Extra.QA

maskClouds(x[, method, prob, maskCirrus, ...])

Masks clouds and shadows in an image or image collection (valid just for Surface Reflectance products).

preprocess(x, **kwargs)

Pre-process the image, or image collection: masks clouds and shadows, and scales and offsets the image, or image collection.
