Dear Matteo,
I just found out something interesting. As I mentioned in my previous email, I
tried the code you proposed and could see the diffference from the old code,
basically a smoother plot. However, the plot didn't change corresponding to
differenct quality thresohold (1, 2, 3, 4 and 5).
Dear Matteo,
Many thanks for the help!
I just tried it on a small raster stack and it worked. The resulting time
series looks better. I will keep trying with other threshold values(2,3,etc.)to
compare the resulting graphs for improved visual interpretation.
Best,Amit

Dear Amit,
Thats correct, if you want to use only pixel of quality you have to set 0
as threshold (everything > than threshold is set to 0 weight). But for what I
remember, and this might explains your result with all 0s, is that does
not exist in MODIS data despite the fact that it is
Hello!
I use MODIS package to smooth MODIS NDVI raster time series.
Just wanted to try how would it look like if I used the best qulity pixels
only.makeWeights function took about two days and resulted in raster stack of
zeros. According to MODIS, the best qulity is 0, hence I used 0 as the
thr
