The function allows to graphically check that all the optional runtime dependencies are installed.

check_sen2r_deps()

Value

NULL (the function is called for its side effects)

Details

This package needs some external dependencies in order to run specific actions:

  • Sen2Cor for atmospheric correction;

  • GDAL for cloud mask smoothing and buffering;

  • aria2 to download SAFE images with an alternative downloader.

This function opens a GUI which allows to check that these dependencies are installed. This check is highly suggested before using the library for the fist time, in order to avoid errors.
