Cleaning Data for a Polygon Topology
Concept Procedure Quick Reference

To fix crossing objects

  1. Use drawing cleanup to break the crossing objects.
  2. Optionally, detect duplicate centroids, incomplete areas, and sliver polygons.
  3. Create the topology again.

    You can ensure there are no missing centroids by selecting the Create Missing Centroids option on the Create Polygon Topology - Create New Centroids screen.
