The ATBD (Algorithm Theoretical Basis Document) describes the entire process of development and production of the maps and algorithms in the MapBiomas Chaco Collection 2.
The ATBD is a dynamic document that is constantly updated adding new information and learning.
There is a General ATBD for MapBiomas Chaco that details the method of Collection 2.
MAPBIOMAS CHACO METHODOLOGY - COLLECTION 2
Below you will find the main features, how the work is organized and an overview of the MapBiomas Chaco method for generating land cover and land use maps and transition/land use change maps between different years.
You can access the ATBD (Algorithm Theoretical Basis Document) with all the methodology description and algorithms by accessing the link below.
All annual land cover and land use maps of the MapBiomas Chaco are produced from the pixel-by-pixel classification of Landsat satellite images. The whole process is carried out on the Google Earth Engine platform which offers immense cloud processing capabilities. The IBGE 1 x 1.5o (lat/long) tiles are used to facilitate the parameterization of the algorithms and the organization of all the processing stages.
HOW WE ARE ORGANIZED
For mapping, programmers, remote sensing specialists, and conservation and land use specialists are organized into teams for each country as they have leading institutions as part of their network.
The diagram below illustrates the main stages in the process of generating the annual MapBiomas Chaco land cover and land use maps and transition maps.
