The Colombian Pacific coast mangrove extent was mapped primarily based on the workflow and semi-automated mangrove mapping methods applied by Shapiro et al. (2018). The analysis structure and methods were further supported and adapted according to approaches applied by Yancho et al. (2020) within the Google Earth Engine Mangrove Mapping Methodology. The mangrove cover extent was obtained by applying a pixel-based supervised classification approach and a Random Forest classifier. The composites derived from a combination of Sentinel-1 and Sentinel-2 images were used as input data for the models. Finally, the results are presented via a simple web map application for better access.
