해양기본지리정보란 해양의 여러 정보 중 기초적인 주요지리정보로서 연안 및 해양의 지형 및 경계등의 위치 및 속성에 관한 정보를 말하며, 이러한 정보는 국가기본지리정보 체계와 다양한 해양정보시스템의 기본데이터 항목으로 사용된다. 해양기본지리정보구축을 위해서는 먼저 해양기본지리정보의 항목이 선정되어야 할 것이다. 또한 해양의 측량, 관측분야에서도 급격한 기술의 발달에 따라 선정된 항목의 기존 획득자료의 활용성 여부에 대한 분석이 필요하다. 이러한 자료검증과정을 통해 기본 지리정보 자료획득에 대한 계획을 수립할 수 있을 것이며, 수립된 계획을 바탕으로 정확도 높은 자료의 획득을 위해 노력해야 한다. 다양한 방법에 의해 획득 및 구축되어진 해양기본지리정보는 해양수산관련 정보화시스템과 인터넷 등을 통해 여러 분야에서 활용 및 제공되어질 것이다. 해양기본지리정보와 나아가 해양지리정보체계의 보다 나은 구축을 위해 기존의 해양관련지리정보 및 외국사례의 분석을 통해 현재 추진중인 해양기본지리정보 구축의 방향 및 구축자료의 활용방안에 대해 간략히 언급해 보았다. 해양을 보존 관리하기 위해서는 다양한 정보를 유기적으로 구축, 관리 및 공급할 수 있는 지리정보시스템(Geographic Information System, GIS)의 중요성은 앞으로도 계속 커질 것이다.

삼면이 바다인 우리나라의 국토환경에서 해양공간정보에 대한 국민들의 수요가 증가하고 다양해짐에 따라, 육상 및 해상의 지리정보는 관련기관, 민간부분 및 일반인에게 확산하여 부가가치를 창출할 수 있는 사회간접자본으로서의 역할이 요구되고 있는 실정이다. 이에 해양수산부는 제2차 국가지리정보체계 기본계획에 입각하여, 21세기 디지털 해양건설의 초석을 마련하기 위하여 해양지리정보 사업을 추진하고 있다. 본 연구에서는 해양지리정보체계(MGIS: Marine Geographic Information System)사업의 일환으로 해양기본지리정보에 관한 연구를 통하여 해양기본지리정보의 구축 시 필요한 필수항목으로 도출되었던 항목을 기준으로 데이터 모델링 및 데이터구축지침서를 작성하였다. 또한, 향후 NGIS의 통합을 고려한 국가차원의 해양기본지리정보 구성(안)을 제시하였으며 데이터의 품질기준, 유지관리를 위한 방안을 마련하였다.

2009년에 발사 예정인 통신해양기상위성은 우리나라 최초의 정지궤도 위성이며 해양기상관측위성이다. 해색관측에 있어서 정지제도 상에서 한반도와 주변해역을 관측하는 것은 시-공간해상력에서 향상된 해색위성자료를 제공해 줄 것이다. 이러한 정지궤도 해색위성 자료의 해양지리정보 활용은 적용의 범위와 GOCI 자료가 제공하는 정보의 해석적 내용에 있어서 기존의 극궤도 위성자료를 활용하는 것과는 다른 차원의 자료 구축 능력을 제시할 수 있다. 본 연구에서는 정지궤도 해색위성에 탑재된 GOCI로부터 획득되는 영상정보를 통해 해양지리정보에 적용 가능한 분야를 해석하고 이를 적용하는 방안에 대해 제시하였다. 해양지리정보의 다양한 구축 자료와 개발된 해양공간정보시스템은 향후 해양위성자료의 실시간 분석결과를 반영하여 자료의 갱신과 추출 정보의 신속한 서비스를 구현할 수 있을 것으로 판단된다. 이러한 정보서비스의 효과는 지구온난화에 따른 기후변화와 기상이변 등의 해양기상재해에 보다 신속하게 대처하는 재해정보시스템의 구현에 기여할 것으로 판단된다.

