Overview
An image mosaic of the Landsat-8 images covering Brazil. It was created from a Landsat-8 data cube, with 30 meters of spatial resolution images, 6 months of temporal step (from January to June and from July to December), for the year of 2022, using the Mediam/Stack (MEDSTK) composition function. RGB composition of the SWIR1 (B6), NIR (B5) and Red (B4) bands.
The technologies developed in the Brazil Data Cube project helped in the mosaic generation, especially in the stages of scene selection and composition of the tiles free of clouds and cloud shadows.
The product generation uses the Mediam/Stack (MEDSTK) composition function for two periods: the first starts on July 1st and ends December 2017, the second starts on January 2nd and ends June 2018.
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 SWIR1 (B6), NIR (B5) and Red (B4) bands.
