Although the frequency of use for community facilities in rural villages is growing as well as the importance of the facilities for urban-rural exchange is being highlighted, study on spatial location-analysis of the facilities for such multi-purpose is not so much. This study aims to find the spatial distribution forms of community facilities in rural villages such as community center and rural-pocket park through location-analysis, in order to provide available data for selecting location in the future. As the study area, Sojeong-myeon, Sejong Special City was selected. This study conducted GIS analysis for criteria of the location-evaluation model developed in this study. This study introduced the concept of time-distance for accessibility analysis. This paper also used linear-consecutive scoring method(LCSM) as a scoring method of criteria and Analytic Hierarchy Process(AHP) method for weighting values of criteria. The application results showed that the new model can generate the intensity of community facilities according to spatial distribution and accessibility from cities to the facilities.

The purpose of this study is to derive policy implications in allocating day care centers for the elderly with more efficiency and/or equity by calculating and analysing the accessibility scores of individual dongs to day care centers for the elderly in Seoul using GIS spatial analysis techniques. The study finds that the spatial distribution of the centers does not respond to the distribution of the potential users very well and that dongs in Gangseo-gu and Songpa-gu at the outskirt of Seoul has the lowest level of accessibility. The findings of the study has policy implications in the management of day care centers for the elderly. First, in order to improve the accessibility of the elderly to the centers, an increase in the number and the capacity of the centers needs to be made especially in areas with lower level of services provided. Second, if policy decision is made in the way to increase the capacity of the existing centers rather than to increase the number of centers due to, for example, the budget limit, capacity expansion needs to be made in the centers with higher proximity in order for more elderly people to use the centers more frequently with easy access. Finally, this type of accessibility analysis techniques needs to be used to allocate, expand, and evaluate other types of care facilities for the elderly and social welfare facilities in order to preserve the welfare right of the users of the facility who usually have a lower mobility and to assure the necessity of the resource investment.

Flood inundation analysis system using GIS has been developed to simulate inundation in airport drainage areas. The model developed in this study has been synthetically presented and constructed the preprocess for database construction and input data preparing through a graphic user interface, GUI system and the postprocess processing graphically output resulted in mainprocess analysis model linked GIS(ArcView/Avenue). The mainprocess analysis model was simulated in real phenomenon caused by inflow of storm sewer system by simulation flooding due to backwater effect and surcharged flow in storm sewer system by simulating interaction coupling the overland flow analysis model and storm sewer system analysis model. In the future, the flood inundation analysis system developed in this study will be a great contribution to systematic decision-making for establishing the flood-mitigation management and facilities improvement plan to flooding damage in airport.

NGIS project was carried out to accelerate Korea to an information-oriented land. NGIS Project also is to support training projects for GIS specialists as a sub-project. This program has two categories which are long-term courses and short-courses. The long-term courses are for people who want to get a job in SIS(Spatial Information System) field and also for public services personnel who want to acquire the latest SIS technology. Short-term courses are about the latest GIS component technology and utilization spatial data. In this paper, we analyze education programs and training courses relate to SIS. Also we suggest some directions to train specialists for the effective achievement of SIS project. To efficient education for SIS specialist, education programs have courses without repetition and courses are separated by technology type.

By the progress of Information Technology, spatial data have been recognizes as one of essential infrastructure. Now for the near future needs of urban simulation, management, u-City construction, etc. MOCT(Ministry Of Construction & Transportation) have been driving to construct the 3D Geo-spatial Data as one of National Spatial Data Information on a base of 2D GIS(Geographic Information System). In this study we tried to analysis the demands and the optimum implementation method of 3D Geo-spatial Data in local governments. As the result of study, the plan to utilize 3D Geo-spatial Data and to carry out its utilization, and the advanced vision of 3D GIS in for the public affairs of Local Governments and private business scope were proposed.

Urban space structure tends to have a significant change in accordance with maintenance of urban infrastructure such as a traffic route. For this reason, quantitative analysis has been needed to establish spatial distribution and location patterns by considering change of both road accessibility and urban infrastructure level, which can have the most pervasive influence in urban development process. Therefore, this paper aims to analyze spatio-temporal urban morphology through considering distribution patterns of road among transportation infrastructures, population, and spatial structure of metropolitan areas, focusing on Seoul where population growth and the size of urban area have been dramatically increased. For this, we firstly developed and constructed time-series GIS database by using satellite images and topographic maps of the last 70 years to analyze variables which affect urban growth and transportation. In particular, we analyzed the transform of the system of the street by Space Syntax which is able to grasp hierarchical spatial structure through visibility of space and spatial cognition in terms of accessibility. What's more, we analyzed and visualized the relationship urban morphology and road according the regions of Seoul through IPA(Importance Performance Analysis). In terms of the integration land-use and transportation, Space Syntax approach is expected to contribute to efficient urban planning through understanding the influence which various transportation phenomena has an effect on urban development patterns.

The systematic data management system in the area of river flow analysis has not yet constructed, even though the need is evident due to the complicated process of tremendous input/output data in the modeling study and the importance of visualization of spatial flow variation. The objectives of this study are to suggest the method for constructing the NGIS-based river database based on contour, river, elevation, boundary layers and river cross sections and to provide the algorithm for interpolating equi-distance river cross section points. The selected study area is the main Han River starting from Paldang dam site to Indogyo bridge. The constructed database will be useful for the scientific water flow management system in the study area.

Erosion and landslide cause serious damage to forest areas. As a consequence, partial or complete destruction of vegetation occurs, which leads to many cascading problems. In this study, an attempt has been made to identify the forest areas, which are under different risk categories of erosion and landslide, in part of Eastern Ghats of Tamil Nadu. Relevantthematic maps were generated from satellite data, topographical maps, primary and secondary data and weights to each map were assigned appropriately. Weighted overlay analysis was carried out to identify the erosionprone forest areas. The result of erosion and landslide prone model reveals that 4712 ha(17%) of forest area is under high risk category and 15879 ha(58.65%) isunder medium risk category. The results of spatial modeling would be very much useful to the forest officials and conservationist to plan for effective conservation.
