The loaded dataset in Zenodo includes six parts: (1) Shp file of the Congo Basin; (2) Shp file of the validation points for evergreen forest cover map in 2000 (reference value '1' means forest, and '0' means non-forest); (3) Shp file of the validation points for the forest loss and non-loss during 2001-2020, and it also includes the forest loss year (reference value '1' means forest loss, and '0' means non-loss; loss_year values of '1,2, ..., 20' mean the year of '2001, 2002, ..., 2020'); (4) GeoTIFF image of the evergreen forest cover map in the Congo Basin (file name 'Congo_EvergreenForestCoverMap_2000'); (5) GeoTIFF image of the annual forest loss map generated by Hansen's Global Forest Change product [1] (file name 'Congo_Hansen_GFC_annualForestLoss_2001to2020'); (6) GeoTIFF image of the annual forest loss map produced by the proposed method in the Science Advances paper (file name 'Congo_Proposed_annualForestLoss_2001to2020').
