NOTE This procedure is for drawing objects only. There is no equivalent for
geospatial feature data. However, you can use buffers to analyze features by
proximity and perform overlay analysis on two geospatial feature layers. See
Buffering Features in Your Map (page 1308)and Overlaying Two Feature Sources
(page 1316).
To fix crossing objects
1 Use drawing cleanup (page 765) to break the crossing objects.
2 Optionally, detect duplicate centroids, incomplete areas, and
sliver
polygons
(page 841).
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.

Creating Topologies for a Land Use Map
You can create a specialized polygon topology for a land use or land cover
map.

geospatial feature data. However, you can use buffers to analyze features by
proximity and perform overlay analysis on two geospatial feature layers. See