For a long time, the ocean was regarded as unknown area ruled by god, consequently, not so much things were developed in scientific methods and activities. Despite a rapid development of geographic information systems(GIS) marine and ocean fields still remained in the scope of traditional tools and intuitive experiences by the late of 1990. However, land based concepts and technology models require additional customization to apply GIS effectively in marine domains, which are resulted from her dynamic, complex and seamless massive nature. This paper gives a brief review of marine spatial data characteristics and also presents strategic approaches to meet the unique marine GIS requirements.

MGF(Marine Geographical Framework) data are the essential data sets concerning graphical and attribute information on coast and ocean among various marine-related data, which consist of framework data of the National Spatial Data Infrastructure(NSDI). This study did research and analyzed the development of current data, the situation of its usage, related technical environment and case study of foreign countries through the survey on the users and experts. Then the item of marine geographical framework data was selected in accordance with the measures for usage and management of possible MGF data. A map was pilot producted based on selected items and MGF data was presented through making up some problems shown ill the process. The importance of GIS will be growing continuously which can develop, deal with and provide the various data to efficiently manage coast and ocean. Accordingly, the MGF data will be applied to various areas such as Internet or raw data for marine information system.

Although features, core element of marine GIS in many application, are same things users have difficulty in using them on account of varying according to method of classification. Accordingly feature cataloguing in accordance with the standard is the trend of the modem world. In this article we have became familiar with ISO 19110 - Methodology for Feature Cataloguing, we was able to discuss element and definition of features for the purpose of Marine GIS's activation. Through the result of study, we presented the methodology of Marine GIS feature cataloguing.

In order to improve user accessibility and interactivity, system scalability, service speed, and a non-standard internet web environment, we developed a Web-based geovisualization system of oceanographic information using HTML5 and dynamic particles. In particular, oceanographic and meteorological data generated from a satellite remote sensing and radar measurement and a 3-dimensioanl numerical model, has the characteristics of a heterogeneous large-capacity multi-dimensional continuous spatial and temporal variability, based on geographic information. Considering those attributes, we applied dynamic particles represent the spatial and temporal variations of vector type oceanographic data. HTML5, WebGL, Canvas, D3, and Leaflet map libraries were also applied to handle various multimedia data, graphics, map services, and location-based service as well as to implement multidimensional spatial and statistical analyses such as a UV chart.

To monitor and predict the change of coastal environment according to the construction of Saemangeum sea dyke and the development of land reclamation, we have done real-time and periodic ocean observation and numerical simulation since 2002. Saemangeum coastal environmental data can be largely classified to marine meteorology, ocean physics and circulation, water quality, marine geology and marine ecosystem and each part of data has been generated continuously and accumulated over about 10 years. The collected coastal environmental data are huge amounts of heterogeneous dataset and have some characteristics of multi-dimension, multivariate and spatio-temporal distribution. Thus the implementation of information system possible to data collection, processing, management and service is necessary. In this study, through the implementation of Saemangeum coastal environmental information system using geographic information system, it enables the integral data collection and management and the data querying and analysis of enormous and high-complexity data through the design of intuitive and effective web user interface and scientific data visualization using statistical graphs and thematic cartography. Furthermore, through the quantitative analysis of trend changed over long-term by the geo-spatial analysis with geo- processing, it's being used as a tool for provide a scientific basis for sustainable development and decision support in Saemangeum coast. Moreover, for the effective web-based information service, multi-level map cache, multi-layer architecture and geospatial database were implemented together.

At a turning point of new paradigm, each countries in the world are try to search solutions to a current problems of the times in maritime than land. In special, as a maritime power that KOREA is surrounded by the sea on three sides, our country place more weight on maritime. To accomplish a powerful maritime power, it is necessary to create a digital marine spatial on the basis of Marine and Coastal GIS. This planning is establishing that our country, to construct a systematic, efficient Marine and Coastal GIS Infrastructures, is to analyze the present state of internal & external, law and planning related in Marine and Coastal GIS, and establish vision, mission, core values, goals, strategies by setting a basic concept of Marine GIS

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.
