This repository contains scripts to reproduce the findings in our paper. The workflow spans two programming platforms, namely Google Earth Engine (GEE) JavaScript API and RStudio. GEE is used to extract data on global LULC maps and spatial context, while R is used for statistical analyziz and data viz.

The ./DATA/ repository does not have the full dataset stored on GitHub due to file size limitations. Therefore you have to re-run the initial scripts to generate the data yourself before you can run the R vizualisation scripts.

The file paths in the R scripts are relative file paths and should be stable to use as is. But please rename file paths in the JavaScript code which are currently hardcoded to a demo GEE Asset. You need to generate data within your own GEE Assets. The data in the GEE assets referenced in the code are shared publicly but we cannot assure their stability over time and they may be deleted.

The workflow is as follows:
