NAME
r.quantile - Compute quantiles using two passes.
KEYWORDS
raster, algebra, statistics
SYNOPSIS
r.quantile
r.quantile --help
r.quantile [-r] input=name [quantiles=integer] [percentiles=float[,float,...]]
[bins=integer] [--help] [--verbose] [--quiet] [--ui]
Flags:
-r
Generate recode rules based on quantile-defined intervals
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--ui
Force launching GUI dialog
Parameters:
input=name [required]
Name of input raster map
quantiles=integer
Number of quantiles
Default: 4
percentiles=float[,float,...]
List of percentiles
bins=integer
Number of bins to use
Default: 1000000
DESCRIPTION
r.quantile computes quantiles in a manner suitable for use with large amounts of data. It
is using two passes.
EXAMPLE
Calculation of elevation quantiles (printed to standard-out):
g.region raster=elevation -p
r.quantile input=elevation percentiles=0.1,1,10,25,50,75,90,99,99.9
The output of r.quantile can be used for quantile classification:
g.region raster=elevation -p
r.quantile elevation quantiles=5 -r --quiet | r.recode elevation \
out=elev_quant5 rules=-
