I just downloaded my first group of landsat 8 surface reflectance data files. In this package contains sr bands 1-7 (I hope to use some of these to create an NDVI) as well as numerous files called: sr_cloud, cf_mask, and cf_mask_conf (all tif files). I am using arcgis.
I am assuming that these files are utilised to help remove cloud coverage from the images. However, I have never dealt with any of these types of files (srcloud, cfmask, etc.) and I have no idea regarding how they work or how to use them to effectively remove clouds. Does anyone have any experience working with these kinds of files and know how I may effectively use to remove clouds?
