From the perspective of client-oriented administration, the study introduces the basic structure of Urban Inormation System (UIS) and examines problems and new strategies of UIS in Korean local governments. The study selects five metropolitan cities for a case study. According to this case study, UIS in Korea are focused on AM/FM and internally used only by practitioners. No government surveyed what their citizens want to get from UIS. To solve these problems, the study proposes developing strategies for client-oriented UIS as follows. First, local governments could use policy delphi technique to sum up the citizens' needs on UIS. Second, they need to pay more attention to the diversity and transmutability of administration zone and consider the importance of the connection between administration zone and attribute data collected on them. Third, UIS needs to keep a balance between AM/FM and living GIS. Fourth, internet UIS needs to be constructed which enables citizens' access to UIS more easily. Finally, GIS education and client-oriented administrative education need to be combined to improve government employees' mind for UIS.

With the rapid development of information and telecommunication technologies, the adoption of ubiquitous technologies is increasing for the realization of new effective u-City services. u-City is defined as a next-generation informatization city that can innovate a city's various functions, such as improving the welfare of the citizenry, ensuring safety based on systematic urban management, improving the quality of lives, and increasing convenience in city life, by merging cuttingedge information and telecommunication infrastructures and ubiquitous information services with urban space. There is therefore a need to recognize that a successful u-City implementation strategy involves developing the previous UIS into a ubiquitous technology-based UIS and integrating UIS's various urban informations with effective u-City services. In this paper, for UIS-based u-City implementation, the intelligent integration model of urban spatial information based on interoperability is proposed.

Recently, urban information system(UIS) has been developed and utilized by local governments in Korea and has become a key means of urban informatization of local governments. When UIS is conducted only for FM oriented internal utilization regardless of its cost-efficiency, however, its cost-benefit structure could be distorted seriously. The study utilizes benefit cost analysis technique and applied the technique to a model case of Chungju UIS selected by National GIS team. Chungju City developed its GIS for the management of roads and urban planning in 1993. At its beginning, the system was an efficient model with relatively strong cost-benefit structure and could produce positive net benefit 10 years' after its construction. When the city began to develop its facility management with the financial assistance from central government in 1998, however, its cost-benefit structure became distorted. As a result, it is delayed for the UIS to produce positive net benefit until the year of 2015. Using benefit cost ratio, discount rate and Mobile GIS, the study also conducts a sensitivity analysis.

지방자치단체 업무를 지원하기 위해 구축된 지리정보 활용 시스템을 UIS (Urban Information System : 도시정보시스템)라 한다. 본 논문은 각 지방자치단체가 많은 비용을 투자하여 개발한 UIS 활용을 극대화하기 위해 지방자치단체의 현장업무 중심의 UIS에 GPS와 PDA을 결합한 LBS(Location-Based Service:위치기반서비스) 시스템을 제시한다. 본 연구에서 제시된 시스템을 개발하여 활용한다면 현재 UIS의 가장 큰 문제점인 데이터베이스 유지보수 비용을 절감할 것이라 기대된다.

Recently, natural disasters like flooding damages have frequently occurred as to typhoons and local downpours affected by the climate changes. Many researches have actively been studied in analysing runoff models, the verification of their parameters, and the inflow on surfaces in order to lessen the damages. However, much time and effort needs in generating input files of the models in most current researches. Therefore, in this paper we develop a system for generating a simulation input data automatically. This system is connected to the EPA-SWMM based on the spatial data in the UIS systems and consists the simulation module for analysing urban flooding and the SWMM simulator module. Also, we construct a prototype using a range of regular inundation to generate a simulation input file. This system gives advantages showing inundation areas based on the map viewer as well as lessening errors of input data and simulation time.

Some local governments in Korea are currently developing various Urban Information Systems (UIS) to computerize their work. But they have spent too much money on their own UIS development because they have not reused the existing UIS of others. It has caused the central government to invest money repeatedly. The work of some local governments is generally very similar to those of others. The purpose of this paper is to suggest a solution to the reinvestment problem. To solve the problem, this paper suggests that they could model a city's business using Unified Modeling Language and Component-Based Development Process (CBD). They could also develop a UIS from the existing models, and then other municipalities can reuse the developed UIS. This paper illustrates the water supply business of P City in Korea and Rational Unified Process as a CBD. This paper also describes methods to apply CBD, to establish a reusable business model, analysis model, and design model, and to develop the software components of ActiveX Controls form for the water supply business.

It is essential to build a high quality database in developing a UIS to enhance the administrative effectiveness of municipal governments. To secure such a high quality DB, a proper methodology of quality control should be established. It is imperative to have such a method fit UIS DB considering that the conventional method has mainly been focusing on the quality control of the digital layers itself. Therefore, this study have analyzed the city of Inchon's UIS DB to devise a proper method to categorize the types of errors and to identify major relevant items. Also, the magnitude and frequency of each error along with its major cause have been analyzed to propose a quality control procedure to minimize the errors

The history of GIS in Japan have been started from the Mesh-data at 1969 and the UIS (Urban Information System) at the early 1970's, and recently we can find the tenn of GIS in many fields and places in Japan. Specially after the Earthquake disaster of Kobe, the importance of the Emergency Management System and the Spatial Data Framework have been growing quickly and the studies and projects of GIS have been increased more and more. I hope that the study about the history and the recent situation of GIS in Japan can show the right way for many GIS projects in our country and so we can be escaped from the amusement of time and money, because the land Regulation System and the Concept of Land Ownership of Japan are very similar to those of Korea. For that purpose, first, I try to trace the history and the present situation of GIS, UIS, FM/AM and Spatial Database Framework in Japan, second, to identify the advantages and disadvantages and problems of Japanese system and finally to suggest more propper way for the GIS projects in Korea.

The aim of this study is propriety review for underground facility surveying on development area of land for housing and efficient management. Because of integration information administration system construction of the nation and development of information technology, construction of Urban information system(UIS) to manage systematically city space is increasingly necessary We manage systematically attribute information for each lot in the development area of land lot housing that it Is connected with NGIS in order to drive gradual computerization of underground facilities and arrange the base of facility management. Review arrangement methods on development area of land for housing makes it to check safety accident of urban and to leading base of urban information. Thus, this study draw the most suitable way through analysis of driving methods and expectation effect from above facts.

The goal of this paper is to calculate flood elevation by applying temporal distribution of rainfall through HEC-RAS(Hydrologic Engineering Center's River Analysis System) and to automatically create areas of flooding by a user-defined spatial model based on GIS using calculated values of flood elevation and detailed data of topography. Accuracy of topographic data is the most important factor because of deeply changing analysis results of flooding areas of a river. Therefore, this paper suggests a method of attributive and spatial data construction based on the GIS using UIS(Urban Information System, river-related reports, and hydrologic information. Also, we implement an expression system to provide analysis results extracted from the proposed model.
