Parameters:

base=name [required]

Name of base raster map
cover=name [required]

Name of cover raster map
quantiles=integer

Number of quantiles
percentiles=float[,float,...]

List of percentiles
Default: 50
bins=integer

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.

SEE ALSO

r.quantile, r.stats.zonal, r.statistics
