For the ubiquitous web environment internet, as an one of the R&D projects by Korean Land Spatialization Group, the project for platform technologies was initiated to provide customized land information and geospatial service. The platform technologies can be categorized for streaming, mashup and geosearch. More specifically, the 2D/3D hybrid streaming engine, mashup engine for u-GIS service and next generation search engine for land information have been developed. In this context, the patent analyses are required to propose the strategies for efficient development and use of these technologies. This study searches the related patents in Korea, US and EU, analyzes the trend of them for customized spatial information technologies, and finally proposes proper strategies.

Various basic information is required to scientifically and rationally utilize and manage national territory. For this, a variety of informatization projects have on developed from public sectors. However, there are a lot of problems including weak linkage between individual information systems and databases and lack of the coordinating function in promoting national territorial informatization projects. This study aims to provide policy alternatives on the integration and linkage of basic information within national territorial planning system. These results will be applied to the planned utilization and environmental friendly management of national territory.

The u-GIS national land information providing technology is the technology which maximizes the application of u- GIS data through the national land information platform technique of the next generation web and provides a user with the on-demand national land information in the ubiquitous environment. Recently, as the environment emphasizing the web as a platform 'Web 2.0' emerges, the where 2.0 which is paradigm is diffused in the spatial information area. And the Geo-spatial Web technology develops in a center. Moreover, it is changed to the open platform of the user participation trend. And the consumer of the geo-spatial information is changed to the end-user center from the public institution. The geo-spatial technique is technologically faced with the new challenge. In this paper, we analyze the technical tendency about a paradigm, And we present the u-GIS national land information platform technique, the u-GIS national land information visualization technology, the u-GIS national land information GeoDRM integrative technique, and the u-GIS national land information mobile application technology as the essential elemental technology for overcoming this.

For desirable ubiquitous web environments, one of the R&D projects by Korean Land Spatialization Group, has been done to develop a geospatial platform for custom ized land information and geospatial services. To make a better judgement for the investment in the project, analyses for evaluating value of the platform technology and others are done to propose better strategies for the future project management and commercialization of the platform technology. Wiith review of theories and evaluation methods for the technological values, this study suggests 3 evaluating methods: cost approach methods, market approach methods, and income approach methods with focusing on the customized geospatial information platform technology. Results of the evaluation are as follows: the value(over 3,600 million won) estimated by using cost approach methods is larger than the value(over 2,200 million won) using income approach method. Based on evaluation time and methods, the estimated value of geospatial platform technology can be different. This study is performed in relatively early stage of technology developments and results of it will be a reference for commercialization of customized geospatial information platform technology.

인류문명사는 미지의 새로운 세계를 개척하고 신기술과 지식을 창조하기 위한 끊임없는 도전의 역사이다. 그 과정에서 남보다 먼저 신대륙을 선점하고 선진기술을 개발한 집단이 세계를 재패해 왔다. 오늘날 지구상에는 탐험할 만한 미지의 대륙이 거의 사라졌다. 하지만 지난 10여년 동안 인류는 컴퓨터와 인터넷에 사이버공간이라는 ‘보이지 않는 대륙(Invisible Continent)’을 창조하고, 그 곳에 인류가 그 동안 창조한 모든 정보와 지식 그리고 기술과 제품들을 차곡차곡 쌓아가고 있다. 특히 최근에는 정보기술의 급속한 발달에 힘입어, 정보기술 선진국들과 일부 다국적 정보통신 기업들은 한 단계 더 발전하여 현실공간과 사이버공간을 융합한 ‘사이버국토’ 또는 ‘사이버도시’, 나아가 ‘사이버지구촌’ 건설에 투자를 확대하고 있다. 사이버국토는 현실국토공간을 사이버공간에 그대로 반영하여 최적융합함으로써, 사이버공간에서 시간·공간·인간 즉 삼간(삼간)을 통합하고, 기존의 모든 디지털활동을 수용하며, 시뮬레이션이 가능한 제2의 국토건설을 지향하고 있다. 또한 사이버국토 건설의 경험과 기술을 바탕으로 향후 전개될 사이버지구촌시대를 선도하고, 건설 과정에서 얻게되는 통합정보기술의 선점을 통해 세계 정상의 정보기술 강국으로 도약하는데 목표를 두고 있다. 이러한 사이버국토를 구축하기 위해서는 관련법률과 제도를 정비하고, 관련기술과 산업을 국가발전의 핵심 엔진으로 육성하며, 대국민 흥보와 관계자 교육을 강화하는 전략이 필요하다.

Recently many of earlier GIS services are changing to the form of user-participated dynamic geoweb service like many new impressive web 2.0 services substitute for earlier old-fashioned web 1.0 services. Many relevant technologies are necessary to be developed so as to integrate a number of geospatial data and functions all around into the useful geoweb services. It is also necessary to make the integration easy and to cope with the rapid changes in geoweb environment. In this study, the trend of relevant geoweb technologies were reviewed before, and the development of open geospatial service platform were carried out. As a result, open 2D/3D map service engine, user-participated mashup engine, Open API search engine and so on were im plemented as the core components of that platform. The platform will be able to be used as the common platform among a number of applications in the fields such as public/private GIS integration, u-city projects and GIS/LBS services etc.

In Web2.0 environment, with advanced platform technologies, global vendors such as Google, Microsoft and Yahoo provide competitive geospatial services based on global map and satellite image. But the relatively low level of platform technologies has not rapidly increased the land information and geospatial service markets in Korea. For the ubiquitous next generation Internet, as a one of the R&D projects by Korean Land Spatialization Group, the project for platform technologies has being made to provide customized land information and geospatial service. The platform technologies can be categorized for streamming, mashup and geosearch. More specifically, the 2D/3D Hybird streamming engine, mashup engine for u-GIS service and next generation search engine for land information have being developed. In this context, the strategies for efficient development and use of geoweb platform technologies are required. This study surveys the present geospatial products and services using of platform technologies to propose the strategies for efficient development and use of platform technologies. The strategies for efficient development and use of platform technologies can be proposed focusing on target market and each of platform technologies.

This study is to suggests the vision and policy issues on National Geographic Information System in Korea. Firstly, this study is to describe the current situation and problems of national geographic information. ${\ulcorner}$The Second national geographic information plan${\lrcorner}$ consist of 47 projects include national level. For the purpose of third NGIS plan, diverse problems suggested on spatial information computierization, application, distribution. Secondly, we conducts an analysis of national geographic information demand. According to the analysis results 'cyber geospace' is the key issues in near future. In order to construct the ${\ulcorner}$Integrated Digital Territory${\lrcorner}$ in the 21st Century, the current promoted project for the national geographic information constuction needs to be more developed. In this regard, it is necessary to implement ${\ulcorner}$Integrated Digital Territory${\lrcorner}$, enhancing the usability of NGIS, creating the 'cyber geospace' and intelligent territory.
