국립산림과학원 산림조사과에서는 지식정보화사업의 지원 하에 남한 전체 낱장/정사항공 사진 영상 DB툴 구축하고， 항공사진검색시스텀 (aerophoto.kfri.go. kr)을 개발하여 대국민 인터넷 서비스를 제공하고 있다. 본 논문에서는 5TB 대용량 항공사진 원본 영상과 메타자료를 웹 지리정보 서비스에 적합하도록 자료의 변환 방식，소프트웨어와 하드웨어의 최적 구성안, 그리고 응용 검색 시스템의 개발 기능을 소개 한다. 또한，항공사진 웹 검색 시스템은 벡터 지리정보와 항공사진 영상을 각각 전송하여 융합하고 분석하는 기능을 담당하는 클라이언트 모듈을 한정된 네트워크 환경에서 대용량 자료의 검색 속도 향상을 위하여 비동기식 처리 방식으로 개선하였다. 그리고 국가 지리정보 인프라인 정사항공사진 자료를 타 시스템과 연계 활용하기 위한 방안으로 ESRI ArcGIS 의 Plug-in 적용 사례를 제시한다.

국가지리 정보체계 (NGiS: National Geographic information Systems) 기본계획 하에서 국가수치기본도가 완성되었음에도 불구하고 교통부문에 GIS의 활용이 미흡하다. 그 이유는 기존 교통관련 S/W가 교통GIS DB를 받아들일 수 없기 때문이다. 이러한 시점에서 본 연구에서는 NGIS에 기초한 교통GIS DB의 이용활성화의 일환으로 교통GIS DB와 기존 교통계획S/W와 상호 Interface할 수 있는 전환 모듈을 개발하였다. 구체적으로는 기존 GIS S/W를 활용하여 교통GIS DB와 기존 교통계획 S/W인 TRANPLAN간의 연계모듈을 개발하였다. 최종적으로는 개발한 연계모듈을 서울시 강남구, 서초구와 경기도 과천시, 용인시에 걸친 일대를 시범지역으로 적용해보았다.

Recently, because of the extensive use of geographic information in the various fields, the requirement for the easy circulation and utilization of the various geographic information among the individuals, organizations, societies and countries is raised. In order to support the interoperability of the heterogeneous geographic information in the various fields, OGC(Open GIS Consortium) proposed the GML(Geography Markup Language) specification that defines the XML encoding rule about the heterogeneous geographic information. In addition, ISO/TC 211 adopted the GML specification to make it as the international standard. Therefore, in this paper we first analyzed the GML 3.0 specification in detail that can support the interoperability of the heterogeneous geographic information. And then we suggested and applied the mapping rule that define the encoding method to improve the encoding process easily and efficiently. Finally we designed and implemented the GML 3.0 encoding system using the mapping rule to encode the geographic information that was constructed in spatial databases into the GML 3.0 document. Especially, we used ZEUS as a spatial database system to test our encoding system in this paper.

The purpose of this paper is to examine trends of the GIS education in the school's education of the USA, especially the geography education, which the application of GIS is activated in the life. In addition, in this paper are explored possibilities of GIS education in the geographical education of Korea throughout the consideration of the USA case. There are some backgrounds of the activation of GIS education in the USA, They can be characterized as (1) the achievement of the validity between the geographical importance in the realm of the national policy and GIS education, (2) offering standard indications for GIS education and gradually minimizing school teachers' work-loads, (3)the establishment of the network of GIS stake-holders and their cooperation, (4) the attraction of school students through case study-centered education, and (5) the share of GIS education-related information. These shall be considered to introduce actively GIS education into the geography education in Korea.

In 1995 of May, the Ministry of Construction and Transportation (NOCT) developed the First Nation-wide Master Plan of GIS. It is set up in response to an increasing and various demands on spatial informations. Until now, a set of diverse projects related to spatial information have been proposed and executed. However, cost-benefit analysis of investment and decision making for alternatives have not been carried out appropriately because scientific evaluations for obtaining efficiency and economical validity of investment have been deficient. Optimum decision making for projects based on itemized priority order using effect or cost of proposed alternative plan is a fundamental expedient for demonstration of propriety of projects and enhancement of efficiency of investment. From such understanding, this paper applied the analytic hierarchy process (AHP) technique to the cost required to construct a GIS so that analyze the weight of each cost factor.

