The high tech marine transportation infrastructure is an innovative transportation infrastructure that may be able to secure a safe transportation environment as well as efficient operation by connecting up-to-date skills including a broad range of wire and wireless communication-based information, control and electronics technologies. When integrated into the marine transportation infrastructure by the standard requirements, these standard technologies help monitor and manage navigational aids. After investigated on current status of marine transportation system, verified on integrating marine transportation systems, the standard requirements have to suggest a appropriate way of integrating marine traffic systems and proper way of using old marine traffic infrastructure.

Electronic Navigational Charts (ENCs) are digital charts which contain a great variety of data on coast and sea regions. Although they contain much information that ordinary people are interested in, there is no easy way to access because they are coded in the specialized data forma, and can be visualized by using specialized system. Therefore, supporting systems need to be developed for ordinary people to easily access ENCs. This paper proposes a framework for the ENC systems based on the Web. It relies on quite general standards such as Ceography Markup Language (GML) and Scalable Vector Graphics (SVG). In the framework, ENCs coded in S-57 format are first translated into GML to be stored in a database. Once the database is built, users can request to the database what they want. According to the user request, relevant data are retrieved, and then translated into SVG to be displayed on the Web browser. By using the framework, ordinary people may easily access coast and sea information contained in the ENCs. Furthermore, the framework may provide interoperability by virtue of XML-based standards such as GML and SVG, and efficiency by virtue of database. To validate the feasibility of proposed framework, a prototype system is developed and tested.

S-57 is currently the IHO standard for the exchange of digital hydrographic data. S-57 is intended to support all types of hydrographic data. But, it has been used almost exclusively for encoding Electronic Navigational Charts(ENCs). In onder to meet this requirement, a new standard is being developed. GML will be the core encoding rule of IHO's new standard. but there has been no study that tried to develop the GML for ENC that are reconized as base map in the Marine GIS. If ENC is transformed into the form of GML, it may be widely used for more users and applications. This paper presents the application schema for translating ENC into GML and program.

The integration of Geographic Information Systems (GIS) with the hydrodynamic model was conducted in order to revitalize the use of geographical information and to aid in the understanding of tidal circulation patterns. A 2D finite difference numerical model was used to simulate n tidal circulation in the Suyoung Bay in Busan, Korea. CIS, especially the ArcView S/W is used to input the data of the numerical model, and is also used for the visualization of model outputs on the ground in the loosely coupled method. In this paper, an electronic navigational chart (ENC), which provides more accurate information in the ocean and coastal areas than any other digital information, is used as a base map for this integration. With the help of GIS, the integration can support th understanding of oceanographic information.

선박조종시뮬레이터는 교육훈련생들에게 실제와 비슷한 환경을 제공하여 교육훈련의 효과를 높일 수 있는 장점을 가지고 있다. 그러므로 선박조종시뮬레이터에는 선박의 정확한 수학적 모델과 실제와 거의 동일한 3차원 화면이 필요하다. 이 연구에서는 전자해도와 고도데이터를 이용한 3차원 영상 제작법에 대해 고찰하고자 한다. 전자해도는 전 세계적으로 표준화 되어 있어 정확성이 가장 뛰어날 뿐만 아니라 수심, 항해물표 등 각종 데이터를 가지고 있어 보다 많은 정보를 선박조종시뮬레이터에 적용할 수 있는 장점을 가지고 있다. 그리고 고도데이터의 경우 그 정확성으로 기존의 해상환경 데이터베이스보다 훨씬 현실감을 준다. 전자해도 및 고도데이터를 이용하여 해상환경을 제작 시 정확한 많은 정보의 제공이 가능하며, 기존의 방법에 비해 제작시간을 상당히 감소시킬 수 있을 것으로 판단된다.

전자해도를 시스템에 사용하기 적합하게 변환한 구조를 SENC(System Electronic Navigational Chart)라고 한다. SENC의 구조는 전자해도 표출에 필요한 각종 공간질의, 속성질의 등의 처리, 개체 속성정보의 관리, 그리고 개체의 화면표출을 위한 정보 관리가 용이하도록 정의되어야 한다. 현재 대부분의 SENC는 파일기반으로 구현되어, SENC를 활용하는 시스템에서는 SENC의 정보들을 처리하기 위한 질의를 시스템 내에서 정의하고 처리하여야 한다. SENC를 파일이 아닌 검증된 Spatial DBMS에 구현하여 SENC가 갖추어야 할 각종 정보 관리 및 처리 기능 구현 시, 시스템의 신뢰성과 유연성에 이점을 가져올 수 있다. 본 논문에서는 기본적인 전자해도 정보 관리 및 표출에 필요한 SENC의 특성을 고려하여 Spatial DBMS를 이용하는 SENC 설계를 연구하였다.

