First check If the polylines are imported as closed boundaries with:
v.info -t
(Note the line “boundaries=…”)
If you don’t have closed boundaries, you’ll have to do some cleaning to snap the nodes of the polylines together with v.clean … tool=snap, etc.
Then just run:
v.centroids out=
to add centroids to each closed boundary.
