pkstatogr - program to calculate basic statistics from vector file
Contents
Description
pkstatogr calculates basic statistics on attributes of a vector file. Examples of the basic statistics
include: minimum, maximum, median, mean and standard deviation. Histograms (in percentage or absolute
values) can also be calculated. The attribute of interest can be selected using the option -n|--fname.
Values defined by the -nodata option, or not within the limits set by the options -src_min and -src_max
are ignored for the statistics.
Example
report histogram of values in FIELDID (to standard output)
pkstatogr-iinput.shp-fFIELDID-n100
report min, max, mean and standard deviation of values in FIELDID (to standard output)
pkstatogr-iinput.shp-fFIELDID-min-max-mean-stdev

Name
pkstatogr - program to calculate basic statistics from vector file
Options
-ifilename, --inputfilename
Input image file(s). If input contains multiple images, a multi-band output is created
-lnlayer, --lnamelayer
Layer name(s) in sample (leave empty to select all)
-nattribute, --fnameattribute
Fields on which to calculate statistics
-nodatavalue, --nodatavalue
Set nodata value(s)
-src_minvalue, --src_minvalue
Set minimum value for histogram
-src_maxvalue, --src_maxvalue
Set maximum value for histogram
-s, --size
Sample size (number of points)
-mm, --minmax
Calculate minimum and maximum value
-min, --min
Calculate minimum value
-max, --max
Calculate maximum value
-mean, --mean
Calculate mean
-median, --median
Calculate median
-stdev, --stdev
Calculate standard deviation
-hist, --hist
Calculate histogram
-nbinvalue, --nbinvalue
Number of bins to calculate histogram
-rel, --relative
Use percentiles for histogram to calculate histogram
-kde, --kde
Use Kernel ⟨http://pktools.nongnu.org/html/classKernel.html⟩ density estimation when producing
histogram. The standard deviation is estimated based on Silverman's rule of thumb
-vlevel, --verboselevel
Verbose level
