NAME
r.statistics2 - Calculates category or object oriented statistics (accumulator-based statistics).
KEYWORDS
raster, statistics
SYNOPSIS
r.statistics2
r.statistics2 help
r.statistics2 [-cr] base=name cover=name method=string output=name [--overwrite] [--verbose] [--quiet]
Flags:
- -c
- Cover values extracted from the category labels of the cover map
- -r
- Create reclass map with statistics as category labels
- --overwrite
- Allow output files to overwrite existing files
- --verbose
- Verbose module output
- --quiet
- Quiet module output
Parameters:
- base=name
- Name of base raster map
- cover=name
- Name of cover raster map
- method=string
- 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
- variance2: (2-pass) Variance of values in specified objects
- stddev2: (2-pass) Standard deviation of values in specified objects
- skewness2: (2-pass) Skewnes of values in specified objects
- kurtosis2: (2-pass) Kurtosis of values in specified objects
- output=name
- Resultant raster map
DESCRIPTION
r.statistics2 is intended to be a partial replacement for
r.statistics, with support for floating-point cover maps at the
expense of not support quantiles.
