pkstatprofile - program to calculate statistics in temporal or
spectral profile
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
