statistics,
zonal statistics
SYNOPSIS
r.stats.zonal

- --overwrite
- Allow output files to overwrite existing files
- --help
- Print usage summary
- --verbose
- Verbose module output
- --quiet
- Quiet module output
- --ui
- Force launching GUI dialog
Parameters:
- base=name [required]
- Name of base raster map
- cover=name [required]
- Name of cover raster map
- method=string [required]
- Method of object-based statistic
- Options: count, sum, min, max, range, average, avedev, variance, stddev, skewness, kurtosis, variance2, stddev2, skewness2, kurtosis2
- count: Count of values in specified objects
- sum: Sum of values in specified objects
- min: Minimum of values in specified objects
- max: Maximum of values in specified objects
- range: Range of values (max - min) in specified objects
- average: Average of values in specified objects
- avedev: Average deviation of values in specified objects
- variance: Variance of values in specified objects
- stddev: Standard deviation of values in specified objects
- skewness: Skewness of values in specified objects
- kurtosis: Kurtosis of values in specified objects

- kurtosis2: (2-pass) Kurtosis of values in specified objects
- output=name [required]
- Resultant raster map
r.stats.zonal is intended to be a partial replacement for
r.statistics, with support
for floating-point cover maps at the expense of not support quantiles.
