The Digital Terrain Model(DTM) data in the Geographic Information System(GIS) needs to be interpolated for various purposes. Three interpolation methods-Bilinear, Bicubic Spline, and Gregory-Newton interpolation-were used, compared, and analyzed in terms of the visual comparison and numerical analysis in the hilly terrain and relatively flat terrain.

The purpose of this paper is to study the using method of the satellite image processing and GIS(Geographic Information System) map-algebra for the sustainable (land-use) plan. The research has been made by the two kinds of approaching steps. The first one is to allocate the sustainable zoning which is applicable to the environmental and the legal restriction elements base on space structure. The second one is to make a more sustainable plan through the extension of analysis range and the inclusion of analyzed environmental impacts within the plan making processes.

The purpose of this study is to present a standardized scheme for providing agriculture-related information at various spatial resolutions of satellite images including Landsat＋ETM, KOMPSAT-1 EOC, ASTER VNIR, and IKONOS panchromatic and multi-spectral images. The satellite images were interpreted especially for identifying agricultural areas, crop types, agricultural facilities and structures. The results were compared with the land cover/land use classification system suggested by Ministry of Construction & Transportation based on NGIS (National Geographic Information System) and Ministry of Environment based on satellite remote sensing data. As a result, high-resolution agricultural land cover map from IKONOS imageries was made out. The results by IKONOS image will be provided to KOMPSAT-2 project for agricultural application.

삼면이 바다인 우리나라의 국토환경에서 해양공간정보에 대한 국민들의 수요가 증가하고 다양해짐에 따라, 육상 및 해상의 지리정보는 관련기관, 민간부분 및 일반인에게 확산하여 부가가치를 창출할 수 있는 사회간접자본으로서의 역할이 요구되고 있는 실정이다. 이에 해양수산부는 제2차 국가지리정보체계 기본계획에 입각하여, 21세기 디지털 해양건설의 초석을 마련하기 위하여 해양지리정보 사업을 추진하고 있다. 본 연구에서는 해양지리정보체계(MGIS: Marine Geographic Information System)사업의 일환으로 해양기본지리정보에 관한 연구를 통하여 해양기본지리정보의 구축 시 필요한 필수항목으로 도출되었던 항목을 기준으로 데이터 모델링 및 데이터구축지침서를 작성하였다. 또한, 향후 NGIS의 통합을 고려한 국가차원의 해양기본지리정보 구성(안)을 제시하였으며 데이터의 품질기준, 유지관리를 위한 방안을 마련하였다.

The distributional characteristics about 8 syntaxa of mantle communitly (Mantelgesellschaften) in South Korea was studied. This study was carried out by geographic and bioclimatic analysis on 326 phytosociological releves on the basis of syntaxonomy and hierarchical system of mantle community already obtained from Zurich-Montpellier School's method, which involves direct analysis on the latitude, altitude, annual mean temperature and the lowest temperature of each site. The distributional characteristics of mantle communities in South Korea appeared from South to North in the order of Mallotetum japonicae, Clerodendretum trichotomae, Akebietum quinatae, Lonicero-Puerarietum lobatae, Spiraetum salicifoliae. Dioscoreo-Actinidietum argutae, Sorbarietum stellipilae and Tripterygietum regelii. It is suggested that the information (syntaxonomical, floral, geographic and bioclimatic data) of Japan, North Korea and China is essential to determine the distributional characteristics of mantle community in Korean Peninsula.

The traditional method to construct Geographic Information System (GIS) is to scan the published maps, then the important and difficult step is to digitize the maps data. It costs a lot of time and human resource. Because a Global Positioning System (GPS) can offer high accurate digital signal directly, we developed a new method that uses the GPS to construct the GIS.

We live in an age of information and an era of rising environmental awareness. As a result, efficient and judicious use of environmental information has become a prerequisite to planning and management of environmental affairs in contemporary societies. So, we have embarked on a study of Environmental Information System(EIS). In the first article, we discussed the status analysis of EIS in Korea, USA, and Japan. This study as the second project has three major components. First, it classifies items and sources of 22 EIA factors. Second, it explains building of environmental information comprising geographic and attribute data of 17 factors. Finally, the study presents applications of EIS as an alternative assessment of suitability analysis. Based on these analysis, the study makes some recommendations and conclusions.

Based on the Chinese resource and environment database, and using the Landsat TM and ETM data acquired in 1990 and 2000 respectively, the spatial-temporal characteristics of land use/cover changes in the Dongting lake area of central China was analyzed. The result showed that cultivated land decreased by 0.57% of total cultivated land. Built -up land and water area expanded, with an increase of 8.97% and 0.43% respectively. 94 percent of the cropland decreased was changed into water (mostly to fishpond) and built-up areas. Land-use changed most quickly in cities, and the slowest in the north and east of the study area.

A geologic hazard map has been produced in the suburbs of Seoul using GIS technology to analyse the degree of geologic hazard, particularly landslides. Topographic, geologic and soil data were incorporated in a map through GIS, which enable to interpret, analyse and predict the regional geologic hazards. Potential elements causing a landslide are slope geometry, geology, groundwater table, soil property, rainfall and vegetation etc. These elements analysed in the study area were input into GIS system through cartographic simulation to produce the regional geologic hazard map. For this work, ARC/INFO(GIS) and ERDAS(IP) system were used.
