From the Landsat mosaics, the classifications that result in land cover and land use maps are carried out for each year. Within the logic proposed by MapBiomas the maps will be updated every time an improvement in the classification algorithms is achieved. The classification methodology is dynamic and procedural, with the purpose of improving the classification of each typology.
Here you can access the land cover and land use maps.
Important: when composing a single mosaic or calculating statistics on maps it should be noted that:
- For area calculation it is necessary to use an appropriate metric projection.
- All data is in GeoTiff format and has LZW compression. To get the reference of the codes with the caption classes click here.
The most current MapBiomas Collection can always be accessed in three ways:
1. browsing online through the dodashbard: https://plataforma.pampa.mapbiomas.org
2. access the data asset in Google Earth Engine:
3. download by country, province, department and any other desired geometry using Toolkits prepared in Google Earth Engine (GEE). Access the tutorial video to learn how to use the toolkit. Instructions are also available on Github. The following data are currently available:
Transition Maps Legend
The transition maps have codes calculated by joining the first and second year codes, according to the formula below:
(year1 x 100) + year2
303 = forest that remained forest
314 = forest that has been converted to farming
1414 = farming that remained farming
1422 = farming that has been converted to non vegetated area
Mosaic Quality Caption
Obs. All data are downloaded with a .CSV table (comma separated text) with the calculated areas. This script is an example of how to perform the Area Calculation in the GEE.
