The files are organised in the same sequence in which they were applied throughout the study, allowing the complete reproduction of the analytical workflow, from the statistical analysis of limnological data to the generation of spatial distribution maps using Sentinel-2 imagery. All statistical analyses were developed and executed using R version 4.5.2.
