Lorenzo, if your project aims to track deforestation in a timespan, IMHO you had better to focus on trees only. Trying to guess which landuse is going to replace trees is hard. I'd start from an AOI entirely mapped with forest, wood or, in doubt, the generic landcover=trees all of which derived

adding top-level categories to the landcover value is maybe the best idea, it allow incremential mapping : - you 'll add true value depending of your "level" and the quality of the source - another day another mapper may improve it. Le 14.03.19 à 22:33, Lorenzo Stucchi a écrit : > Hi all, > >
