r.vect.stats

Bins vector points into a raster map.

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

Example:

r.vect.stats input=name output=name

grass.script.run_command("r.vect.stats", input, output, column=None, method="mean", overwrite=False, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("r.vect.stats", input="name", output="name")

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

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