Dear List, Does anyone have any tricks for masking out cloud and haze affected regions of ETM+ data? I've tried thresholding Band 1 and also ratioing Band 1 and Band 6. They both give satisfactory and substantially similar results on discrete clouds but (as expected) lose definition at the diffuse cloud edges. I plan to classify the images, so would like to completely mask out clouds and also isolate haze. Are there any better ways to do it?
