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
Lower right y value bounding box
-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
generate random numbers
-mean, --mean
calculate mean
-median, --median
calculate median
-var, --var
calculate variance
-skew, --skewness
calculate skewness
-kurt, --kurtosis
calculate kurtosis
-stdev, --stdev
calculate standard deviation
-sum, --sum
calculate sum of column
-mm, --minmax
calculate minimum and maximum value
-min, --min
calculate minimum value
-max, --max
calculate maximum value
-src_min value, --src_min value
start reading source from this minimum value
-src_max value, --src_max value
stop reading source from this maximum value
-hist, --hist
calculate histogram
-hist2d, --hist2d
-nbin value, --nbin value
number of bins to calculate histogram
-rel, --relative
use percentiles for histogram to calculate histogram
-kde, --kde
Use Kernel density estimation when producing histogram. The standard deviation is
estimated based on Silverman's rule of thumb.
-cor, --correlation
calculate Pearson produc-moment correlation coefficient between two raster datasets
(defined by -c col1 -c col2)
-rmse, --rmse
calculate root mean square error between two raster datasets
-reg, --regression
calculate linear regression between two raster datasets and get correlation
coefficient
-regerr, --regerr
calculate linear regression between two raster datasets and get root mean square
error
-preg, --preg
calculate perpendicular regression between two raster datasets and get correlation
coefficient
-pregerr, --pregerr
calculate perpendicular regression between two raster datasets and get root mean
square error
-v level, --verbose level
verbose mode when positive
