Anais do XX Simpósio Brasileiro de Sensoriamento Remoto

PRODES and DETER, Brazilian programs to monitor
deforestation, rely on free optical images for visual
interpretation, which can be obtained from the sensors
on-board several satellites, such as Landsat-8, Landsat-9,
Sentinel-2, CBERS-4, CBERS-4A and Amazonia-1. However,
in optical remote sensing images, clouds and cloud shadows
have a direct impact on the number of Earth’s surface
observations. Combining images from different sources can
help to overcome this information gap. Based on that, the
Brazil Data Cube started to produce an experimental product
that combines CBERS-4 and CBERS-4A images from the
WFI sensor on-board both satellites. The main idea of this
product is to provide spatial and temporal mosaics with less
clouds and cloud shadows than products containing images
from a single satellite, improving visual interpretation.
