The land cover and land use classifications of MapBiomas Amazonía Collection 2 are based on LANDSAT mosaics. A mosaic has been produced for each 1:250,000 chart, for each year evaluated (1985-2018). Each mosaic is produced by the spatial integration of different LANDSAT images present in each chart and by a pixel-by-pixel temporal integration. The time intervals are defined according to a strategy to improve the classification results .

Annual mosaics contain up to 81 components per pixel, which includes 8 spectral bands plus various fraction metrics and spectral indexes.
