Hello Sir,
I have used fmask for Landsat 8 OLI data and my study area is in Punjab, India.
I have observed two different things in fmask results as my study include two
season data, Pre Monsoon (May month) and Monsoon (August month). Both season
data were covered with cloud and shadow and for May month (Pre monsoon season)
data only 60 % accuracy reported, even cloud free pixels also mapped as cloud
which include waterbodies, crop land and vegetation. But for august month
(monsoon season) the accuracy were around 90%, means it worked correctly for
this season. I don't know why it happened, is there any seasonal affect on
cloud condition. How can I achieve more accuracy for May month data. I have
used same command (default as suggested in tutor) for both season data to run
fmask.
My other question is related to DN and TOA. Why it requires to convert DN to
TOA for further data processing, what difference it make as compare to DN in
results ?
