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

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
