Explore Distance-decay Relationship with Python
Modern geographers and urban planners frequently utilise spatial analysis to understand how human activities and land uses are dispersed across the landscape. One of the fundamental concepts at the heart of these studies is the distance-decay relationship. Distance-decay models describe how the interaction or influence between two points decreases as the distance between them increases. These models have a wide range of applications, and they are invaluable tools in understanding and predicting spatial patterns and interactions in the geospatial industry.
Python is a powerful tool to do distance-decay analyses. In this article, we will be using Python to analyse the relationship between Queensland’s residential areas and other land uses, in order to uncover intriguing spatial patterns and insights.
