Two image mosaics of Brazil was launched today by the Brazil Data Cube project team. These mosaic were generated from Landsat-8/OLI images, surface reflectance, with 30 meters of spatial resolution.
These mosaics were generated by selecting best pixels (free of clouds and cloud shadows) in two periods of 6 months: (1) July 2017 to December 2017 and (2) January 2018 to June 2018. The products use RGB color composition of the SWIR1 (B6), NIR (B5) e RED (B4) bands.
The visualization and download of these mosaics can be done in the BDC portal: https://brazildatacube.dpi.inpe.br/portal/explore?collection=LC8-MOSAIC-BRAZIL_30_6M_MEDSTK-1
The Earth observation data cubes that were used to produce these mosaics, named Landsat-8 6M Cube (OLI) with all spectral bands from 1 to 7, are also available in the project portal.
In addition to the mosaics and the data cubes with 30 meters of spatial resolution, we offer other versions of mosaics with 64 and 250 meters, respectively. These mosaics can be download in GeoTIFF format from the following links:
