therefore to be able to classify accurately the relations between all contours
so as to describe features more precisely and extract more information
from the contour tree.
Second, work presented here only considers isobaths. On a longer term,
other items on nautical chart can be added. For example, soundings can be
included in the generalization process as micro-agents belonging to fea-
tures. Specific constraints would then be added for sounding selection and
to generalize both contours and soundings simultaneously.
