[GRASS-user] Point vector aggregation to raster

Hello,

I have a vector layer with several thousand points from which I need to create
a raster containing the sum of an attribute of the points covered by each
cell. How can I do this? In the documentation of v.to.rast there is no
indication of the way it converts from point to cell.
Many thanks in advance

“Que la tierra se vaya haciendo camino ante tus pasos,
que el viento sople siempre a tus espaldas,
que el sol brille cálido sobre tu cara,
que la lluvia caiga suavemente sobre tus campos y,
hasta tanto volvamos a encontrarnos,
que Dios te lleve en la palma de su mano.”

You should be able to do this using v.out.ascii and r.in.xyz.
