The improved accuracy of the Land Cover/Land Use Map constructed using Hyperspectal Satellite Image and the possibility of real time classification of Land Use using optimal Band Selective Factor enable the change detection from automatic classification using the existed Land Cover/Land Use Map and the newly acquired Hyperspectral Satellite Image. In this study, the effective analysis techniques for automatic generation of training regions, automatic classification and automatic change detection are proposed to minimize the expert's interpretation for automatic update of the Land Cover/Land Use Map. The proposed algorithms performed successfully the automatic Land Cover/Land Use Map construction, automatic change detection and automatic update on the image which contained the changed region. It would increase applicability in actual services. Also, it would be expected to present the effective methods of constructing national land monitoring system.

도시토지이용의 문제는 인구와 시설이 증가함에 따라 점점더 심각해지고 있으며 토지이용계획은 도시계획에서 가장 중요한 부분이다. 따라서 도시토지이용의 현상을 파악하고 미래를 예측하는 것은 토지이용계획의 핵심적인 과정이라 할 수 있다. 토지위에서 일어나는 제 현상들을 이해하기 위해서는 정확한 토지정보를 확보하는 것이 중요하며 토지이용의 효율적인 관리를 위해서는 종합적인 토지정보체계를 구축하는 것이 필요하다. 본 연구에서는 도시의 토지이용분석을 위한 기본적 단계로서 토지정보체계의 기능, 목표, 구성, 활용방안등을 고찰하고 데이타베이스를 작성하는데 필요한 자료선정과 입력사항을 국내외 한가지 사례와 일본의 사례를 통하여 분석함으로써 토지이용분석을 위한 토지정보체계의 구축방안을 모색하였다. 이러한 연구를 통하여 토지이용의 시계열적 변화패턴을 파악하고 그 요인을 분석함과 동시에 장래의 변화가 예측되는 토지이용계획을 수립함으로써 바람직한 토지이용을 유도하고 조정가능한 방안을 강구할 수 있을 것으로 사료된다.

Because of the limited land resources, an efficient land use management to reach the sustainable development policy has become an urgent call in Taiwan. A long-term project entitled 'National land use monitoring program-the establishment of a land use change detection system' has been jointly conducted by both National Central University and Ministry of Interior since year of 2001. The main aim of the project is to use the remote sensing images to detect the land use changes on a national scale. This plan has been put into practice and indeed provides an effective assistance for land management.

In 2003, "The National Land Use and Planning Act" (NLUP Act) was enacted unifying two old laws; "The Urban Planning Act" enacted in 1962 and "The National Land Use and Management Act" enacted in 1972. One of main reasons of unifying two acts was to extend urban planning-based development systems to rural areas for preventing uncontrolled urban sprawl in rural areas and enhancing or settlling plan-based land use system in rural areas. This paper is conducted with the following specific objectives: i) to critically review the contents of NLUP Act in terms of rational rural land use planning; ii) to evaluate plan-based land use practices in rural area by NLUP Act; iii) to appraise performance level for prevention against unplanned development activities in rural areas by NLUP Act. To accomplish these objectives, we surveyed actural state of rural land use and development system by the new act in two case study areas. Ansung city in Gyeongi province as an urban sprawl region and Hamyang county in Gyeongnam Province as a remote rural area. Study results ascertained that the new act can not effectively control rural land use and not prevent over-use of agricultural land in the positive and effective ways because of followering three points.

Although sustainable development of a city should in theory be based on updated spatial information like land cover/use changes, in practice there are no effective tools to get such information. However the development of satellite and sensor technologies has increased the supply of high resolution satellite data, allowing cost-effective, multi-temporal monitoring. Especially KOMPSAT-1(KOrea Multi-Purpose SATellite) acquired a large number of images of the whole Korean peninsula and covering some large cities a number of times. In this study land-use patterns and trends of Daejeon from the year 2000 to the year 2003 will be considered using land use maps which are generated by manual interpretation of multi-temporal KOMPSAT EOC imagery and to show the possibility of using high resolution satellite remote sensing data for urban analysis.

The primary purposes of this study are to identify the characteristics of land development in urban area through GIS and remote sensing techniques and to provide useful implications for urban spatial policy. To perform these tasks, Daegu metropolitan city and its vicinities were selected as a study area, and remote sensing data and attributed data were collected, organized and analyzed. This study focuses on the following three steps. First, it identifies the characteristics of land development in urban areas by utilizing multi-temporal satellite image data (Landsat TM, 1980, 1985, 1990, 1995, 2000 and 2005). Second, it tries to find an answer on a critical question concerning land use conversion, i.e., which land use leads expansion of urban area? Third, it derives implications for urban spatial policies based on these findings. The characteristics of the urban extents tell us that the main land use converted into urban use from non-urban uses is green areas. The public sector, central and local governments, leads the land use conversions of suburban lands as exclusive legal body to issue permission of land use change. Based on these findings, this study concludes that the more systematic and technically advanced management tools should be utilized for more effective spatial management for urban growth.

