Tracking long-term (1990-2020) deforestation and degradation in tropical moist forests
Product Version: TMF_2020_v1
The European Commission’s Joint Research Centre developed this new dataset on forest cover change in tropical
moist forests (TMF) using 39 years of Landsat time series. The wall-to-wall maps at 0.09 ha resolution (30m)
depict the TMF extent and the related disturbances (deforestation and degradation), and post-deforestation
recovery (or forest regrowth) through two complementary thematic layers: a transition map and an annual change
collection over the period 1990-2020. Each disturbance (deforestation or degradation) is characterized by its
timing and intensity. Deforestation refers to a change in land cover (from forest to non-forested land) when
degradation refers to a temporary disturbance in a forest remaining forested such as selective logging, fires
and unusual weather events (hurricanes, droughts, blowdown).
Release of the new TMF version with the data of year 2020
Any pixel of the map can be queried to obtain the locations (latitude, longitude), the class values
for each available spatial layer and the temporal profile charts with the annual number of valid
Landsat observations and detected disruption observations (absence of tree foliage cover within a
Landsat pixel for a single-date observation).
