We've been scratching our heads over how to tackle this for some
time, and are no more illuminated than when we started. I hope
you can help. Our task is thus: how to draw a lake with a solid
outer perimeter line and no lines between internal wetlands,
shoals and shallows? 'Tis a relatively straightforward process
with Arcinfo coverages and Regions, but alas, that is no longer
a viable option for us, the datasets we use now are too large
and the lack coverage editing ability in Arcmap crucial. Can
cartographic representation solve our dilemma? Is it possible to
create something like the below without resorting to creating
(and managing) duplicating, or triplicating, geometries whose
sole purpose is better looking maps? With a feature class:
Boundary between river and lake is visible. Keeping them as
distinct polygons in one feature class allows a name attribute
(the river and laker differ). Elsewhere the heavy line implies a
sharp boundary between lake and shallows/intermittent lake,
however the actual edge i
