Spatial Tessellations: Concepts and Applications of Voronoi Diagrams
TL;DR: In this article, the Voronoi diagram generalizations of the Voroni diagram algorithm for computing poisson Voroni diagrams are defined and basic properties of the generalization of Voroni's algorithm are discussed.
Journal ArticleDOI
A kernel density estimation method for networks, its computational method and a GIS-based tool
TL;DR: A ‘natural’ extension of the univariate kernel method to density estimation on a network is formulated, and it is proved that its estimator is biased; in particular, it overestimates the densities around nodes.
Book ChapterDOI
Point pattern analysis
TL;DR: In this paper, measures of Dispersion Quadrat Analysis (MDA) and Dispersion Distance Methods Methods of Arrangements (MDF) are presented. But they do not consider the relationship between the distance and the dispersion distance.
Book

Atsuyuki Okabe,Kokichi Sugihara +1 more
TL;DR: Spatial Analysis Along Networks provides a practical guide to the necessary statistical techniques and their computational implementation, from Stochastic Point Processes on a Network and Network Voronoi Diagrams, to Network K-function and Point Density Estimation Methods, and the Network Huff Model.