지자체 GIS 정보화가 확산되어감에 따라 구축된 공간정보의 활용확산, 타 정보와의 연계 등의 요구가 증대되고 있으며 지자체 GIS 통합 연계는 지자체 정보화의 핵심으로 부각되고 있다. 그러나 많은 지자체에서는 도로, 상하수도 등 공간정보 수요가 높은 업무 분야를 중심으로 지자체 GIS 통합연계를 추진하고 있으며, 지자체 지리정보 담당부서의 중심으로 추진되고 있어 지자체 전 부서 대상의 공간정보 활용에 대한 한계가 있다. 이러한 한계를 극복하기 위해선 지자체 내 전부서에서의 공간정보 활용을 위한 지자체 GIS 통합연계 고도화 모델이 필요하다. 지자체 GIS 통합연계 고도화 모델은 지자체 지리 정보 담당부서 중심의 통합연계에서 확대하여 지자체 전 부서 및 국가적 차원에서의 협력체계를 고려한 모델로서 지자체의 수평적 수직적 통합연계 모델이다.

This study aims to establish a strategic NSDI (National Spatial Data Infrastructure) model for developing countries based on good practices in the Republic of Korea. The Republic of Korea is a unique country in the world, which has become a developed country from a recipient of international aid since the Korean War in 1950. The rapid economic growth can be mostly attributed to the IT technologies and the Republic of Korea's NSDI efforts as a good practice could provide useful lessons for developing countries. This study consists of theoretical reviews, interviews of Korean NSDI experts, analysis for lessons learned, a summary of the lessons in terms of Six NSDI components and finally a strategic NSDI model for developing countries. The NSDI model is structured by (1) implementation strategies suggested for geospatial data, capacity building, geospatial platform, and cost-effective management with partnership, (2) a roadmap of important NSDI tasks and activities, and finally, (3) a harmonized approach for successful NSDI implementation.

Providing real-time location information is emerging as a major goal of the national industry. In order to provide such real-time location information (3D spatial information), it is essential to develop a technology for a satellite positioning method. Therefore, the country continues to make efforts to increase satisfaction with the needs of consumers by introducing the Network RTK GNSS method. In this study, among the Network RKT GNSS(Global Navigation Satellite System) methods provided by the National Geographic Information Service, continuous observation and single observation were measured at the integrated reference point using VRS(Virtual Reference Station) and FKP(Flӓachen-Korrektur Parameter) to evaluate accuracy. In addition, we aim to maximize efficiency by presenting accuracy on the rapidly increasing Network RTK GNSS method in the field.

Geo-special technologies are being adopted in variety fields since the 3rd NGIS plan that was started at 1996. However, the required system or structure to guarantee the up-to-date validity and accuracy of the geospatial data - the most fundamental elements of the technology - was not constructed yet. All the activities related to geospatial data, including topographical map and numerical base map, are all implemented in separate way; from change of geographical objects and features, data gathering, and database construction to distribution, transfer and sharing of these data. The data model that links all the activities are required that enables consistent data-flow and effective and systematic work-flow. In this study, economic data renewal and exchange method was proposed, and benefit-cost analysis was implemented by comparing the conventional work-flow to newly proposed work-flow. The case study was implemented using the model that was adopted in Daegu metropolitan city, and the model was developed by reflecting these results.

The purpose of this study is price determination for KLIS (Korea Land Information System) which Korea government established. For this purpose, I analyzed cost accounting and made the KLIS selling price according to selling amount, recovery rate and information volume. In case of recovery rate, the cost was expensive but, in case of information volume the cost was cheap. So, the price determination for KLIS should be resonable according to information volume considering GIS revitalization.
