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.

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.

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 marine environment protection. ENC(Electronic Navigational Chart) as base map of ECDIS is considered as a principal information infrastructure that is essential for navigation tasks. Though ECDIS has many advantages, it's almost impossible for the mariner to recognize the displayed information because of intense display of objects so called the clutter. In this paper, the current status and international standards on SCAMIN((Minimum Scale) attribute have been investigated. Also improvement of SCAMIN attribute of ENCs and grouping method for the sounding values was proposed.

On July 1 2012, the carriage requirement for ECDIS became mandatory in a phased-in manner. The system has since been widely used as a core bridge navigation system and as a replacement for paper charts with a back up arrangement. However operational anomalies have been found in the system internationally. IMO and IHO have recognised these anomalies and seek for solution. This study has been conducted on a survey of seafarers on the use of ECDIS with regard to anomalies identification, level of the seafarer satisfaction and requirements for further functional improvement. From the results, the ECDIS user focused requirements suggested on strengthening the level of navigational safety and efficiency. The efficiency of using main functions of ECDIS was positively evaluated. However, there were concerns regarding its operational safety.

On the advent of digital era, ECDIS has emerged as a new navigation aid that should result in significant benefits to safe navigation. More than simply a graphics display, ECDIS is a new concept navigation system capable of providing integrated information of geographical and texual data. As an official vector data for ECDIS, ENC consists of spatial and feature data to describe objects in form of points, lines and areas. IHO published International Standards for ENC, such as S-52(Specification for Chart Content and Display Aspects of ECDIS) and S-57(IHO Transfer Standard for Digital Hydrographic Data). This paper deals with the implementation of an ENC representation system which meets S-52 presentation specification and S-57 transfer standards by analyzing S-57 data structures and converting them to an appropriate internal data structures and representing them onto screen adopting S-52 presentation specification.

ENC(Electronic Navigational Chart) is an electronic chart including all kinds of information of nautical chart. Mariners have difficulty reading information because of clutter problem if display scale of ECDIS is lower than compilation scale of ENCs. IRO made SCAMIN improvement model included in S-65 Standard to settle this ENC clutter problem. This SCAMIN model includes both simple restriction that should satisfy some requirement and share geographic information, and hard restriction that should overlap with area object such as depth area, land area, dredge area. It also apply SCAMIN step of sounding value according to importance of safety navigation. In this paper, we analyzed the restrictions for SCAMIN model of S-65 Standard, developed algorithm and application to apply theses restrictions reasonably and mechanically. Also we applied this algorithm and application to Korea ENCs and evaluated the result of performance.
