SYNOPSIS

r.vect.stats

r.vect.stats --help

r.vect.stats input=name output=name [column=name] [method=string] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

--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:

input=name [required]: Name of input vector map; Or data source for direct OGR access
output=name [required]: Name for output raster map
column=name: Name of attribute column for statistics
method=string: Statistic to use for raster values; Options: n, min, max, range, sum, mean, stddev, variance, coeff_var, median, percentile, skewness, trimmean; Default: mean; n: Number of points in cell; min: Minimum value of point values in cell; max: Maximum value of point values in cell; range: Range of point values in cell; sum: Sum of point values in cell; mean: Mean (average) value of point values in cell; stddev: Standard deviation of point values in cell; variance: Variance of point values in cell; coeff_var: Coefficient of variance of point values in cell; median: Median value of point values in cell; percentile: Pth (nth) percentile of point values in cell; skewness: Skewness of point values in cell; trimmean: Trimmed mean of point values in cell

DESCRIPTION

r.vect.stats bins points from a vector map into a raster map.

Use g.region to set the extent and resolution of the resulting raster.

EXAMPLES

Calculate number of schools in grid of spatial resolution 1km:

g.region res=1000 vector=schools_wake
r.vect.stats input=schools_wake output=schools_count

Calculate sum of atribute column CAPACITYTO:

r.vect.stats input=schools_wake output=schools_capacity_sum column=CAPACITYTO method=sum

Number of schools in grid of spatial resolution 1km

Sum of atribute column CAPACITYTO in grid of spatial resolution 1km

Figure: Number of schools (left part) and sum of CAPACITYTO attribute column (right part) in grid of spatial resolution 1km.
