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.

The problems of urban land use are becoming worse by the increase of population and facilities. Land use planning is the major part of comprehensive city plan¬ning. Understanding and forecasting the present and future conditions of land use are the main process of land use planning. In order to comprehend the various phenomena which occured on the land, collecting accurate land information is the most important thing for the effective management of land use. Therefore, it is necessary for us to establish the land information systems. In this study, theories of functions, objectives, components and applications of land information systems were investigated as the basis of this research. Case studies of Korea and Japan were examined, not only for the desirable selection of input data items, but also for the effective land use anslysis in land information systems. Through this kind of study, we can anslize and understand the changing patterns of land use over time, and we can also prepare a more desirable and adjustable land use plan-ning programs for the future.

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.

With the revision of the 「State Property Act」, the conditions for using state-owned land have improved. The new government is also suggesting the necessity of using state-owned land to revitalize private investment and secure financial investment capacity. In line with these policy changes, this study examines Japan's policy on the utilization of state-owned land and effective use cases, and seeks to find policy implications from the perspective of managing and promoting the use of state-owned land. The direction of Japan's public land utilization policy is to induce optimal use of state-owned land through efficient management, and to increase the value of state property by promoting active use of state-owned land through linkage of state-owned and public land and private participation, etc. It appears that the policy is being pursued in the direction of suppressing the sale of state-owned land in the country. To promote the effective use of state-owned land, it is necessary to establish a clear policy direction first. In addition, the establishment of a transparent information disclosure system and the establishment of a strong control tower capable of coordinating interests between ministries are required. The starting point of policy establishment for efficient use of state-owned land is to change the perception that the actual owner of state-owned land is the people.

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.

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.
