sen2r is an R library which helps to download and preprocess Sentinel-2 optical images. The purpose of the functions contained in the library is to provide the instruments required to easily perform all the steps necessary to build a complete Sentinel-2 processing chain, without the need of any manual intervention nor the needing to manually integrate any external tool.

In particular, sen2r allows to :

• Retrieve the list of available products on a selected area.
• Download them.
• Obtain the required products (Top of Atmosphere radiances, Bottom of Atmosphere reflectances, Surface Classification Maps, True Colour Images)
• Mask cloudy pixels.
• Computing spectral indices and RGB images.
