SYNOPSIS

r.stats.quantile

r.stats.quantile --help

r.stats.quantile [-rp] base=name cover=name [quantiles=integer] [percentiles=float[,float,...]] [bins=integer] [output=name[,name,...]] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

-r: Create reclass map with statistics as category labels

cover=name [required]: Name of cover raster map
quantiles=integer: Number of quantiles
percentiles=float[,float,...]: List of percentiles; Default: 50
bins=integer: Number of bins to use; Default: 1000
output=name[,name,...]: Resultant raster map(s)

DESCRIPTION

r.stats.quantile is a tool to analyse exploratory statistics of a floating-point "cover layer" according to how it intersects with objects in a "base layer". It provides quantile calculations as selected "zonal statistics".

NOTES

r.stats.quantile is intended to be a partial replacement for r.statistics, with support for floating-point cover maps. It provides quantile calculations, which are absent from r.stats.zonal.
