The architecture of the National Geo-spatial Information Clearinghouse Network (NGICN) is suggested in this paper. We described the function and relationship of six elements of the NGICN. The elements are clearinghouse network gateway, clearinghouse node, geo-spatial data server, communication network, protocols and standards, and clients. The NGICN suggested in this research will prevent the duplication and improve the value of the database, and persuade the institutes or enterprises in the private sector to participate in producing the geo-spatial database. Finally it will setup the business of producing, circulating and utilizing the geo-spatial information as a new bases of Info-Communication Industry.

Government has established and operated GIS Data Base in such fields as land-use, road, and underground facilities since 1995. Based on these circumstances, the importance of spatial information industry began to emerge and accordingly MLIT (Ministry of Land, Infrastructure and Transport) established "National Spatial Information Policy Master Plan" and "National Spatial Information Policy Action Plan". However, compared to other fields of transportation, the spatial information data base for railway facilities are not established and provided systematically. As shown in 'Korea National Spatial Data Infrastructure System', only 'transportation information' as an related information and 'transportation' field as an administrative information are included in the system. Detailed information for railway and its facilities are not included in the system. The reason why detailed information for railway facilities are not included in the system is that regulations for establishing and utilizing the spatial information of railway and its facilities are imperfect. In this study, trend of establishing spatial information and regulations related to railway and its facilities are reviewed. Through this review, improvement items such as complementing existent laws and establishing organization for managing spatial information data of railway are deduced and suggested. Based on this research 'Korea National Spatial Data Infrastructure System' could set a legal fundament and both integrated maintenance and operation of railway facilities could be possible.

The national spatial information systems project which is promoted by our country has been extended from existing 2-D geographic information to 3-D spatial information as the basic geo-spatial Information. Most of the construction of the ground geo-spatial information are completed or underway, on the other hand, the construction of the subsurface geo-spatial information has difficulty caused by the lack of the drilling data characterizing the subsurface. In terms of the construction of the geo-spatial information of the subsurface, the subsurface information is constructed and managed by the domestic institutions, but the subsurface information which is possessed by the institutions was not shared mutually so it is managed inefficiently. This study presented the 3-D national underground information DB design by dividing with the ground DB item which configures the state of the ground and the soil DB item which configures the state of the soil in order to increase the efficiency of the construction of the subsurface spatial information. The implementation & utilization of the national underground information application technology was reviewed by applying the constructed DB to the actual model area, and the national underground information knowledge-based community establishment plan was presented.

This study aims to establish the quality management method for spatial data construction process. Total 17 regulations related to spatial database construction and major aerial survey firms were analyzed in terms of working process, equipments, accuracy of results. It is standardized the process of making new digital maps using aerial photography, revising existing digital maps, producing digital elevation models and developing imagery maps. Quality checking factors for spatial data construction process are also established.

After 1995, as a part of national geographic information system project, there are a lot of researches about combinations and connections of national geographic information system. However, systematic standard for combinations and connections of geographic information is uncertain, and each organization has different identification system which leads to difficulties in connection of geographic information system. This study suggests repeating method about geographic information objects to grant UFID based on national standards of geographic information system, and analyzes the repeating rate.

This paper presents the development of a certain highly efficient authoring tool for constructing realistic 3D virtual space using image-based rendering techniques based on a virtual space map. Unlike conventional techniques such as TIP, for constructing a small 3D virtual space using single image, the authoring tool developed herein produces a wide 3D virtual space using multiple images. This tool is designed for constructing each small 3D virtual space for each input image, and for interconnecting these 3D virtual spaces into a wide 3D virtual space using a virtual space map. The map consists of three elements such as specific room, link point and passageway, and three directions. It contains various information such as the connection structure, the navigation information and so on. Also, the tool contains a user interface that let users construct the wide 3D virtual space easily.

정부에서는 NGIS 이단계 사업의 추진에 앞서 위성자료를 활용한 공간영상정보를 구축하여 기존에 NGIS 일단계에서 구축된 기본도와 NGIS 이단계에서 구축예정인 다양한 주제도와 공통주제도, 나아가 주요 분야별 프레임워크데이터의 효율적 갱신에 활용할 예정이다. 이러한 공간영상정보는 동시성과 주기성, 광역성을 가지고 1-2m의 고해상도까지 정보의 제공이 가능하므로 향후 주제도의 구축과 갱신에 기여도가 매우 높으리라 예상된다. 아울러 기존에 오랜 기간 제작된 항공사진을 적정 해상력으로 스캐닝하여 공간DB화 함으로서 위성자료와 연계된 과거와 현재의 시계열 자료를 확보함으로써 보다 다양한 대국민 정보서비스가 가능하리라 판단된다. 이와 함께 지방자치단체에서도 그동안 축척된 항공사진을 공간DB화하여 도시계획과 녹지관리, 하천 및 환경관리 등을 위하여 활용이 크리라 예상된다. 본 연구에서는 이를 위한 공간영상정보화된 항공사진의 관리와 제공을 위한 관리시스템의 개발과 정확도 관리 방안, 검수 방안, 사용자를 위한 메타데이터 제공방안 등을 제시하고자 한다.

도시계획과 환경정책의 경우 장기적인 고려가 필요하므로 도시기본계획과 환경보존계획을 주기적으로 수립해야만 한다. 특히 환경보존계획의 경우 환경속성정보의 분석은 물론 환경공간분석을 통해 대상영역에 대한 환경관력 공간분석이 필요하다. 그러나 환경관련자료가 분산되어 있어 데이터베이스구축이 불편하다. 본 연구에서는 환경공간분석자료구축을 위한 데이터 소스를 정리하고 효율적은 구축방법과 함께 개선방향을 제시하고자 한다.

Most of the administrative works are executed based on the address. Therefore, spatial information is an essential factor for administrative works. So far, many systems, which apply spatial information to administrative works, have been implemented. However, there is little approach to apply spatial information to road occupation permit works. In this paper, we introduce system implementation plan for applying spatial information to road occupation permit administrative works. System implementation plan includes work analysis, applying scenarios extraction, system function extraction, and datamart construction plans. First, work processes and activities are defined based on the analysis of work handbook. Also, activities are displayed in diagram. Second, scenarios applying spatial information to road occupation permit works are extracted. Third, we derive service functions for system, which realize work processes and applying scenarios. Finally, spatial information datamart construction plan is established. Proposed system implementation plan in this research includes application architecture and part of data architecture. For implementing the system, plan for hardware and software architecture should be studied.

본 연구의 목적은 공간데이터 구축시 아직까지 체계화되어 있지 않은 공간데이터의 품질 평가요소를 정립하는데 있다. 총 17개의 국내 공간데이터 품질관련 법규를 구축 공정, 작업방법, 장비, 정확도 등을 중심으로 분석하였다. 항공사진 촬영이 가능한 대규모 업체를 대상으로 작업순서, 사용장비, 작업순서 전후의 결과물의 정확도를 중심으로 조사하고 팀장급 직원들을 대상으로 현행 관련법규와 실무의 차이에 대하여 조사, 분석하였다. 조사, 분석한 내용을 기반으로 공간데이터의 구축공정을 항공사진을 이용한 수치지도 신규제작, 기존 수치지도 수정제작, 영상지도제작, 수치표고모델 구축 공정으로 구분하고, 각 공정별로 생성되는 공간데이터의 품질을 체크할 수 있는 요소들을 정립하였다.
