A great variety of models including marine ecology model, water quality model, marine fluid model have been used in the marine research. The results of marine model is presented as a numerical value that is difficult for researcher to understand. In this paper, we developed a method for conversing and presenting results of marine models to visual form to improve the visualization of modelling results that is difficult to analyze and applied the method in actual practice.

본 연구의 목적은 GIS 분석기법에 의해 적조의 공간적인 분포를 분석하고 적조의 발생시기와 기상해양학적인 인자를 GIS 데이터베이스화하는 방안을 제시하는 데 있다. 1995년 남해안과 동해안에 걸쳐서 발생한 적조의 피해는 적조연구의 방향을 새롭게 바꾸었다 연안지역 소규모 만에서 국지적으로 단시간에 발생하고 소멸하던 적조의 피해가 최근에는 2년의 주기성을 가지고 유해성 적조 생물의 장기적인 번성으로 연안양식어장에 큰 피해를 발생시키고 있다. 때문에 적조발생의 해양기상학적 인자를 분석하고, 적조생물의 생물군집과 적조생물의 제거 기술 등 다양한 연구분야에서 적조 연구가 이루어지고 있다. 특히 적조의 발생시 이를 효과적으로 정확하게 적조 발생지역을 관측하기 위한 위성원격탐사를 이용하는 기술의 개발과 항공기 예찰, 선박관측 등의 조사기법이 제시되고 있다. 본 연구에서는 과거에 국내 연안에서 발생한 적조의 발생 범위와 적조 생물, 그리고 기상학적 요소 등을 하나의 지리정보시스템으로 구축하기 위해 각각의 자료를 데이터베이스화하고 빈번한 적조발생의 공간적 분포를 분석하는데 필요한 자료의 구축 방안을 제시하고자 한다.

전 세계적으로 육상자원의 고갈로 해양광물을 개발하고 이를 경제적으로 활용하려는 움직임이 점점 증가하고 있다. 이에 우리나라도 한반도 주변 해역의 해양광물자원을 확보하기 위한 탐사와 연구가 진행 중에 있다. 특히 우리나라는 삼면이 바다로 둘러싸인 지형학적 특정으로 주변국과의 자원경쟁이 불가피하여 전략적 체계적 탐사자료의 관리와 이를 활용하기 위한 방안이 필요하다. 하지만 탐사 분야가 다양하고 그에 따른 데이터가 상이하여 관리에 어려움이 있다. 현재 국내에서 해양자원에 대한 정밀탐사가 이루어지고 과학적인 정보제공이 요구됨에 따라 해양광물자원정보시스템이 구축 운영되고 있지만 몇 가지 제약점이 존재한다. 따라서 본 연구에서는 이를 보완하기 위해 특히 시추 퇴적물 탐사 분야에 있어 GIS기반의 표출 가능한 대상항목을 분류하였고, 데이터베이스 구축을 위한 모델링을 진행하였다. 이는 위치기반의 분석결과 자료를 제시할 수 있도록 하였다 본 연구는 해저 퇴적층에 분야의 과학적 정보 제공을 위한 기반을 마련하였다는데 의의가 있다. 또한, 한반도 주변에 해양광물자원의 부존 가능 지역을 파악하는데 있어 과학적 정보를 지원하고 나아가 광물자원의 매장량 추정이나 경제성 평가를 위한 정보제공의 기반이 될 것으로 사료된다. 향후 연구에서는 시추퇴적물의 깊이에 따른 데이터베이스 관리 방안과 더불어 3차원 정보 제공에 대한 연구와 모델링 결과를 통해 실제 데이터에이스 구축이 진행되어야 할 것이다.

It's important to develop Metadata standard to manage a large of marine geospatial data such as observation, ocean survey, satellite image more effectively. If we use metadata in Marine GIS we can make sense marine geospatial data, make the most of marine dataset. International standard organization's work and NGIS's standard are a good example to illustrate metadata standard's importance. But we don't have metadata standard for marine dataset, so it's difficult to search and use geospatial data In this paper, we presented common marine metadata element, and composited metadata implementation schema. Finally we constructed marine GIS metadata editing tool..

