Fractal point processes: a reverse box-counting method

Fractal dimension is useful to characterize the structure of spatial objects such as urban structures or river networks. However, fractal analysis is underutilized for point processes. In addition, the fractal geometry is mainly used to analyse shapes than to create them. This seminar aims to suggest a method to generate fractal point processes. The procedure is a reverse box-counting method that is quite efficient since the relative error between the theoretical and produced fractal dimensions do not exceed 2% when the structure of the object is quite small. Beyond its goal to create point processes, this method is also a way to explore the relationship between the fractal dimension and the classical methods of spatial analysis in geography.
