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

- -pregerr, --pregerr
- calculate perpendicular regression between two raster datasets and get root mean square error
- -v level, --verbose level
- verbose mode when positive
