NAME¶
pkstatprofile - program to calculate statistics in temporal or spectral profile
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
pkstatprofile -i modis_ndvi_2010.tif -o modis_stats_2010.tif -f min -f max
