sits, an open-source R package for satellite image time series analysis using machine learning

Gilberto Câmara is part of the INPE, the National Institute for Space Research. In his talk, Gilberto described an open-source R package for satellite image time series analysis using machine learning. It supports the complete cycle of data analysis for land classification, while its API provides a simple but powerful set of functions. The software works in different cloud computing environments, including AWS, MS-Azure, and Digital Earth Africa. In sits, satellite image time series are input to machine learning classifiers, and the results are post-processed using spatial smoothing. Since machine learning methods need accurate training data, sits includes methods for quality assessment of training samples. The software also provides methods for validation and accuracy measurement. The package thus comprises a production environment for big EO data analysis. The package is available on github.com and the documentation is available on e-sensing.github.io.
