Overview

The CBERS-4 AWFI Brazil is the first mosaic generated and made available by the Brazil Data Cube (BDC) project covering the entire national territory.
The mosaic uses surface reflectance images from the CBERS satellite, a WFI imaging camera (or sensor) with 64 meters of spatial resolution.
The technologies developed in the Brazil Data Cube project helped in the mosaic generation, 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) for the selection of the best pixel within the period that starts in April and ends in June 2020. The step of joining tiles and cutting were done manually, and finally, Geotiff has been converted from 16-bit to 8-bit to save space.
The final product is an RGB color composite of the respective red(B15), NIR (B16), and blue (B13) bands.

Data Access

The CBERS-4 AWFI Brazil Mosaic can be accessed through the Brazil Data Cube portal and also through GIS applications through the OGC WMS service, using the following address:

(Choose the cbers_full_resolution_tiles layer)

In addition to the mosaic with a resolution of 64 meters, we also offer two other versions, with 128 and 250 meters, respectively. These tiles can be downloaded in GeoTIFF format from the following links:
