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. View Full-Text
