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.

DRASTIC system developed by U.S.EPA, is widely used for assessing regional groundwater pollution susceptibility by using hydrogeological factors such as depth to water, net recharge, aquifer media, soil media, topography, vadose zone media, hydraulic conductivity. The system can be applied to site selection of well or waste disposal and landuse for groundwater protection. In this study, hydrogeological spatial database of Younggwang area about topography, drainage, well, geology, soil and landuse was constructed using GIS (Geographic Information System) and regional groundwater pollution susceptibility is analyzed using the spatial database and GIS overlay technique.

환경부에서 시행하는 수질오염총량관리제도를 효과적으로 운영하기 위해서는 하천기초자료들과 함께 오염원 자료가 필요하다. 현재 오염원 자료는 체계화되어 있지 않으므로 필요할 때마다 여러 자료에서 뽑아 쓰고 있다. 따라서 GIS를 이용하여 데이터베이스화하여 물수지 모형 및 수질모형의 입력자료와 연계하여 유역의 오염부하량을 산정하도록 할 필요가 있다. 본 연구에서는 영산강유역을 대상지역으로 GIS를 이용하여 각 오염원에 대한 자료 데이터베이스를 구축하였다. 오염원 자료들을 행정구역별, 오염총량관리유역별로 DB를 구축한 후 이를 이용하여 발생부하량을 산정하였으며, 그 결과를 광주광역시 및 전라남도 영산강 오염총량관리 기본계획 보고서의 발생부하량값과 비교하였다. 두 값의 상대오차를 계산한 결과 $0.003{\sim}4.273%$ 정도로써 계산 결과의 차이가 많지 않았다. 발생부하량 산정결과 생활계와 토지계 발생부하량은 영본B에서 가장 높은 값을 보였으며 축산계 발생부하량은 영본E에서 가장 높은 값을 나타내었다. 생활계, 축산계, 토지계발생부하량 합산결과 생활계와 토지계에서 가장 높은 값을 보인 단위유역은 영본B 지역과 축산계에서 가장 높은 값을 나타낸 영본E로서 수질오염 위험지역으로 분석되어 수질관리를 위한 정화시설 및 저류지 조성이 필요할 것으로 판단할 수 있다. 본 연구의 결과를 이용하여 미래 오염부하량을 예측하는데 활용할 수 있을 것이고 물수지 분석을 위한 모델의 입력자료로 활용 가능하며, 하천의 유역관리 및 영산강유역의 오염총량관리를 위한 기초자료로서 이용될 수 있을 것으로 기대된다.

GIS is a powerful toolbox in managing spatial data associated with attribute data. However GIS is short of spatial analysis function and graphic user interface(GUI) function in dealing with dynamic planning problems. Decision Support Systems(DSS) make up for the shortage of GIS by providing GUI function, modeling function and database function. Spatial Decision Support Systems(SDSS), a new kind of DSS, incorporate display function, basic spatial analysis function and manipulation function of spatial data and attribute data of GIS and GUI function, modeling function and database function of DSS in dealing with spatial planning problems. Planning Support Systems(PSS) add more advanced spatial analysis function and intertemporal function to the functions of SDSS. This study focuses on the modeling of a PSS for capacity expansion of water-distribution network depending upon land use planning by using GIS, value engineering(VE) and life cycle costing(LCC). The PSS shows a guideline about the investment of water-distribution networks related to urban growth management through generating certain numbers of dynamic alternatives to supply the amount of water caused by land use planning.

Population distribution in urban space varies with transportation flow changing along time of day. Transportation flow is directly affected by the activities of urbanites and the distribution of related facilities, since the flow is the result of moving to the point where the facilities associated with their activities are located. It is thus necessary to analyze the spatio-temporal characteristics of the urban population distribution by integrating the distribution of activity spaces related to the daily life of urbanites and the flow of transportation. The purpose of this study is to analyze the population distribution in urban space with daily and weekly time bases using the building database and T-card database in the city of Seoul, which is rich in information on land use and transportation flow. For a time-based analysis that is difficult to grasp by general statistical techniques, a four-dimensional visualization method combining time and space using a Java program is devised. Dynamic visualization in the four-dimensional space and time allows intuitive analysis and makes it possible to understand more effectively the spatio-temporal characteristics of population distribution. For this purpose, buildings are classified into three activity groups: residential, working, and commercial according to their purpose, and the number of passengers traveling to and from each stop site of bus and subway networks in the T-card database for one week is calculated in one-minute increments, Visualizing these and integrating transportation and land use, we analyze spatio-temporal characteristics of the population distribution in Seoul. As a result, it is found that the population distribution of Seoul displays distinct spatio-temporal characteristics according to land use. In particular, there is a clear difference in the population distribution pattern along the time axis according to the mixed aspects of working, commercial, and residential activities. The results of this study can be very useful for transportation and location planning of city facilities.

