Overview
An image mosaic of the CBERS-4 images covering the Paraíba State in Brazil. It was created from a CBERS-4 data cube, with 64 meters of spatial resolution images, 3 months of temporal step (from April until June), for the year of 2020, using the Least Cloud Cover First (LCF). RGB composition of the Red (B15), NIR (B16) and Blue (B13) bands.
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.
