Supplementary Information: High spatial resolution mapping identifies habitat characteristics of the invasive vine Antigonon leptopus on St. Eustatius (Lesser Antilles)
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).
