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