Brazil Data Cube is a project that is being developed by the Brazil’s National Institute for Space Research (INPE), since January 2019, that aims to create multidimensional data cubes of analysis-ready from medium-resolution Earth observation images….
The article is the result of his PhD on Applied Computing at INPE. It presents an open source R package, SITS, state-of-the-art in satellite image time series classification, which provides full support to the workflow for the generation of land use and land cover maps using machine learning techniques. The software works in different cloud computing environments, with a simple set of functions that makes it easy to use. In the article, it is shown that the time series classification approach using machine learning produces land use and land cover maps with good accuracy through a case study in the Brazilian Cerrado biome, for the year 2018, using the data cubes generated by the project.
The BDC team will present tomorrow (June, 16th) in the GEO-GFOI Workshop a live demonstration of the R package SITS (Satellite Image Time Series Analysis) running in the SEPAL platform.
SITS is an open source R package for satellite image time series analysis and machine learning. It supports the complete cycle of data analysis for land classification.
SEPAL (System for earth observations, data access, processing & analysis for land monitoring) is an open source platfom developed by the Open Foris team in Forestry Department of the United Nations Food and Agriculture Organization (FAO).
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 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:
