nothing was extracted or everything was extracted?

if everything was extracted (ie internal isles have centroids + category
numbers) then 'v.extract -d' should work.
if nothing was extracted then you might have to run 'v.category option=add'.
use 'd.vect cats=1-9999999' and see what plots? isles should not be
filled or have centroid marks. ?
