# pkstat(1)

calculate basic statistics from raster dataset

## NAME

pkstat - calculate basic statistics from raster dataset

## SYNOPSIS

FC**pkstat**F\[0\]  \[*options*\]

## DESCRIPTION

**pkstat** is utility to calculate basic statistics from a raster dataset.

## OPTIONS

  name of the input raster dataset

- FC**-b**F\[0\] *band*, FC**--band**F\[0\] *band*

  band(s) on which to calculate statistics

- FC**-f**F\[0\], FC**--filename**F\[0\]

  Shows image filename

- FC**-stats**F\[0\], FC**--statistics**F\[0\]

  Shows basic statistics (calculate in memory) (min,max, mean and stdDev of the raster datasets)

- FC**-fstats**F\[0\], FC**--fstatistics**F\[0\]

  Shows basic statistics using GDAL computeStatistics (min,max, mean and stdDev of the raster datasets)

- FC**-ulx**F\[0\] *value*, FC**--ulx**F\[0\] *value*

  Upper left x value bounding box

- FC**-uly**F\[0\] *value*, FC**--uly**F\[0\] *value*
