Extension of Spatial Correlation Analysis to Road Network Spaces
The spatial correlation analysis is proposed to analyze urban activities quantitatively. This paper describes an extension of spatial correlation analysis defined in a two-dimensional Euclidean space to a roadnetwork space. We discuss a method for applying spatial correlation analysis to a road-network space and illustrate the details of computation methods. By using actual GIS data as numerical examples, a comparison of the results from the Euclidean distance and the network distance is shown. Also, we demonstrate some case studies using a variety of computation methods.
