Classified land cover and land use maps generated automatically with artificial intelligence algorithms.
The Brazil Data Cube project proposes the usage of data cubes prepared from remote sensors on board of the satellites Aqua, Terra, Landsat 8, Sentinel-2 and CBERS 4. These data cubes improve the amount of information about the dynamics of Land Use and Land Cover in Brazil that can be extracted by means of Machine Learning and Time Series analysis
Using the data cubes made of images from Landsat 8 and Sentinel-2 (collections LC8_30_16D_STK & SEN2COR_10_16D_STK), we generated Land Use and Land Cover maps for 3 Brazilian biomes: Amazônia, Cerrado, and Pantanal (Figure 1). These classification were made using two R packages (Ihaka & Gentleman, 1996): sits (v0.12.0) for classifying (Simões et al., 2021a) and rstac (Simões et al., 2021a) to exchange data over the Internet.
The samples used for training the classification models were collected in different ways: (1) in situ, that is by making field inspections; (2) by visual interpretation of Remote Sensing imagery with help of BDC’s staff or other specialists; and (3) by matching already existing Land Use and Land Cover maps.
The classified maps along with their metadata are available at BDC’s Internet portal and they are available at:
