The IMO has established a regulation for the ECDIS installation on ships based on the IHO S-57 standards. The ECDIS supports sailors in achieving a safe voyage by using ENCs and monitoring the information of their ship. However, the S-57 standards were developed as edition 3.1 and prohibited revision for more than 20 years. So, the IHO developed a new standard as S-100 into the hydrography and maritime field instead of updating the S-57 to edition 4.0. In this study, the new S-100 ECDIS was developed and verified with ENCs and the digital maritime safety information by using a ship steering simulator and by conducting an on-board sea-trial test. It evaluated the impact on ship operations if the next-generation navigation support system is introduced. Based on this research, the S-100 ECDIS will generate improvements such as safe voyages by providing various of real-time safety information and up-to-date data to ship and sailors.

This paper describes a method for making 3D marine environmental database of ship handling simulator by using electronic nautical chart data. While developing simulator system, we had to digitize the nautical paper chart in order to obtain the basic data including coastline, navigational aids and so on. With the proposed method, we can get easily exact data from electronic navigational chart data, which is coded according to S-57 transfer standard of IHO and necessary to make the database of visual presentation system.

Nowadays, a precision multiple-beam epoch sounder is a depth-sounding apparatus, which is widely used especially for the mapping of bottom of the sea in the coastal area and the bed of river. However, there has been no attempt to verify the accuracy of the depth-sounding apparatus with the data obtained through the actual measurement. As a consequence, the efficient and systematic evaluation of the survey results cannot be performed. In this paper, the accuracy of the multiple beam echo sounder is analyzed by comparing the in-situ measurements and reference data. The test results show that the highest level of accuracy, indicated by IHO, can be achieved even though the magnitude of error increases with the depth of water.

Because voyages of large ship applies electronic chart, electronic chart standardization takes a peak importance in navigation safety. Currently the standard electronic chart follows the form S-57 but is currently establishing S-100 as the new Transfer Standard for Digital Hydrographic Data. S-100 was determined by IHO about Transfer Standard for Digital Hydrographic Data in 2010 years. Hence as S-100 takes place as the new standard for the safety of ocean vessel activities, the electronic chart, which was previously based on S-57, would be in avail only after it follows the new S-100 form. This paper discusses analyzations of metadata thorugh S-57 record and field, and study a system which creates S-100 Metadata.

The Iho and Hamdeok beaches, the major coastal beaches in Jeju Island, have been studied through size analysis and using an experimental extension pole and sediment trap in beach profile, in order to understand their textural characteristics, migration patterns, and seasonal change in beach geometry. The Iho beach is composed of coarse and medium sands, 590 m in total length. The foreshore slope is 12.3$^{\circ}$ in summer and 10.8$^{\circ}$ in winter, which shows more steeper in summer. The Hamdeok beach consisting mostly of shell fragments is 950 m long, $5.7{\sim}7.4^{\circ}$ steep and 97.4${\sim}$114.5 m wide, respectively. The suspended load drift concentrations in the studied beaches showed 4.5 mg/l during the period of summer and 33.2 mg/l in winter, and those of fine-grained sediments are derived mostly from the marine of northeastward direction. The typical beach transformation of the Iho beach is resulting from the construction of jetties in the west side that built up the sand inside the jetties, whereas the erosion is occurring on the east side of beach. The center and berm sides of the sand in the Hamdeok beach drift into the dune side during the period of the stormy winter season.

Recently, bemuse of extensive use of hydrographic information, interoperability of Marine Geographic products is very important for efficient use of geographic information systems. Open GIS Consortium(OGC) developed the Open Geodata Interoperability Specification(OpenGIS) to support the interoperability in the distributed environment, especially Geography Markup Language(GML) Implementation Specification. Geography Markup Language is an XML grammar written in XML Schema for the modelling, transporting, and storing of geographic information GML provides a variety of objects for describing geography including features, coordinate reference systems, geometry, topology, time, units of measure and generalized values. S-57 is currently the IHO standard for the exchange of digital hydrographic data. To date, it ms been used almost exclusively for encoding Electronic Navigational Charts(ENCs). Even though, S-57 is intended to support all types of hydrographic data. In order 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 recognized as base mop in the Marine GIS. This paper presents the process and results on development of application schema for converting ENC into GML.

This paper proposes a link model that can provide the spacial position along the surface of the earth as an information or data using ePosition ID through the Internet. Moreover, to support the information service of maritime position, it needs the ENC linked technique based on S-57 that is an IHO transfer standard for digital hydrographic data. Therefore, it designs the linked model for applying and utilizing the ePosition technology with ENC data, as well as supplementing the base technology in applying them to marine related fields. As a study method, this paper first analyses ENC data model and structure, and converses for processing of ENC file to ePosition data. Finally, it derives the interconnection method with ePosition database and shows the ePosition service application based on the linked ENC data and its validity.

국제수로기구(IHO)는 수로분야의 다양한 데이터와 서비스 표준개발을 위한 프레임워크인 S-100 표준을 개발 하였으며, 이를 기반으로 차세대 전자해도 표준을 포함하는 제품 및 서비스 표준을 개발하고 있다. S-100 기반 제품표준을 개발하기 위해서는 S-100 표준에 부합하는 Feature Catalogue(FC)가 포함되어야 하며, 이를 지원하기 위해 S-100 Feature Catalogue Builder(FCB)가 개발 되었다. S-100 FCB를 이용하여, FC제작 시 Feature를 정의하기 위해서는 Attribute를 매번 입력 하게 되는데, 공통 Attribute를 입력함에 있어서의 입력 오류와 장시간의 제작 시간이 소요된다는 문제점이 발생한다. 이러한 문제점은 현 S-100 FCB가 객체지향 개념이 고려되지 못한 것으로 판단하고, 본 연구에서는 OOP(Object-Oriented Programming) 기반의 S-100 FCB 개발 방안을 연구하였다. 이를 통해 중복되는 정보의 입력을 줄이고 제작 시간을 단축 할 수 있을 것으로 예상된다.

전자해도는 전자해도표시시스템(ECDIS)에 사용할 목적으로 선박의 항해와 관련된 모든 해도 정보를 국제수로기구(IHO)의 표준규격(S-57)에 따라 제작된 디지털해도를 말한다. 전자해도는 주로 전자해도표시시스템를 통해 이용되거나 필요한 데이터를 추출, 가공 절차를 거쳐 활용되고 있다. 본 연구에서는 전자해도 데이터 기반 웹 맵 서비스 구축 방법을 제시한다. 웹 맵 서비스는 다양한 플랫폼에서 사용할 수 있어 전자해도의 활용도를 높여주고, 맵 데이터의 업데이트를 용이하게 한다. 향후 제시된 방법을 통해 전자해도 데이터 기반의 시스템 개발에 폭넓게 활용될 것으로 예상된다.