Intense competition for resources has forced many countries pay attention to their eyes to the ocean. Therefore, the disputes and the conflict over the delimitation of the EEZ and continental shelf will be sharpened. Since 1982 Law of the Sea Convention, Korea has opened the talks with Japan and China to discuss the boundary issues as the adjacent water zone is less than 400 miles between Korea and Japan and Korea and China. This study is to review the important rules and techniques for the delimitation of the maritime boundary which have defined in the Law of the Sea Convention and IHO-51 technical guide and to figure out how to build the maritime delimitation GIS DB to negotiate effectively with the neighboring countries. Definition of the base point and baseline will be the utmost important concept to delimit the ocean boundary. The policy makers and the specialists who prepare for the international negotiation meeting between the countries have to be ready to draw the maritime boundary for our best interest under the Law of the Sea Convention. The negotiation strategies and the principles can be made with the concrete and reliable database relevant to maritime boundary issues. So effective and fast strategic decision for negotiation can only be made based on maritime boundary delimitation GIS DB.

As the Internet users are growing, GIS researchers that would like to integrate various GIS informations have more interests for information searching technologies based on Web. But, even though these researches is growing a infinite possibility of utilizing the map, there are not yet providing more functionalized GIS services. This paper proposes a searching mechanism for the teacher information based on the SVG(Scalable Vector Graphics) format transformed the SHP format. We also implement the home-page link function inserted Web-connection information of the specific locations that could connect specific school web site within SVG file. We also provide the services to interpret requested query with proposed scheme.

Environmental Sensitivity Index Map(ESI Map) is useful information for efficient and prompt contolling of oil spill accident. Environmental sensitivity information relating to oil spill is very various, so efficient access and utilization for environmental sensitivity information at control field is required. In order to improve the efficiency of controlling accident at the field, it is necessary to building digital ESI Map and GIS program. In this study, GIS database was built to utilize environmental sensitivity information at Yeosu and Gyunggi bay. And the ESI Map program which is focused on the control job was developed. IMO/IPIECA's guide to make the ESI Map and Korea Coast Guard's guide to collect information for the control information map were referenced to capture environmental sensitivity data and build GIS database. The symbology of environmental sensitivity layers was defined and functions for supporting control job were implemented in ESI Map program. For the future works, the program in this study could be applied to ESI Map program for the whole coastal area of Korea and it could be the essential element technology in marine pollution control supporting system.

Recently, the interests of marine mineral resources has been increasing from the depletion of land resources around the world and many countries are involving in marine exploration work. South Korea is also currently performing exploration work to estimate the marine mineral resources around the Korean Peninsula. However, massive amounts of marine exploration data accumulated from the long-term exploration work have not been systematically managed. The data have been managed by the file based system instead of commercial database. The aim of this study is to construct GIS-based Marine Mineral Resource Information System using a spatial database for the core sediments of the marine exploration data. For constructing such DB system, GIS-based data items were classified, and a database was designed using relational database model. The database was constructed using commercial DBMS(Database Management System), Oracle. Also, necessary functions of the system were defined for the effective use of database based on users' requirement analysis. The GIS-based Marine Mineral Resource Information System has enabled to support the systematic management of the marine exploration data. Furthermore, it is expected that this spatial database will be useful in estimating the reserves of the mineral resources and provide valuable information for economic evaluation. In the future, the application of advanced techniques of spatial analysis and 3-dimensional display function will be required.

Standards are essential to facilitate the efficient use of GIS data. International Standards such as ISO TC211's 19100 series and various technical specifications from OpenGIS Consortium are some of the examples of efforts to maintain the interoperability among GIS applications. Marine GIS is no exception to this rule and in this context. developing standards for marine GIS is also in urgent needs. Using the same meaning and definition for the features commonly found in marine GIS applications is one of the ways to increase the interoperability among systems. One of the key requirements for maintaining the standard meanings for features is to build a common feature catalogue. This paper examines the concept of feature catalogue and describe the ways in which the feature catalogue can be organized. To identify the common features found in various marine GIS applications, a comprehensive search has been made to collect and analyze the features used in various applications. To maintain the interoperability with the National GIS (NGIS) system, the features used in various NGIS applications have been analyzed as well. The result of these analyses are used to create a comprehensive list of common features for marine GIS. This paper then explains the common feature catalogue for marine GIS and the provides the appropriate classification and coding systems for the common features. In addition, a registration tool for registering the common features into the standard registry has been developed in this study. This Web-based tool can be used to input features into the feature catalogue by various applications and also to maintain a standard-compliant feature catalogue by standard agencies.
