The CBERS-4A WFI – Paraíba is a mosaic generated and made available by the Brazil data Cube (BDC) project covering the entire Paraíba state, in northeastern Brazil.
The mosaic uses surface reflectance images from the CBERS-4A satellite, WFI imaging camera (or sensor) with 55 meters of spatial resolution. The technologies developed in the Brazil Data Cube project helped in the generation of the mosaic, mainly in the stages of scene selection and composition of tiles free of clouds and cloud shadows. The product generation uses the composition function (Stack) to select the best pixel belonging to the months of July, August and September 2020.
The step of joining the tiles and cutting was done manually, and finally, Geotiff was converted from 16 bits to 8 bits to save space. The final product is an RGB color composite of the respective NIR (B16), Red (B15) and Green (B14) bands.
The CBERS-4A WFI Mosaic – Paraíba can be accessed through the Brazil Data Cube portal and also through GIS applications through the OGC WMS service, using the following address:
