Geo-spatial information system technology and cartographic modeling techniques were used as a way to Improve the land use planning process. Off-road vehicle(ORV) trails, timber harvest sites, timber haul mads and wildlife ruffed grouse habitats areas should be allocated together in the Wayne National Forest in the United States. Automated spatial cartographic models were developed to resolve the conflicts of the multiple land use allocation. The techniques of descriptive and prescriptive modeling made the multiple land use allocation efficient and effective.

The purpose of this study is to suggest the way of analyzing land uses to utilize GIS in the field of urban planning. The Saga Land Information System was built in early 1990s. The building data were inputted by house investigation map(1/1,000) using digitizer. And urban planning basis investigation data in 1994 were utilized as the attribute data. Also, by calculating specialization factor, we distinct the characteristic of every land use of the city, and it compares every land use zone. This study calculated and compared an observation frequency and an expectation frequency of every building use and land use zone. We found that the use of the building tend to be controlled and guided by the land use zone.

The goal of this research is to suggest the desirable directions of the land policies implement system based on analysis of existing those of Korea with the paradigm shift of land policies. We classify the land policies into land ownership, land use, land development and land management ones, and then analyze their implement system characteristics. The results are follows : firstly, the land policies implement systems have been set to large scale and rapid development. Secondly, although the systems have been specialized by their areas, the comprehensive manage systems for the harmony between development and conservation are lacking. Thirdly, the parts of the central government powers related to land use has been hand covered to local governments. And the participations of residences private companies have enlarged in the land development. Fourthly, the purposes of the information management on land use have been changed from tax collection into planned land use, but the information management has not met the need of planned land use. This study shows that firstly, the implement system focusing on large development projects might be no longer effective because of high possibility of the property prices stabilization, so moderately small ones must be found. Secondly, the system cope with the climate change and to realize the efficient utility of land is needed. Thirdly, it is necessary to take the actual measures to participate a variety of subjects. Fourthly, the system modification of the land information manage system as land policies infra is also needed to establish integral land policies.

Satellite images have been used to obtain land cover information that is one of important factors for hydrological analysis over a large area. In urban area, more detailed land cover data are often required for hydrological analysis because of the relatively complex land cover types. The number of land cover classes that can be classified with traditional multispectral data is usually less than the ones required by most hydrological uses. In this study, we present the capabilities of hyperspectral data (Hyperion) for the classification of hydrological land cover types in urban area. To obtain 17 classes of urban land cover defined by the USDA SCS, spectral mixture analysis was applied using eight endmembers representing both impervious and pervious surfaces. Fractional values from the spectral mixture analysis were then reclassified into 17 cover types according to the ratio of impervious and pervious materials. The classification accuracy was then assessed by aerial photo interpretation over 10 sample plots.

도시재생을 효율적으로 수행하기 위해서는 시간 공간속성을 가진 지표데이터를 기반으로 한 종합적인 분석이 가능한 진단체계의 구축이 필요하다. 본 연구에서는 이러한 진단체계 구축의 일환으로 도시 재생 대상지 선정 모듈을 개발하였다. 대상지 선정방식은 인구사회, 산업경제, 물리환경 부분별 진단지표 DB를 구축하고, 각 부문별 조건에 부합되는 지역을 선정하도록 하였다. 기준으로 설정된 조건 이외에 상세 분석을 위한 지표 조합방식을 도입하여 상세분석이 가능하도록 하였다.

This study examines the unique characteristics of the parcel identification number especially in developing the Korean land information system(KLIS). There are several limitations in establishing KLIS in terms of the location identification. Therefore, it is necessary to develop the appropriate parcel identification number system in Korea including the road identification systym and the three dimensional parcel identification system. The exact parcel bounary also needs accurate surveying and registration.

홍수유출의 특성에 영향을 미치는 요소로는 강우량과 토지이용, 유역의 경사, 유로연장등이 있다. 이중에서도 유출시스템에 영향이 큰 요소중에 하나로서 토지이용상태가 있다. 토지이용은 불변하지 않는 값이며 매년 토지이용상태가 변화하고 있다. 특히 개발의 진행속도가 더욱 빨라지고 있는 현대에서 홍수유출을 산정하는데 있어 최신의 토지이용상태를 반영하는 것은 매우 어려운 일이다. 그러나 현실적으로 실무에서 사용하고 있는 토지이용도는 대부분 10년이상 전의 자료를 사용하고 있는 실정이다. 그러나 인터넷의 발달과 인공위성 자료, 항공사진등의 정보를 구하는 수월해짐에 따라 최신의 지형 및 토지이용의 변화를 반영할 수 있는 방법이 다양해지고 있다. 본 연구에서는 항공사진을 이용하여 토지이용상태를 파악하고 유출계수를 산정하여 유출특성을 비교하였다.

Land assessement is a procedure that assesses developmental, agricultural or heritage suitability of land parcel according to such criteria as soil, location and usability. There are much problems to execute land assessment by law. Problems include inadequate basic data, lack of linkage with the spatial planning system, and inefficiency in operation. The purpose of this study is to investigate methods of developing land assessment as a sustainable land use management tool in a Korean context, using case study. In the case study, land assessment will be executed through GIS- based assessment method. On the basis of the results of this case study, practical and institutional problems are described, and technical and institutional solutions are suggested.

The purpose of this study is to establish a Zone-Based Land Use Information System(ZBLIS) using digital topographic maps and public statistics data with a case for Pohang. The Basic Spatial Units(BSUs) used in ZBLIS is the administrative district units(Dong and Lie), and larger or smaller spatial units than this are brought out from BSUs. In the first step, the structure of ZBLIS is constructed to choose Analysis Zone on the top menu, and in subsequent steps, to choose Analysis Categories on sub-menu in terms of dialog windows, and then to choose Analysis Sub-categories and Analysis Theme. The 11 Analysis Categories are consisted of Population, Land Use, Transportation, Industry and Economy etc.. In this case study, it is found that there occur some technical problems in the process of making base-map from digital topographic maps, and inputting attribute data to this base map. For each of these problems, some handling method are recommended.
