pkstatprofile(1)

NAME
pkstatprofile - program to calculate statistics in temporal or spectral profile

SYNOPSIS
\FCpkstatprofile\F[]
\FC-i\F[] input \FC-o\F[] output [\FC-f\F[] function] [options]

DESCRIPTION
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
