The Sentinel-2 mosaic that covers the Brazilian Cerrado was generated and made available by the Brasil Data Cube (BDC) project to meet an institutional demand of the Terra Class Cerrado project, which has a partnership with INPE and Embrapa. The mosaic uses surface reflectance images extracted from the 16-day Sentinel-2 Data Cube at 10 meters spatial resolution.
The technologies developed in the Brazil Data Cube project assisted in the generation of the mosaic, mainly in the steps of scene selection and composition of tiles free of clouds and cloud shadows. Product generation uses the LCF (Least Cloud First) composition function to select the best pixel within the period starting in June and ending in September 2022. The steps of joining the tiles and cutting were done manually and Finally, Geotiff was converted from 16 to 8 bits to save space. The final product is an RGB colored composite of the respective NIR(B8), Red(B4) and Green(B3) bands.
Mosaico Sentinel 2 – Cerrado can be accessed through the Brazil Data Cube portal and also through GIS applications through the OGC WMS service, using the following address:
