In this study, we design a marine environmental information service system with satellite images based on satellite images to reduce the damage caused by changes in the marine environment. The system provides satellite oceanographic information such as water temperature, chlorophyll, float, etc. as hierarchical texts, which is implemented as a unit module Web service so that it can be expanded in OpenAPI environment. And stability of system plug-in portability, service hours, data extraction precision and speed are used as a basis for diagnosing service stability. By securing the function and performance of the service system implemented in this study, it can be expanded to a complex technology that can customize the users by group by adding not only general services of existing systems operated by location but also information about a specific interested areas. Especially, various other items of interest including marine environment information are developed in modules, so we expect to be able to expand and service the system by plugging into the system and to spread it in technical linkage with the related institution information system.

This study proposes a Web GUI system using MGIS-based three-dimensional data models and hydrodynamic model. The study of Web GUI (Graphic User Information) system based on the MGIS (Marine Geographic Information System) is mainly performed on effective methodologies which transform real world data to computing world data. Finally, we design a Seomjin River Estuary Web GUI system integrating above data models. It must adds more ecological information and the various service item for approach more easily in order to user.

여수권역 해양교통시설에 해양기상 수집 시스템을 구축하여, AtoN AIS를 이용하여 주변을 항해중인 선박에 해양기상 정보를 직접 제공하고, AIS 기지국을 통해 해양기상 정보를 수집 처리하여 연안여객터미널, 해경 파출장소, 유관기관을 해양기상 정보를 제공함으로서 도서민이나 해양에 종사하는 사람, 레져 인구에게 제공하는 서비스로서 해양교통시설을 활용하여 좀 더 안전한 해양 업무를 수행하고 사고로 인한 인명 및 물적, 환경적인 피해를 줄일 수 있도록 한다. 여수권역 해양교통시설에 6개 국소와 별도의 기상관측 부이를 설치하여 대기기상(풍향/풍속, 기온/습도, 기압, 시정) 과 해양기상(유향/유속, 파향/파고, 수온)을 관측 할 수 있도록 구축하였으며, 기상관측 표준화법에 맞게 센서를 검정하고, 설치하여 관측 자료의 신뢰성을 확보하였다.

Research vessels(R/Vs) used for ocean research move to the planned research area and perform ocean observations suitable for the research purpose. The five research vessels of the Korea Institute of Ocean Science & Technology(KIOST) are equipped with global positioning system(GPS), water depth, weather, sea surface layer temperature and salinity measurement equipment that can be observed at all times during cruise. An information platform is required to systematically manage and utilize the data produced through such continuous observation equipment. Therefore, the data flow was defined through a series of business analysis ranging from the research vessel operation plan to observation during the operation of the research vessel, data collection, data processing, data storage, display and service. After creating a functional design for each stage of the business process, KIOST Underway Meteorological & Oceanographic Information System(KUMOS), a Web-Geographic information system (Web-GIS) based information platform, was built. Since the data produced during the cruise of the R/Vs have characteristics of temporal and spatial variability, a quality management system was developed that considered these variabilities. For the systematic management and service of data, the KUMOS integrated Database(DB) was established, and functions such as R/V tracking, data display, search and provision were implemented. The dataset provided by KUMOS consists of cruise report, raw data, Quality Control(QC) flagged data, filtered data, cruise track line data, and data report for each cruise of the R/V. The business processing procedure and system of KUMOS for each function developed through this study are expected to serve as a benchmark for domestic ocean-related institutions and universities that have research vessels capable of continuous observations during cruise.

The Marine Environment Observation Information System supplies oceanographic information elements such as water temperature, chlorophyll, float, etc. based on satellite images to consumers. The data produced by the Korean marine environmental observatories are located in the coastal areas of Korea. But if the range is too far from a particular area of interest, due to distance or spatial constraints, the accuracy and up-to-dateness of the data can not be relied upon. Therefore, it is necessary to perform fusion and complex operation to solve the difference between the field observation and the marine satellite image. In this study, we develop a system that can process marine environmental information in the user's area of interest in the form of layered character (numeric) information considering the readability and light weight rather than the satellite image. In order to intuitively understand satellite image information, we characterize (quantify) the marine environmental information of the area of interest and we process the satellite image band values into layered characters to minimize the absolute amount of transmitted / received data. Also we study modular location-based interest information service method to be able to flexibly extend and connect interested items that diversify various observation fields as well as application technology to serve this.

Recently, there have been various researches on the cost reduction and savings during the construction activities with the development of automation and computerized information system. Considering the cost savings during the construction, the development of the geological and geotechnical information system with high practical use becomes very important since the geologic and geotechnical data are required for the design of the various structures. Currently, the geological and geotechnical data are collected and distributed as a geological/geotechnical map or engineering geology map and map with other specific purpose through geoinfo system at Korea Institute of Geoscience and Mineral Resources, Korea Mineral Resources GIS at Korea Mineral Resources Corporation, Geotechnical Information Portal System at Korea Institute of Construction Technology, Geotechnical Information System at the City of Seoul and the Ocean Data Integration Material System at Korea Hydrographic and Oceanographic Administration. Furthermore, the information on the groundwater is monitored and collected via Integrated Ground Water Information Service at Korea Water Resources Corporation and Rural Groundwater net at Korea Rural Community Corporation. Therefore, in this study, the contents of the geological and geotechnical data collected from the above mentioned government organization are compared and the DB and distribution system with higher utilization are suggested based on the comparisons with those from other countries such as United States of America, Japan and Germany.

In recent years, polar research has been focused on climate change, natural resources, and development of a new North Pole Route. Since 2010, the Korea Polar Research Institute has been collecting various in situ data from the Arctic/Antarctic oceans using ARAON, which is the first effort of Korea toward leading global polar research. As a part of these activities, a web-based GIS service was developed to collect in situ data and to standardize data formats. Visualizations of in situ measurements and thematic maps were also developed to improve both the quantitative and qualitative quality of polar ocean research, and to increase accessibility of polar oceanographic data. This system will ultimately share all of the data acquired from the Arctic/Antarctic oceans with international research groups.
