Geodetic surveying using precise GPS equipment are used without analysis with a statistical verification of GPS observed value and it was preformed by necessity to integration projection of digital topographic map and nautical Chart for integration geographic information system construction. The purpose of this study proposes method that improve accuracy of GPS observed value and direction that integrally manage digital topographic map and electronic nautical chart in analyzing the boundary line error between digital topographic map and nautical Chart. For improvement of the precision of GPS observed value, the author studied precision-analysis of GPS observed value by geometric strength and variance factor in 3 control points used in GPS network adjustment. This study compare the whole boundary point error When producing EDM measurement using this GPS observation results and setting digital topographic map and nautical chart by these boundary.

Many countries are producing the ENC(Electronic Navigational Chart)for their own waters and developing the electronic navigational equipment such as ECS, and ECDIS. Though ECDIS has many advantages, it is almost impossible for the mariner to recognize the displayed information because of intense display of objects so called as the clutter. In this paper, the problem of scale factor has been investigated and now methods, variable factor system, to assign the scale factor were proposed.

우리나라의 연간 물동량 중 선박에 의한 물동량이 약 90% 이상을 차지하고 있으나 이러한 선박에 의한 막대한 물동량을 효율적으로 처리하기 위한 해양물류시스템의 구축이 미진한 상태이다. 이를 위해 국가에서는 항만의 물류시설을 확충하는 등 물리적인 대안을 가지고 시설 부족에 대한 대비를 하고 있다. 그러나 해양물류시스템에 있어서 또 다른 중요한 문제점은 각 선사별, 물류회사별로 공통업무에 대해 각기 다른 시스템과 데이터베이스를 운영함에 있다는 것이다. 이와 같은 독립적 시스템의 운영은 동일 업무에 대한 중복투자를 유발하게 되어 많은 시간 및 비용을 소요하게 되며, 원활한 정보교환에 걸림돌이 되고 있다. 따라서 본 연구에서는 국제적인 표준안이 마련되어 있는 전자해도(ENC, Electronic Nautical Chart)를 이용하여 클라이언트-서버 방식의 관리자용 선박 및 화물 위치검색시스템을 구현하였으며, 추후 다른 항만에서도 사용이 가능하여 독립적 시스템의 운영으로 인한 중복투자를 방지 할 수 있는 방안을 제시하였다. 아울러 전자해도의 새로운 활용 방안이 없는 현 시점에서 전자해도를 선박 및 화물 위치검색시스템의 위치 표시를 위한 도형 데이터베이스로 사용하여 전자해도 본연의 목적 이외에도 활용될 수 있는 실례를 제시함으로써 전자해도의 새로운 활용 가능성을 제시하였다.

The Korean government has designated speed-limit zones and speed limits in 19 ports and 3 routes to ensure safe navigation and transportation. However, the speed limit differs from port to port, no practical means of management exist. This often leads to violation of the speed limit. Additionally, ship collisions due to human error continue to occur. First, the study analyzed marine accidents that occurred at trade ports and fairways. The result of the analysis revealed the occurrence of 1344 accidents (average 269 cases per year) from 2014 to 2018. Five hundred sixty three accidents involved fishing boats, whereas, merchant vessels were involved in 508 cases. Second, the efficacy of the application of voice and message warnings to GPS plotters and electronic chart display and information system (ECDIS) was reviewed, and these were proposed as measures to inform vessel operators of the hazards of speed limit violation. Third, experts' opinions from relevant agencies and navigation system manufacturers were consulted and it was found that the proposed warning function was technically implementable. The findings are expected to help reduce human error among ship operators and establish a Korean e-navigation system.

Maritime transportation engineering is a technical field that observes the flow of vessel's traffic in accurate and describes the feature of ship's movement statistically, then contributes to the improvement of traffic flow and the safety of traffic. The flow of marine traffic can be controlled by carrying out assessment and analysis of vessel's traffic. It can realize the safety of marine traffic by accurate research and analysis of vessel's traffic, understanding its flow and analysis data of vessel traffic. This study the analysis system of marine traffic connected with Radar, AIS based on ENC(Electronic Navigational Chart). The marine traffic analysis system contributes to safety of marine traffic through the design of marine traffic route, harbour facilities and improvement of vessel's traffic flow.

Official Development Assistance(ODA) Project is initiated to assist a developing country economically and to promote its welfare. Support on training and information system development are the primary elements in the maritime safety field. The maritime safety information system(MSIS) of ODA projects deals with maritime safety information of developing nations and ensures an inter-operability between other systems. Therefore, it is required to develop MSIS based on the Universal Hydrographic Data Model(UHDM) of International Hydrographic Organization(IHO). In this paper, we have analyzed the current status and operational process of UHDM established by IHO. Oil spill response system was selected as an example of MSIS project and, also, considered the application results to the maritime safety field of UHDM.

According as marine leisure industry has developed and the demand of leisure culture has increased rapidly, a desire about service which supply marine safety and connect marine information is enlarging. We wish tc develop contents of download form that supply geographic information of Electronic Navigational Chart(ENC) in the marine that is digitalized to carrying along terminal of WIPI base and various informations for marine leisure. For this, DB that offer ENC and additional information should be constructed. Also, we need server (CPS; Contents provider Server) that offer required contents. In this paper, we design web retrieval component which store request information to database. When consumer required necessary information through personal mobile device, CPS can inform that. So, we wish to develop web retrieval agent component that parse informations in various World Wide Webs, and store to database.

The Korean government is developing a systematic plan of integrated coastal management for effective conservation, utilization, and development of coastal areas. For this plan, integrated maps of land maps and nautical charts are indispensable. However, these maps are not made, nor studied yet in terms of integration, although digital maps(DM) on land and electronic nautical charts(ENC) have been recently developed by Korean Geography Institute and National Marine Investigation Institute, respectively. In this study, as preliminary studies to make eventual integrated maps, the concept of coastal areas are defined, specifically, coastal lines from DM and ENC are matched against each other. Issues on map production procedures, coordinate systems, and map projections, are carefully considered. A test coastal area located in Seo-Gu, Pusan, over 14 km of coastal lines is selected for the edge matching of coastal lines. RMS differences are 13.83 m and 4.37 m over man-made coastal lines and natural coast lines, respectively, which are quite larger considering a scale difference and other factors. However, no systematic differences are found.
