CBERS4 images mosaic of Brazil by the Brazil Data Cube Project

A CBERS4 image mosaic of Brazil was launched today by the Brazil Data Cube project team.

This mosaic uses CBERS4/WFI images, surface reflectance, with 64 meters of spatial resolution.

It was generated with technologies under development in the Brazil Data Cube project, using the best pixel (free from cloud and cloud shadows) chosen in a three-month period (April, May and June 2020).

The product uses a RGB composit with red(B15) , NIR(B16) and blue(B13) bands.

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

It is also possible to access this mosaic in GIS applications through the OGC WMS service, using the following address:

Two new publications from BDC project team

The proceedings of 2020 Latin American GRSS & ISPRS Remote Sensing Conference is available at IEEE Explore with two papers written by the Brazil Data Cube project team.

The first paper describes the INPE’s initiatives in using remote sensing images and cloud services of the Amazon Web Services (AWS) infrastructure to improve land use and cover monitoring.

The second paper propose a new unsupervised segmentation algorithm based on the Conditional Random Fields (CRF) theory.

Virtual workshop Digital Earth Americas

Brazil, Mexico, Colombia and Chile presented today (August, 19) their initiatives and experiences in creating Earth observation data cubes in a virtual workshop about Digital Earth Americas organized by CEPAL, NASA and INEGI. The workshop attendees discussed visions for a solution that provides relevant Earth observation data for the benefit of the Americas. The Brazil Data Cube project was presented in this workshop by INPE researchers.
