Dear users,
I have a map where I have to remove all the isles present inside other
big poligons...
in some previous e-mails someone said to use v.extract
list=1-9999999 .... but I wasn't able to obtain results this way...
do you know if there are other ways to do this???
thank you!!!

nothing was extracted or everything was extracted?
do you know if there are other ways to do this???
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. ?
