Know the steps of the Mapbiomas methodology

Below you will find the main features, the organization of the work and the overview of the MapBiomas methodology to generate the maps of land cover and land use as well as the transition maps/land-use change between different pairs of years.

You can access the ATBD (Base Document of Algorithm Theory) with all descriptions of methodology and algorithms by going to the link below.

General characteristics

All the annual land cover/use maps of the MapBiomas are produced from the pixel-per-pixel classification of Landsat satellite images. Every process is done with extensive machine learning algorithms through the Google Earth Engine platform that offers immense processing power in the cloud.
