It is possible to evaluate hi-tech spatial services such as U-City services as part of the visible results from more than 10 years of public efforts and budgets on Korea National Digitalization. The U-City services are mainly based on ICT(Information and Communication Technology), but in the aspect of giving intelligence to the existing physical space, in principle, they are to be inter-connected with both spatial information and spatial plan. But, still there are few shared concepts for linking U-City services with spatial information and spatial plan. Therefore, under the proposition of the realization of Ubiquitous National Territory in the Digital Convergence Era, the purpose of the current study is to facilitate the balanced development among U-City services, national spatial data and spatial plan by proposing a new concept of Digital Convergence Space. Then, for its realization, regarding laws and policy arrangements are suggested.

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.

The rebuilding or redevelopment of buildings in the Readjustment Project District is generally built high-rise buildings. It sometimes makes our residential area to be uniform in height and disharmony with surrounding houses and infrastructure. Then this research examines the landscape effects of the height of buildings built using landscape simulation on hillside and level ground. We suggested that it was desirable for a land readjustment project district to be managed by District Plan and Development Density Controlled Area. In addition, a consideration for the introduction of Average Floors is needed to mitigate the uniform and disharmony with surroundings.

The general urban plan is the plane plan which limits general and uniformed constructions; however, the district unit plan is the solid plan that can leads various constructions by discriminating by plot, housing area and lot. Therefore, for the zone plan, not only the two-dimensional plot information such as plot usage plan, but also the three-dimensional plot information needs to be used to analyze lighting, sewerage and directions. To fulfill such requirements, the information can be gathered using GIS and photogrammetric method for the reasonable and efficient zone plan. In this research, the information about the testing area for the zone plan has been gathered using GIS method, and the three-dimensional model about the area has been built using the satellite image and DEM. As the result, plot usage analysis, direction analyst, water system analysis, and slope analysis has been done and used efficiently to build the district unit plan. Also, after the result after applying the analyzed result to the actual area says this is very appropriate and efficient.

본 연구는 연구대상지의 위성영상을 이용하여 물, 산림, 인공구조물, 나대지, 경작지, 초지의 6항목으로 토지피복 분류를 수행하였으며, 인공위성 영상에 나타난 시계열적인 도시피복의 변화 현상을 파악하였다. 이러한 각각의 결과를 통하여 종합적인 도시지역 내의 공간현상을 파악하고자 하였고, 시간의 경과에 따라 각각의 항목별 변화에 대한 통계량을 추출하기 위해 GIS의 GRID 연산을 수행하여 도시 내 공간적인 변화를 분석하였다. 연도별 위성영상을 분석한 결과 체계적인 도심의 모습으로 발전시키는데 중요한 기초자료로 이용될 수 있고, 도시계획 수립 및 개발을 위한 의사결정 자료로 이용할 수 있으며, 도시의 향후 발전 형태를 예측하고 과거자료들을 분석하여 주요지역에 필요한 제반시설물들의 위치를 결정하는데 유용하게 이용될 수 있을 것이다.

Recently, there is a great expectation for the sustainable effect of TOD and apply it to urban planning and design. However, there are few research on the quantitative evaluation method of the effect. The purpose of this study is to propose a quantitative way to assess the effectiveness of TOD(Transit Oriented Development)'s vehicle traffic reduction in the urban planning phase, based on the land-use plan. Firstly, it proposes a method to convert the information contained in the land-use plan into a network and secondly a method to estimate the travel distance based on the network. In the first phase, the roads in the land-use plan are converted into links and the intersection of the roads into nodes. The area and the height of the zones included in the land-use plan are converted into the weights on adjacent nodes. The second phase assumes the frequency at which travel occurs between nodes on the network is relative to the weights and estimates the travel distance by dividing it into a pedestrian and a vehicle. Then, taking the city without TOD as the object, through comparison present city and alternatively redesigned city to the analysis of TOD effect. In this study, the application of these methods to Bundang as of 1997 and alternatively redesigned Bundang showed that about 39.94 percent of the vehicle traffic reduction effects occurred. Furthermore, the pedestrian traffic ratio of alternatively redesigned Bundang increased to 2.39%.

Information can be visualized as information technology and computers have recently made dramatic improvements. Thanks to the brisk effects of providing information in 3D on the web with the technological developments of Web 3D and virtual reality implementation in the Internet, there has been the trend to present geographic information in images and 3D. In this study, the Web 3D GIS technique was adopted in analyzing the current state of urban landscape and examining and predicting the urban landscape affected by new urban development businesses. As a result, it was expected that the study would be able to help the government agencies to reduce their errors in making urban landscape plans and policies and implementing them to provide objective and visual data, and to come up with a simulation system that could be used to reflect the residents opinions in plans and policies.

The objective of this research is to assess the level of urban park service provision in comparison to demand population size by region (e.g., dong) in Busan metropolitan areas. To this end, a park service provision assessment index is utilized. The index is built upon the difference between planned and actual levels of park service provision. For each region, planned level is obtained by multiplying the per capita service amount by the number of residents in that region. Actual level is estimated based on Huff model, where distance between parks and residential locations are explicitly accounted for in model building. Empirical analysis was carried out for Busan Metropolitan Area. The result shows that Gumsung-dong, Chunga-dong and Dongdaesin3-dong are well supplied with park service, while Hadan1-dong, Goejung2-dong and Joorae3-dong are under-provided when per capita service provision amount and the extent of service area are set to $6m^2$ and 1km, respectively. It is argued that those regions that suffer from under-provision need to be highlighted such that a priority is given to those areas for establishing new urban parks when renewing urban management plan.

The purpose of this study is to analyze the growing course of Busan, Gimhae and Jinhae and further find patterns of the urban growth. This study shows that patterns of the urban growth differ from city to city, being influenced by the city's characteristics. Acknowledging this fact would help the decision maker to determine the developing plan of the urban. The methodology for this study is as follows; Fuzzy set concept is applied to minimize the data loss. At the same time, the AHP is used to give a relative weight to each factor. In order to be able to manage the change based on the dynamic model and time, Cellular Automata is introduced to simulate the growth of urban. The results show that the pattern of Gimhae's and Jinhae's growth is the same, whereas that of Busan is different from them. That is to say, each city has regional characteristics. And the pattern of the urban growth is influenced by the regional conditions of the city.
