The land cover and land use classifications of MapBiomas Amazonía Collection 3 are based on LANDSAT mosaics. For each 1:250,000 chart, in each year evaluated (1985-2020), a specific mosaic was produced. 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 were defined according to a strategy to improve the classification results.

Annual mosaics contain 141 bands which include: LANDSAT spectral bands, indices, and fractional metrics from the Mixture Spectral Model. Also, some topographic and elevation features were used. For more information, see item 3.1 of the ATBD General.
