An analysis of accessibility to spaces for disaster refuge considering danger of street-blockades caused by collapse of buildings on evacuation routes

Abstract: The purpose of this study is to evaluate accessibility to spaces for disaster refuge considering danger of street-blockades caused by collapse of buildings on evacuation routes. To this end, a model of street-blockades is developed based on Monte-Carlo simulation of collapse of each building using Tokyo Metropolitan Government GIS in the area around Machiya Station, Arakawa Ku, Tokyo. The situation of street-blockades caused by the collapse is illustrated and accessibility to spaces for disaster refuge is evaluated in terms of possibility, allocation, distances and routes of evacuation.

Effect of spatial scale on urban land-use pattern analysis in different classification systems An empirical study in the CBD of Tokyo

Abstract: Urban land-use pattern occurs not only at certain spatial scale but also at certain classification system. Study of spatial scale effect on urban land-use pattern analysis for construction of spatial model of urban land-use changes entails consideration of urban land-use classification system selected. The objective of this paper is to investigate the effect characteristics of spatial scale on the result of urban land-use pattern analysis for two different classification systems in terms of spatial autocorrelation and fuzzy mathematics by an empirical study in the CBD (Central Business District) of Tokyo so as to provide some useful information for construction of multi-scale or hierarchical spatial model of urban dynamics. The results show that while spatial autocorrelation of all the categories of urban land-use at different classification systems in this study is scale-dependent, characteristics of the spatial scale effect on pattern of urban land-use categories are different for different classification systems. However, the general change trends of spatial autocorrelation of urban land-use for different classification systems show similar across a range of scale. Reducing number of urban land-use categories for one classification system may diminish the loss of information of land-use area across the range of scale and the effect of spatial scale on urban land-use pattern analysis in the certain extent.

A Study on Information Sharing GIS to Accumulate Local Knowledge in Local Communities

Abstract: This study aims to develop an information sharing GIS, specially tailored to the efficient accumulation of regional knowledge within regions on the city, town, and village spatial scale. The information sharing GIS is a geographical information system which integrates a Web-GIS, an SNS (Social Networking Service), and a Wiki into a single system. The information sharing GIS uses a design which ameliorates the following three constraints such as time constraints, spatial constraints and continuous operation related constraints, making it possible to design systems in accordance with target cases. After operating the information sharing GIS to accumulate regional knowledge about security information for about one month in the local communities of Chofu City and Mitaka City in Tokyo, the system was evaluated based on the results of a questionnaire survey to users in order to identify improvements.

An integrated approach to evaluate potential impact of precipitation and land-use change on streamflow in Srepok River Basin

Abstract: To manage water resources effectively at a local level, decision makers need to under- stand how climate change and human activity may impact local streamflow as a precious natural source of water use. However, the impact is often not well studied with locally obtained data such as monitored flow. This paper presents an integrated approach to study potential impact of precipita - tion and land-cover change on local streamflow over the next decades. The study area is the Srepok River basin, a tributary sub-basin of the Mekong River. A hydrological model was developed in the Hydrologic Modeling System (HEC-HMS) environment and calibrated using local precipitation and streamflow data. Several scenarios were developed considering climate change and socio-economic development in a GIS environment, and streamflow in 2025 and 2050 was estimated for each sce- nario. The paper ends with discussion on possible adaptations for a given area.
