SYNOPSIS
pkstatprofile -i input -o output [-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
