Can anyone help me to isolate any of the indicators one by one? Se2WaQ

[albertofrance]

Hi, herewith down this post is the complete script for analysing all 6 indicators Se2WaQ (Sentinel-2 Water Quality Script), Could anybody help me to isolate the script for anyone of them? Im afraid my knowledge in scripting is still very basic,

I really appreciate it! Alberto geovisualization.net
