Modeling Urban Growth and Form with Spatial Entropy

Complexity, 2020
Entropy is one of the physical bases for the fractal dimension definition, and the generalized fractal dimension was defined by Renyi entropy. Using the fractal dimension, we can describe urban growth and form and characterize spatial complexity.

Understanding the Fractal Dimensions of Urban Forms through Spatial Entropy

Entropy, 2017
The spatial patterns and processes of cities can be described with various entropy functions. However, spatial entropy always depends on the scale of measurement, and it is difficult to find a characteristic value for it.
