Sentinel-2 image mosaic of Brazilian Amazon biome with 10m of spatial resolution. The mosaic was prepared to support BiomasBR Program to produce The European Union LandMark Deforestation Map 2020. The false color composition is based on the MSI bands 11, 8 and 4 assigned to RGB channels. The temporal composition encompasses 01-month of images from december 2020, with a best pixel selection approach called Least Cloud Cover First (LCF). More information on LCF can be found at Brazil Data Cube web site (https://brazil-data-cube.github.io/specifications/processing-flow.html#temporal-compositing). This Image Mosaic used more than 15000 Sentinel-2 scenes and was generated based on an existing data cube of Sentinel-2 images.
