1996년에 3판이 발행된 S-57 표준은 디지틀 수로데이터의 국제적인 교환 표준형식이며 ENC는 S-57을 기본형식으로 하고 특정 상품을 위한 생산품 규약에 의해 만들어진 것이다. ECDIS에 사용되기 위해 만들어진 디지틀 해도 데이터 상품이지만 앞으로 예상되는 ENC 데이터의 일반적 목적을 갖고 있는 사용자들이 모두 S-57과 ENC 생산품 규약을 이해하고 데이터를 읽기 위해 시간과 노력을 투자하는 것은 무척 소비적인 일이 될 것이다. 즉 사용자의 요구는 데이터의 형식이 아니라 데이터의 사용에 집중된다. 그러므로 사용자가 데이터의 내부형식을 알지 못하더라도 사용하고자 하는 의도에 맞게 데이터의 내용을 보여주고 필요한 형식으로 재가공하여 사용할 수 있도록 데이터를 제공하는 프로그램이 필요하며 이는 ENC의 보급 및 활용도를 높이는데 매우 중요하다고 할 수 있다. 본 논문에서는 Data Loader 개발의 기초 단계로 ENC 데이터를 텍스트 형태로 전환하여 ENC에 담긴 내용을 파악할 수 있도록 하는 ENC Data Loader의 기능과 프로그램 개발과정에 대하여 기술하고 텍스트가 아닌 그림으로 보여주며 일반적인 데이터 교환형식으로 변환하는 둥의 새로운 모듈 개발과정을 설명한다. 이를 위해 ENC 데이터의 형식과 내용을 분석하고 GIS 측면에서의 데이터 해석을 시도한다. 또한 이러한 프로그램을 이용한 향후 ENC 데이터의 활용방안에 대하여 기술한다.

항해 안전을 위한 최첨단 장비의 개발은 항해업무의 감소와 항해안전에 크게 기여하고 있다. 이러한 장비 중 하나인 ECDIS(Electronic Chart Display & Information System)의 운용을 위해 개발된 ENC는 현재 전 세계적으로 제작되고 있으며 각국의 HO(Hydrographic Office)가 자국의 공인 ENC를 제작하여 종이해도의 경우와 같이 사용자에게 배포할 예정이다. ENC는 해도에 관련된 지형정보와 해당 속성정보를 포함하고 있기 때문에 항해 뿐만 아니라 기타 응용분야에도 사용이 가능하다. 이러한 필요성에 대처하기 위해 ENC 데이터를 분석하고 근간이 되는 S-57데이터의 구조, 또한 캡슐화에 사용된 ISO/IEC 8211에 관하여 소개한다. 또한 결론부에 항해 및 기타 응용분야에서의 ENC데이터 사용 가능성을 검토한다.

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.

Currently, ECDIS and GPS plotters are much used as equipment providing operators with route information, but they do not have any function of automatic route creation and route explanation, so available for only experienced operators. Especially, the present situation is tint no study is made of the automatic route creation and route explanation using ENC for ECDIS, substitution system of paper chart. ENC is the electronic navigation chart that is produced using S-52, S-57 standard format required by IHQ. In this paper, an Vessel Operator Support System(VOSS) is proposed to generate an optimal route where ENC and GPS data is fusioned induding the wind direction and speed of an anemometer and tide data. The proposed system was testified by a simulation, and its effectiveness was verified.

현재 선박에서 항해사에게 항로정보를 제공하는 장비는 ECDIS와 GPS 플로터가 많이 사용되고 있으나 자동항로생성 및 항로설명기능이 없어 숙련된. 항해사만 사용할 구 있는 문제가 있으며, 특히 종이해도의 대체 시스템인 ECDIS에 사용되는 ENC를 이용한 자동항로생성 및 항로 설명에 관한 연구는 없는 실정이다. ENC는 IHO에서 정의한 S-52, S-57 표준포멧을 기반으로 제작된다. 본 논문에서는 ENC의 해도데이터와 GPS의 위치데이터, Anemometer의 풍향$\cdot$풍속데이터, 조류데이터를 이용하여 현 위치에서 목적지까지의 최적항로를 설계하여 안내해주는 통합형 항해가이딩시스템(INGS)을 구축하여 그 유효성을 확인하였다.

Especially, the present situation is that no study is made of the automatic route creation and route explanation using ENC for ECDIS, substitution system of paper chart. ENC is the electronic navigation chart that is produced using S-52, 5-57 standard format required by IHO. In this paper, an Navigation Guiding System(NGS) is proposed to generate an optimal route where ENC and GPS data is fusioned including the wind direction and speed of an anemometer. The proposed system was testified by a simulation, and its effectiveness was verified.

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 satellite navigation system is widely used for identifying a user's position regardless of weather or geographic conditions and also make effect on new technology of marine LBS(Location Based Service). which has the technology of geographic information such as the ENC. Generally, there are conceivable systems of marine LBS such as ECDIS, or ECS that use the ENC itself with powerful processor in installed type on ships bridge. Since the ENC is relatively heavy structure with dummy format for data transfer between different systems, we should reduce the ENC to small and compact size in order to use it in mobile platform. In this paper, we assumed that the mobile system like PDA, or Webpad can be used for small navigation or information system in marine field. We considered the reduction of the ENC size to make them fit well to small capability of mobile platform. However, the ENC should be updated periodically by update profile data produced by HO. If we would reduce the ENC without a consideration of update, we could not get newly updated data furthermore. As summary, we studied considerations for ENC reduction with update capability. It will make the ENC be useful in many low performance platforms for various applications.