The purpose of this study is to analyze the spatial relationship between the landslides occurred by typhoon, Rusa in 2002 and geospatial dataset. Landslide locations were detected using satellite image and field survey. Topogra-phy, soil, forest, geology and land use data sets were constructed as a spatial database in GIS. From the database, slope, aspect, curvature, water system, type of topography, texture, material, drainage, effective thickness of soil, type, age, diameter, density of wood, lithology, lineament of geology, land use and lineament were used as the land-slide occurrence factors. Using a frequence ratio model, the spatial relationships between the landslides and the factors were extracted. The spatial relationships is helpful to explain the characteristics of the landslide, and to make landslide susceptibility map.

The purpose of this study is to make and validate landslide susceptibility map using artificial neural network and GIS in Kangneung area. For this, topography, soil, forest, geology and land cover data sets were constructed as a spatial database in GIS. From the database, slope, aspect, curvature, water system, topographic type, soil texture, soil material, soil drainage, soil effective thickness, wood type, wood age, wood diameter, forest density, lithology, land cover, and lineament were used as the landslide occurrence factors. The weight of the each factor was calculated, and applied to make landslide susceptibility maps using artificial neural network. Then the maps were validated using rate curve method which can predict qualitatively the landslide occurrence. The landslide susceptibility map can be used to reduce associated hazards, and to plan land use and construction as basic data.

This study proposes a framework of a GIS service network to connect local governments'Land Management Information Systems(LMIS) together. Databases constructed far LMIS's are very crucial information on both administrative business and civil affairs administration. However, they did not give full play to their values because they could not be shared sufficiently. Local governments build their databases individually using diverse GIS solutions. It causes some problems on sharing them. To demonstrate their geniuses, they should be connected to each other within a network for the whole country, and are served whenever and wherever to people who require them. for this, there are two main problems to be solved. Firstly, a GIS service network that handles heterogeneous and distributed computing environments is organized to link every LMIS each other by the GIS service network vertically and horizontally. Secondly, a mechanism should be developed to access the GIS service network readily and to search GIS data efficiently. The needs from every types of user should be satisfied by the mechanism. As the result of investigation of the issues, one of the most possible solution was suggested in this study, which is a Web based approach. To take into account the advance of information technology in the future and the requirements of e-government, stepwise strategies that integrate the LMIS's into a Web based system was recommended.

도시 계획의 중요성이 부각되면서 다양한 도시 통합 모델의 개발이 이루어져왔으나 기존 모델들은 거시적 측면의 토지이용의 변화만 다루는 한계점이 있다. 본 논문은 토지이용 변화뿐만 아니라 다양한 사회 경제 지표를 반영하여 미시적인 분석이 가능한 UrbanSim 모델을 사용하여 사례연구를 통한 국내 도입 가능성과 시사점을 도출하고자 하였다. 이를 위해 수치지적도, 건축물 대장, 개별 공시지가 등 다양한 시공간 데이터를 이용하여 $150{\times}150m$ 그리드 셀 기반의 입력 데이터베이스를 구축하고 UrbanSim의 Land Price Model에 적용하였다. 향후 보다 현실적인 모델 수행을 위한 다중 스케일 및 Synthetic 데이터 구축 방안과 접근성 측면의 교통 통합 모델로 확장이 요구된다.

급격한 도시화로 인하여 도시기반시설의 필요성에 의해 도시계획시설들이 많이 결정되었다. 헌법재판소는 도시계획시설의 지정으로 인한, 토지소유자의 토지 사적 이용권의 배제에 대해 헌법 불합치 판정을 내렸고, 2000년 1월 28일 도시계획법의 개정이 이루어짐으로써, 기존의 미집행 시설로 인한 사유권의 침해는 시급하게 해결되어야 할 과제로 발전하게 되었다. 이에 따라 장기미집행 도시계획시설에 대한 전면적인 재검토 및 재정비 계획을 수립하게 되었다. 이를 위해 본 연구에서는 GIS 분석기법을 이용하여 미집행 도시계획시설의 데이터베이스를 구축하였으며, 향후 LMIS의 지리정보 전산화일과, UPIS의 도시계획시설 데이터, 조서 자료 및 고시자료 등을 이용하여 미집행 도시계획시설 관리를 위한 기본 DB를 구축하고자 한다.
