A nautical chart is an essential material not only for the safety of navigation at sea, but also for the research and understanding of the ocean. Paper nautical harts have been used for navigational purposes for several hundreds years, but it was show that paper nautical charts have certain limitations, because the speed of ships has increased dramatically, and Global Positioning Systems (GPS) are now available at sea. Thus, the development of digital charts has been conducted by a number of countries. As a result, the International Hydrographic Organization (IHO) has developed a standard format, Special Publication No. 57 (S-57), as a guideline for the production of electronic navigational charts (ENC). Even though ENCs are a state-of-the-art navigational tool because they are produced on the basis of Geographical Information System (GIS) technology, they can be utilized for various purposes. in this paper, the usage of paper nautical charts, ENCs, and digital charts is reviewed. Also, the various application system that make use of electronic navigational harts and digital charts, as a basic geographical source of information, will be examined on the basis of GIS.
