Abstract:
The evaluation of the spatial similarity of two observed point patterns is an important issue in spatial data quality assessment. In this work we propose a formal procedure that takes advantage of the joint use of space-filling curves and the multinomial model in order to establish a statistical test to compare spatial point patterns. In this mix, the space-filling curves offer a mechanism to order the 2D, 3D or nn-D space and the multinomial distribution the statistical approach for testing homogeneity. A simulation method is proposed in order to analyze the applied performance of this idea.
