Yes. I have added a related example here:<br>
<br>
<a href="http://grass.osgeo.org/grass70/manuals/v.to.rast.html#convert-vector-points-to-raster-with-raster-cell-binning" rel="noreferrer" target="_blank">http://grass.osgeo.org/grass70/manuals/v.to.rast.html#convert-vector-points-to-raster-with-raster-cell-binning</a><br>
<br>
(while it does not really fit to that manual page it is expected<br>
there. Perhaps we need to really enhance v.to.rast to do such a job<br>
right away).<br>
