KNOW THE STEPS OF THE MAPBIOMAS AMAZONIA METHODOLOGY
Here you will find the main features, how we organize our work, and an overview of the methodology MapBiomas Amazonia uses to generate the land cover/use maps and transition / land-use change maps.
You can access the ATBD (Algorithm Theoretical Basis Document) that describes in detail the methodology and algorithms used.
All MapBiomas Amazonia annual land cover/use maps were produced from a pixel by pixel classification of the Landsat satellite images. The whole process is carried out using machine learning algorithms at the Google Earth Engine platform, which offers immense cloud processing capabilities. In order to facilitate the parameterization of the algorithms and the organization of all the processing stages, a total of 648 charts are used. Each chart has a 1 x 1.5 degree (lat / long) dimension.
HOW ARE WE ORGANIZED?
Teams of programmers, specialists in remote sensors, conservation, and land use are organized by country, where at least one institution per territory leads the process nationally. In this collection, new teams were formed to lead the methodological process of each cross-cutting theme.
OVERVIEW OF THE METHODOLOGY
The following diagram illustrates the key steps in the process of generating the annual land cover/use maps of MapBiomas Amazonia as well as the transition and land-use change maps.
