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.
