NAME

       pkstat - calculate basic statistics from raster dataset

SYNOPSIS

       pkstat [options]

DESCRIPTION

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

OPTIONS

       -i filename, --input filename
              name of the input raster dataset

       -b band, --band band
              band(s) on which to calculate statistics

       -f, --filename
              Shows image filename

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

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

       -ulx value, --ulx value
              Upper left x value bounding box

       -uly value, --uly value
              Upper left y value bounding box

       -lrx value, --lrx value
              Lower right x value bounding box

       -lry value, --lry value

       -nodata value, --nodata value
              Set nodata value(s)

       -down value, --down value
              Down sampling factor (for raster sample datasets only).  Can be used to create grid
              points.

       -rnd number, --rnd number
