AN EXTABLISHMENT OF NAGANO CITY ENVIRONMENTAL GIS DATA BASE AND APPLICATION OF URBAN ENVIRONMENT ANALYSIS(Environmental Engineering)

Abstract

GIS data base system was established with many kinds of statistical data and urban environmental data. The data are able to search, to analyze and exhibitive on map data. Urban environmental map was developed, and it was applied to urban environmental analysis with statistical data. Two types examples were analyzed. The distribution of air temperature difference between day and night was analyzed. The relation between road traffic noise and road traffic volume was analyzed. It was proved that GIS data base system is effective to understand environmental problem in urban area.
