Mangrove area data for the Mekong countries are extracted from global mangrove area data by Bunting, P et al. This data used the L-band Synthetic Aperture Radar (SAR) global dataset from the Japan Aerospace Exploration Agency (JAXA) from 1996 to 2020. The study used a follow-up approach. map-image approach for change detection where the base map (GMW version 2.5) is updated using contextual mangrove change thresholds and masks. This approach was applied between all date-image pairs producing 10 maps per epoch, summed up to generate a global mangrove time series. The obtained mangrove coverage maps have an estimated accuracy of 87.4% (95th conf. int.: 86.2 - 88.6%), although the accuracy of the layers is variable and individual losses were lower at 58.1% (52.4 - 63.9 %) and 60.6 %. (56.1 - 64.8%).