Recently, due to the increment of national income and the living standard of citizens, the leasure business has been dramatically expanded. Among the business, inland water activities such as cruise tour or water taxi have drawn attention from the people. As more people come for a new pleasure, the frequency and the number of services continues to rise yet the safety of people values less recently. In fact, the number of relating accidents also has risen accordingly. In order to prevent such accidents in inland waters, the vessels' real time voyage data, the advanced warning system and the emergency rescuing system are required. In this paper, we have developed navigation guiding application for safety of passengers and vessels in inland waters. Navigation guiding applications not only provide Inland Electronic Navigational Chart(IENC) and vessel information but also allows communication between traffic service center and nearby vessels in case of an emergency situation. In order to implement Navigation guiding applications, developing Inland Electronic Navigational Chart was inevitable. Therefore, IENC of Han River, has developed based on measuring the water depth using multi-beam echo sounder system.

The Electronic Chart Display and Information System (ECDIS) is an integral component of ship navigation equipment, that enables mariners to view Electronic Navigational Charts (ENC). Recently, it has become possible to transport freight and energy resources via the Northern Sea Routes (NSR) as global warming has been accelerating. However, ice can impact all types of ships and the potential danger that ice poses is significant. Until now, ice, consistently proven to be one of the most dangerous threats impacting navigation in ice-covered regions, has its detailed standard in the specification of the International Hydrographic Organization (IHO) for ECDIS. The investigations described in this paper were conducted to assess the advantages and problems of the display of ice objects on ECDIS. The experiments were conducted by using the Geographic Information System (GIS) to perform ice objects with their corresponding colors and symbols. Implementation of the standardized appearance of ice objects can enable mariners to access the ice condition of seas in a short time before navigating a safe passage through potentially treacherous waters. However, remain issues that must be overcome for data on ice to be fully compatible with an ECDIS system.

Human errors have known as a majority of maritime navigational accidents such as collision and grounding. A large number of relevant research applied indirect research methods such as survey and interview. The research methods are limited to collect objective data regarding human errors due to its nature. Therefore, the purpose of this study is to improve the limitation of human error measurement of navigators by applying wearable sensors. Infrared sensors by using a 3-D printer to accommodate the special environment of a ship were developed for the study. As results, a significant reliance on the Integrated Navigation System including Electronic Chart Display and Information System (ECDIS) and Radar. The results are expected to motivate further research to investigate human errors of ship navigators to reduce the maritime navigational accidents.

최근 네트워크의 발달과 인터넷의 보편화에 따라 지리정보는 않은 분야에서 활용되고 있으며, 그 범위가 해양으로까지 넓혀지고 있다. 하지만 전자해도 등의 해양 지리정보는 선박의 항해와 같은 특수한 목적으로만 사용되어져 왔고 전용의 표시시스템을 사용해야만 하기 때문에 범용적이지 못하다는 단점을 가지고 있다. 또한 기존의 지리정보시스템들은 각각 독자적인 포맷으로 데이터를 표현하고 관리해왔기 때문에 시스템 상호간의 호환성이 떨어지고 데이터의 교환이 용이하지 않았다. 이를 극복하기 위하여 OGC에서는 지리정보를 효과적으로 표현할 수 있는 XML 기반의 GML 표준을 발표하였고, W3C에서는 벡터 그래픽의 표준인 SVG를 제안하였다. 이에 본 논문에서는 선박의 항해에만 제한적으로 사용되던 전자해도를 다양하게 활용하고 비전문가도 이용할 수 있도록 GML과 SVG에 기반한 전자해도 관리시스템을 개발하였다. 즉. GML로 표현된 전자해도를 데이터베이스화하고 사용자의 질의에 부합하는 전자해도를 검색하여 이를 SVG로 변환하여 웹 브라우저를 통하여 서비스를 제공할 수 있는 시스템을 설계하고 구현하였다.
