abstract = "Cerrado is the second largest biome in Brazil, covering about 2
million km2. This biome has experienced land use and land cover
changes at high rates due to agricultural expansion so that more
than 50% of its natural vegetation has already been removed.
Therefore, it is crucial to provide technology capable of
controlling and monitoring the Cerrado vegetation suppression in
order to undertake the environmental conservation policies. Within
this context, this work aims to develop a new methodology to
detect deforestation in Cerrado through the combination of two
Deep Learning (DL) architectures, Long Short-Term Memory (LSTM)
and U-Net, and using Landsat and Sentinel image time series. In
our proposed method, the LSTM evaluates the time series in
relation to the time axis to create a deforestation probability
map, which is spatially analyzed by the U-Net algorithm alongside
the terrain slope to produce final deforestation maps. The method
was applied in two different study areas, which better represent
the main deforestation patterns present in Cerrado. The resultant
deforestation maps based on cost-free Sentinel-2 images achieved
high accuracy metrics, peaking at an overall accuracy of 99.81% ±
0.21 and F1-Score of 0.8795 ± 0.1180. In addition, the proposed
method showed strong potential to automate the PRODES project,
which provides the official Cerrado yearly deforestation maps
based on visual interpretatio.",
