Hi, a. If the object of the research is just to map deforestation, you only need to map trees. You also need 100% coverage of all tree areas. You do not need to map "no landcover". b. If the object is to map deforestation AND what replaces the trees, you need to map the replacing landcovers

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
