In this example you will see how to add the Lots and LotIds feature classes to the topology so you can add rules to help you continue to clean up the data.

Before you can add topology rules for feature classes, you need to add the feature classes to the topology.

It is important to note that you are using this topology for the purpose of improving the polygon feature class you created from line work and points. You do not need to have the line or point feature classes to model the Lots—some organizations might decide to keep the LotLine feature class to provide easy annotation of lot boundary lengths, while others might not. Likewise, the Lots Parcel_ID attribute is now stored in the polygon feature class—you’re using the LotIds feature class to quality check the data you’ve created. You might well decide not to keep the LotIds feature class when you’ve finished checking the data.

In this example you add the Must Be Properly Inside topology rule to connect LotIds to Lots. This rule will be useful for finding places where lot polygons were not formed due to breaks in the line work.

In this example you also add the Must be Covered By Boundary Of rule to connect LotLines to Lots. This rule will be useful for finding polygons that were not completely split due to gaps in the line work.

After you add new feature classes or rules to a topology you need to validate the topology again.
