Case study has been criticized far its lack of generalization to the larger population and lack of sampling controls. Some of shortcomings of case study methods may be overcome, by using logically consistent, rigorous, and systematic approaches. Especially, Case study method has been suggested as appropriate for researching a range of GIS implementation, utilization, and diffusion issues. This paper provides examples of how the substance of its requirements may be met in the context of GIS case study. For the successful implementation of GIS, this study suggest that the case study method in GIS appropriate to the study of casual relations in and explication of complex GIS acquisition and adoption process.

국가GIS사업 및 관련사업을 통해 다양한 지리정보가 생산되었으며, 다양한 분야의 사용자에 의해 구축 활용되는 지리정보의 특성에 따라 전국에 분포되어 관리되고 있다. 이러한 지리정보가 사장되지 않고 목적에 맞게 효율적으로 활용되기 위해서는 다양한 콘텐츠 확보가 이기종간 공동활용이 선행될 필요가 있다. 따라서 본 연구에서는 서로 다른 시스템 환경에서 지리정보를 연계하여 활용할 수 있도록 카탈로그 모듈, 브로커 모듈, 맵브라우저 모듈, 지리정보등록 모듈 등을 구현하고 Informix, Oracle, GMS, ZEUS 등 여러 가지 조합이 도출될 수 있는 시스템을 대상으로 검증실험을 하였다. 본 연구에서 도출된 모듈을 적용하여 데이터 연계의 제약조건인 DMBS, 공간DBMS 영향을 최소화함으로써 지리정보공유 활성화에 기여할 수 있다.

Korean government has promoted the projects of National Geographic Information Systems since 1995 and the utilization level of Korean National Spatial Data Infrastructure based on them has also developed. However, due to the limit to domestic market size and the legal regulation on prohibition of large sized companies' expansion into domestic spatial information markets, Korean spatial information markets are tied up in term of industrial competitiveness. To overcome those problems and evade the domestic red oceans, it is necessary to find new one in overseas' blue ocean markets. It is estimated that overseas spatial information market will be grown to 125 billion-dollar size and the annual growth rate of it will be reached to 10.5% until 2015. Thus, Asian spatial information market has a huge growth potential and it is newly rising blue oceans for Korea. Advanced countries such as Finland, Germany, Sweden, and Japan have already expanded their market size into the newly industrializing countries. To step with advanced countries, it is time to set up the new globalization strategy of Korean spatial information for expansion into newly industrializing markets. The purpose of this study is to analyze the SWOT of domestic spatial information, investigate the status on spatial information of Asian developing countries, and suggest the globalization strategy of Korean spatial information for expansion into them. The globalization strategy can be labelled as K-FBI composed of 4 domains such as Knowledge sharing platform, Frontier, Back to the basic, and Internalization. In near future, the establishment and performance of road map based on the strategy will be the milestone for Korean spatial information companies' advance into Asian developing countries.

With the rapid socioeconomic change the siting of SOC is getting more difficult due to so-called NIMBY syndrome. The objective methodology using GIS was かid as a case study to solve the complexity of the power transmission line routing. We anticipated that the new optimization of transmission routing would be the efficient and reasonable way in getting the public acceptance and settling the public complaints from transmission construction project in our country.

Informatization today has been developed in a ubiquitous environment unifying real and virtual space from digital space. To reflect on this trend, the government has promoted the u-Korea Project, which is a national strategy based on ubiquitous technology. With this national informatization policy, 'The Creation of the Infrastructure for Realization of Ubiquitous Country' for establishing a ubiquitous world is presented in the 3rd National Geographic Information System (NGIS) Master Plan, which manages national spatial information. However, we have not yet discovered distinct change for ubiquitous environments and practical technologies. The purpose of the study is to explain the current status of Ubiquitous policies and National GIS policies as a representative national information strategies directed toward the ubiquitous society by comparing Korea and Japan, and then develops improved strategies for the future.

국가GIS사업과 지방자치단체의 지리정보 구축사업을 통해 많은 양의 지리정보가 구축 및 관리되고 있으며, 지리정보시장의 수요 또한 다양화되고 있다. 지리정보가 공개되어 활용될 수 있도록 하기 위해서는 지리정보 구축 보유기관이 데이터를 적극적으로 공급하고, 이를 통해 부가가치를 창출할 수 있는 환경을 조성할 필요가 있다. 또한 지리정보를 이용할 수 있는 매개체역할을 수행하는 지리정보유통수단 및 방법은 온라인과 오프라인의 다양한 경우가 존재하므로 지리정보의 활성화를 위한 분석 및 정비가 필요하다. 따라서 본 연구에서는 법률을 근거로 하여 다양한 지리정보유통경로를 지리정보유통망을 중심으로 정비하는 방안을 제시하고, 공공부문의 역할모델을 수립하였다. 공공부문은 중앙정부와 지방자치단체 중심의 공급기관으로 구분하여 각각의 역할을 정립하였으며, 중앙정부는 홍보 유통을 위한 기반기술개발 민간과의 파트너십을 구축하고 지방자치단체는 지리정보의 공급과 갱신을 담당한다. 이를 통해 '공급-부가가치창출-유지관리'를 중심으로 중앙정부와 지방자치단체간의 상호작용을 통해 유통시장을 활성화시키고, 나아가 민간과의 협력을 통해 역할모델의 효율성을 높일 수 있는 방안을 제시하였다.

With the growing realization that the GIS data management becomes important more than ever, a great deal of the spatial data is being digitalized through various GIS projects, such as NGIS project. However, the integrated search and analysis for GIS data are highly constrained by the databases being heterogeneous and distributed among organizations. This paper is to introduce the system developed to solve the problem of interoperability in the heterogeneous and distributed databases environment. The system architecture is presented which is composed of spatial data servers, nodes, and a gateway. Also, the paper provides the implementation details of the client application to access and analyze the distributed and heterogeneous spatial data with the standardized interface. Finally, based on the technical architecture, the korea spatial data infrastructure is explained.

Currently, the necessity of inter-system integration and sharing system increases to additionally construct and efficiently utilize the geographical information data in accordance with the increase in demand for geographical information. The provision of the data within the domestic sharing system is led by the tasks within national geographical information distribution network or intra-local governmental combined system. However, any voluntary geographical information sharing cooperation body is increasingly required with the increase in necessity of administrative cooperation among neighboring metropolitan areas, including space planning and development. Accordingly, this study is aimed at looking into the constitutions and roles of cooperation bodies within metropolitan areas by the composition, distribution, update and management of data with special regard to overseas advanced cases whose sharing systems and their effects are highly evaluated, and at presenting any model of the domestic future voluntary sharing cooperation organization within metropolitan area.

It was investigated to develop the contents for the local government for the purpose of providing various and correct information. Especially it was focused to take advantage spatial information techniques, Geographic Information Systems and Remote Sensing. The research site for this study was Muan-gun located at the south-western part of Korea and this site has very high opportunities to became the central point for the economical and tourist industry. The regional information contents for Muan-gun was developed and composed of three elements； internet related, geographic information related and satellite image related elements. These contents will make a contribution for the local government to present the regional information effectively and efficiently.
