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

The provision of spatial data is a key infrastructural requirement for the promotion of economic growth, environmental quality, social progress, etc. 4S technology integrates 4 kinds of systems that process spatial data: GIS (Geographic Information System), GNSS (Global Navigation Satellite System), ITS (Intelligent Transport System), and SIIS (Spatial Imagery Information System). Spatial data processing field is expected to get synergy effect and overcomes development limit of individual unit technology via 4S technology. This paper discusses both the development of 4S-kernel technology and the construction of 4S-based framework, In the development of 4S kernel technology, we will concentrate on the following issues: the development of 4S base components for reciprocity integration among GIS, SIIS, GNSS and ITS technologies, the development of 4S-Mobile S/W and H/W, 4S-Van components, and national LBS technologies. And in the construction of 4S-based framework, we will especially concentrate on the ISP for overall 4S technologies, the international cooperative research center, and the guide model deduction for supervision and certification of 4S projects. Finally, we examine about how the construction of 4S-baed framework affects 4S industry.

현재, 극장 사운드를 중심으로 객체기반 오디오 기술을 포함하는 하이브리드 포맷의 사운드 서비스가 점차 확산되고 있으며, 미국, 유럽, 한국 등에서는 차세대 방송용 오디오에 객체기반 오디오 기술의 도입을 적극적으로 고려하고 있다. 객체기반 오디오 기술은 콘텐츠의 제작단계에서 재생환경을 고려할 필요가 없고, 현장의 음향을 신호와 3차원 공간정보로 구분하여 음향공간의 정보를 그대로 표현함으로써, 재생단말에서 3차원 공간정보를 활용하여 재생할 수 있게 한다. 이러한 객체기반 실감음향 기술개발을 위해서는 편리한 제작 및 3차원 공간정보 표현 기술이 필요하며, 청취환경에서는 객체기반 실감음향 콘텐츠를 제작자의 의도대로 렌더링할 수 있는 재생 및 제어 기술이 필요하다. 이에 객체기반 실감음향 기술이 포함되는 하이브리드 오디오 기술의 현황에 대하여 살펴보고자 한다.

최근 수요가 급증되고 있는 u-City의 경우 성공적인 구축을 위하여 도시통합운영센터라는 개념을 도입하여 추진하고 있으며, 나아가 이를 보다 확장시킨 개념인 도시통합운영체계의 중요성이 강조되고 있다. 이처럼 u-City의 핵심기반으로서 도시통합운영체계의 중요성이 증대되고 있는 가운데, 효율적인 도시통합운영체계 구축을 위해선 공간정보 활용이 필요하다. 즉, 지자체에선 오래전부터 GIS 정보화 사업을 추진하고 있으며, 공간정보를 구축 활용하고 있다. 효율적인 도시통합운영체계 구축을 위해선 공간정보의 활용은 필수적이며, 이는 u-City 추진의 핵심적 기반이 될 것이다. 본 연구에서는 u-City 도시통합운영체계에서 공간정보를 효율적으로 활용을 위해 u-City의 도시통합운영서비스와 관련하여 공간정보의 활용성과 활용방안을 제시하고자 한다.

3차원 공간정보는 u-Korea, 전자정부, 유비쿼터스, LBS등의 기반 인프라 및 3차원 그래픽 처리기술, 가상현실 기술 등의 종합적으로 적용되는 고부가가치 통합 기술로 필요성이 부각되고 있다. 본 연구에서는 컴퓨터 그래픽스 분야에서 많이 적용되고 있는 공개 그래픽 라이브러리인 OpenGL(Open Graphics Library) 기반의 3D-GIS 가시화 어플리케이션 아키텍쳐를 중심으로 렌더링 기법을 분석하고자 한다. 한편 본 연구의 실험은 Visual Studio.NET환경에서 3D-GIS 모델 Prototype을 구현하여 수행하였으며 향후 실시간 모바일 3D-GIS 렌더링을 위한 기반 기술로 적용될 수 있는 OpcnGL-ES의 확장 가능성을 검토하고자 하였다.

Recently, Construction business is changing from on the ground to underground space because of deficit of developing space, creation of green space and of incremental of land compensation expenses. Meanwhile, 3D Topographic, Marine and Cadastral maps need to have Spatial Interrelation. Also, understanding of the information is also needed. Spatial information object registration system is impossible to contact and understanding intelligence mutually because the former one is managed as automatic ID system. Therefore, 3D Object information ID System of underground space is managed based on Object Identifier. Construction of Spatial information integration ID System is required and it will offer Division Code (Ground, Index, Underground) and depth information. We are defined and classified Under Spatial Information in this paper. Moreover, we developed the integration ID System based on UFID for cadastral information Construction. We supposed underground spatial information DB Construction and a developed the way of exploiting 3D cadastral information system through the study. The research result will be the base data of Standard ID system, DB Construction and system Development of National spatial data which is considered together with spatial interrelation.

With the advent of uniquitous life, changes of users' demands make a public library accomplish roles and functions of a complex service center providing information, education and culture service. As a multi-function center, a public library provides various services based on physical and digital space in ubiquitous environment. Information commons is a basement of physical space in an u-Library. Especially, with the advent of ubiquitous environment, design and use of physical space will be a critical issue for a public library to perform its role and function as a multiple complicated space. This study derives facilities and components for designing and implementing information commons in a public library as a physical space. To perform the goals, this study focuses on the newest trends and requirements through literature study, case study and survey. As a result, this study proposes components of facility and principles of design to implement information commons as a physical space in a public library.

In this paper, we preset a method for the development of u-GIS outdoor augmented reality(AR) system. The proposed system is consist of three parts. First, sensor acquisition and calibration for AR, Second, camera and sensor based tracking for AR, Third, integration of sensor information and 3D models. We combine spatial information of real and virtual spaces through u-GIS AR system.
