pkstatprofile

pkstatprofile
-i input -o output [-f function] [options]

pkstatprofile calculates statistics for a temporal (time series) or spectral profile.

Function	Description
mean	calculate mean in window
median	perform a median filter in spatial (dx, dy) or spectral/temporal (dz) domain
var	calculate variance in window
stdev	calculate standard deviation in window
min	calculate minimum in window
max	calculate maximum in window
sum	calculate sum in window
mode	calculate mode of all values
ismin	1 if value is minimum, else 0
ismax	1 if value is maximum, else 0
per	calculate percentile in time series (provide percentage value as argument)
prop	calculate proportion
nvalid	report number of valid observations

Calculate min and max NDVI in time series
