I am sure you considered v.to.rast? # North Carolina sample dataset g.region raster=elevation res=5000 -pa # create vector hexagons v.mkgrid map=hexagons -h v.info -c hexagons # convert to raster model, requires the resolution to be increased (example: 5000m -> 250m) g.region res=250 -p v.to.rast input=hexagons output=hexagons use=cat # viz d.rast hexagons d.vect hexagons type=boundary Now you may turn them into cost surfaces.
