Supplementary information for Coralita mapping (Report) publication (BioNews Article).
Supplementary Text In the Material and Methods section of the main text, we provide an overview of the classification procedure using a Support Vector Machine (SVM). In this Supplementary text, we provide further details regarding the following components of the procedure: i) the radiometric and atmospheric correction of the WorldView-2 image (part of Step 0 in the main text); ii) the selection of the 10 independent, most-explaining variables to be considered within the SVM classification (part of Step 2 in the main text); iii) Cross-validation to evaluate SVM model performance iv) the post-processing steps that were performed after obtaining a Coralita distribution map from the SVM procedure (also part of Step 2 in the main text).