「국유재산법」 개정으로 국유지 활용여건이 개선되었다. 새정부도 민간투자활성화와 재정투자 여력 확보를 위해 국유지 활용 필요성을 제시하고 있다. 본 연구는 이러한 정책기조 변화에 맞춰 일본의 국유지 활용정책과 유효활용 사례를 살펴보고 국유지 관리와 활용증진 관점에서 정책적 시사점을 찾아 보고자 하였다. 일본의 국유지 활용정책 방향은 효율적인 국유지 관리를 통해 보유 중인 국유지의 최적이용을 유도하며, 국·공유지 연계와 민간참여 등을 통해 적극적인 국유지 활용을 도모함으로써 국유지 가치를 높이고 미이용 국유지를 감소시킴으로써 궁극적으로 저가에 국유지가 매각되는 것을 억제하는 방향으로 정책이 추진되고 있는 것으로 나타났다. 국유지 유효활용 촉진을 위해 먼저 명확한 정책 방향을 정립하는 것이 필요하다. 그리고 투명한 정보공개시스템 구축, 부처간 이해관계 조정이 가능한 강력한 컨트롤타워 구축이 요구된다. 효율적인 국유지 활용을 위한 정책수립의 출발점은 실질적인 국유지 주인은 국민이라는 인식의 전환이다.

This paper deals with the study of the effective reflecting area of the land targets for the improvement of the map of the Radar Simulator, through the analysis of the pictures on P.P.I Scope. It is very important to anticipate the effective refiecting area of land marks, either forinterpretation of radar scope or for simulating accurately the radar scope, but has seldom been studied theoretically or experimentarily, especially on the stand point of simulating the radar scope. Most of the maps of Radar Simulator in use are made without consideration of the effective reflecting area of land marks, so that the P.P.I. Scope of the Radar Simulator may show much different pictures from the actual shore line and other targets. This paper has derived the following conclusiions by experimental procedures. 1. The effective area of the land target greatly varies according to the gradient of the contours, roughness and material of the land surfaces, so that simulator maps of uniformly coated land taret practically used now many be effectively improved by varying the intensity of the land marks proposed in this paper. 2. The intensity of the land targets on the P.P.I. is also related much to the distance from the radar, so that the precalculation of this effect may results in a much simulated P.P.I. picture improved. 3. If the ambient condition is constant, the intensity of the picture increases as the height of the targets is increased.

본 연구는 전라북도 지역을 대상으로 비교적 광범위한 지역에 대한 국토이용 현황을 분석하기 위하여 최신의 디지털 토지이용현황도(이하, 토지이용현황도) 및 토지이용현황도 활용시스템의 활용방안을 연구하였으며, 이를 토대로 국토의 균형적 발전을 도모할 수 있는 효율적 국토이용계획 수립을 위한 의사결정지원은 물론 토지이용현황도를 이용하여 효율적인 국토이용현황을 분석할 수 있는 최적의 방안을 제시하고자 하였다. 토지이용현황도는 본 연구에서와 같이 광범위한 지역의 종합적인 토지이용현황에 대한 분석을 할 수 있게 함으로써 국토의 균형적인 개발계획을 수립하는 것은 물론 개발에 따른 환경영향 예측, 홍수와 같은 재해분석등 다양한 분야에서 기반자료로서 그 활용성이 크다고 할 수 있다. 따라서 본 연구를 계기로 아직까지는 홍보 및 사용방법의 인식부족으로 그 활용성이 미비한 토지이용현황도가 다양한 분야에서 적극 활용될 수 있기를 기대 한다.

The Korean government has introduced land policy reform measures recently, in order to stabilize the circulating system of land, without a parent law involving effective land use. The measures aim to change the pattern of land market rather than the pattern of land use. Expecially, the excessive profits tax on land intends to redistribute the owernership of residential land, and to recapture windfall gains on an accrual basis. However, it may incur secondary gains in macro economics and an unintended reduction of urban land supply in the land market. This paper aims to study empirically the impact caused by the excessive profits tax on land, and to promote urban land supply. Ultimately, this paper can be regarded as an interim report on outcome of research projects which aim to propose a method of urban land supply suitable to an advanced society.
