GIS-based noise spatial analysis
The core of spatial analysis is to understand the spatial dependence and spatial association of some data related to geographic location, and to establish the statistical relation among the data according to the spatial location. Base on the knowledge of spatial analysis and fifty on-site measured noise value, this paper analyzes the noise date distribution the central area of Guangzhou city a by GIS spatial analysis software Geoda. It shows that the spatial analysis could offer some reference for analyzing spatial structure and pattern of environmental noise and for policy ? making related to noise issues.
