Hi Stevecim,
In your original post you were speaking of needing to boolean the continents away from the globe.. If all you want is lines, then you could probably do an "isect" command and generate outlines of the continents.

Look under construct-curve-isect and give that a whirl. Then you could also trim the globe surface with those curves and have continent surfaces too... Maybe run "ExplodeMove" on the seperated lot, to make a cool 3d image of the thing.
