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
