Table Of Contents
A polygon in a topology consists of a centroid containing information about the
surrounding links. Intersecting links can have nodes. A polygon can contain one or
more islands.
You cannot create a polygon topology from ellipses or from closed polylines
that share an edge or intersection with other polygons. You must explode a
closed polyline before you create the topology. You can use information from
different layers to define a polygon topology.
