The thresholds are 30 cm (`Peat30.tif`), 40 cm (`Peat40.tif`), 50 cm (`Peat50.tif`) and 100 cm (`Peat100.tif`). Depending on peatland definition, testing with a hold-out dataset indicated Accuracy of 0.89 –⁠0.91 and Matthew’s correlation coefficient of 0.79 –⁠0.81. The final maps show a national forest peatland extent of 60,292 – 71,996 km², estimates which are in range with previous studies employing traditional soil maps. #### Version history ##### Version 2 Data files and peatland extent updated and list of creators re-ordered. - Gotland and Öland were removed from the maps, following conclusions drawn in the review of Rimondini et al. (2023). ##### Version 1 Initial release
