Abstract

This paper summarized calculations of urban morphological characteristics for about 11 km2 area of Chiyoda-ku. A three-dimensional building data and urban terrain data were integrated and analyzed using a geographic information system. Some parameters describing the urban morphology that were calculated include the frontal area index, building plan area fraction, building area density, mean building height, variance of building height, aerodynamic roughness length and zero-plane displacement height. The results were then compared to the value of another parameter by correlation analysis. From these results, possibility of application was considered as index for optimal design method for building arrangement considering wind environment.[This abstract is not included in the PDF]
