To Cleanup Data for a Polygon Topology

Clean up your data before creating polygon topology; eliminate gaps, intersections, or overlaps between any of the linework in a polygon topology. In addition, eliminate zero length objects or areas with missing centroids.

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.
