A GIS is developed for the effective use of information for earthquake disaster mitigation. Data structures on information of disaster mitigation including fault data, soil data, and building data are analyzed using object-oriented approach. The dependency and spatial relationship among data sets are clarified, and databases are established. The GIS is designed as an integration system of a map system, data analysis systems and a wave analysis system. The GIS is implemented using X-Window and the application to earthquake disaster mitigation for Nagoya, Japan is presented.

This paper proposes a decision-making support system for child care facilities using GIS. In this system, first, a user fixes parameters concerning the behavior of working mothers, that is, their trips to office. Child care facilities are treated as intermediate points on their trips. Next, the user chooses an improved plan for child care facilities, and the system evaluates the plan on three viewpoints. If the result is not satisfactory, the user chooses another alternative. Such a choice-evaluation process can be repeated interactively with ease because of a user-friendly graphical interface. Through the repetition of this process, a policy maker approaches the best alternative. In addition to this function, the system suggests a desirable location of a new facility. This helps the user to reach a better alternative. In the empirical study in Setagaya, several plans for an improvement of child care facilities are evaluated and compared.

The National Rural Development Committee of Thailand has been conducting regular village surveys covering about 60, 000 villages in rural areas across the country. The first trial survey was conducted in 1982, and the survey was expanded to the whole kingdom in 1986. Since the 1986 survey, the results have been input into a village database, which is available for distribution. The survey covers many topics related to the socio-economic situation such as the infrastructure, the production environment, education, hygiene and so on. I have been developing a Northeast Thailand Village Information System (NETVIS) with a view to using the village database to identify the transformation of rural areas of Northeast Thailand. If detailed information on national geographic coordinates, climatic data, and soil data can be incorporated, I believe that the NETVIS can be developed into an integrated system.

The aim of this paper is to analyze the service areas of three sport clubs in a Japanese city using GIS. Figure 2 is colored in the contour map constructed on the basis of the number of members per square kilometer for each sport club. To analyze the inner structure of the service area, Figure 3 represents 3-D surface of service area using TIN of ARC/INFO, on which 2 km, 4 km, and 6 km circles are overlaid centering around each sport club. Table 2 shows the composition ratio of the number of members within each circle. To analyze the penetration into market by three sport clubs, the market penetration ratios for women aged twenties and men aged thirties are calculated and overlaid on their population surfaces as shown in Figure 4.

Urban utility companies, which supply customers with gas through underground facilities in metropolitan area, have had an urgent need for quick emergency action and restoration system in earthquake. The Tokyo Gas had completed establishment of GIS data base of 28, 000 mains and services from 1983 to 1990. This paper describes utilization of GIS in order to stop gas supply quickly in isolated areas at the time of earthquake and restore underground facilities as soon as possible.

Following to the past research about the concerning level of GIS for local governments, we discussed the problems of unfamiliar for GIS. As a result, the further research was collecting the GIS specifications from local governments already introduced. The 22 of 33 selected local governments were sending the papers. Viewpoints of this analysis were, 1. Recommended field for GIS application, 2. The data model of GIS, 3. CB analysis of GIS, and 4. Organization and training. The status of analysis was ongoing, and we will publish next year by many discussions of local government persons.
