Abstract
The purposes of this paper are: to propose the network Voronoi cross K function(NVCKF)methods which analyze the distribution of points in relations to points, lines and polygons on network Voronoi areas; and to develop a GIS-based tool for performing thesemethods. First, the paper explains the planar Voronoi cross K function(PVCKF)method which analyzes the points in relations to points on planar Voronoi areas. Second, the paper formulates the point NVCKF method and the line NVCFK method by extending the PVCKF method to a network. Third, the paper implements these computation methods as a GIS-basedtool. Last, the paper tests applicability of the proposed methods to actual data analysis usingthe tool.
