Where these data come from
Surfacial representation of discrete one-off events. Methodological comparison based on the example of road accidents in C.U.D.L.

Abstract

Spatial point pattern analysis of large data sets involves powerful visualization techniques. This paper intends to present two suitable methods : the first one is based on kernel density estimation technique, while the second uses regular grid of quadrats superimposed on the event distribution. Both methods are applied to road accidents analysis in the urban community of Lille (France).
