How do you add a topology rule in Arcgis?

Here is the process used to create a topology using ArcCatalog.

1. Right-click the feature dataset to which you want to add a topology, point to New, then click Topology.
2. Click Next.
3. Name the new topology and specify the cluster tolerance.
4. Click Next.
5. Next, choose the feature classes that will participate in the topology.

Why topology is important in GIS?

Topology has long been a key GIS requirement for data management and integrity. Topology is also used for analyzing spatial relationships in many situations, such as dissolving the boundaries between adjacent polygons with the same attribute values or traversing a network of the elements in a topology graph.

What are the point rules in geodatabase topology?

Point rules. Requires that points in one feature class must be covered by the endpoints of lines in another feature class. This rule is similar to the line rule Endpoint Must Be Covered By except that, in cases where the rule is violated, it is the point feature that is marked as an error rather than the line.

What are the rules for validating a topology?

Any line feature, such as these lines in red, that would collapse when validating the topology is an error. Requires that lines not overlap with lines in the same feature class (or subtype). This rule is used where line segments should not be duplicated, for example, in a stream feature class. Lines can cross or intersect but cannot share segments.

When do you need a topology rule in ArcGIS?

This rule is useful when modeling areas that are subsets of a larger surrounding area, such as management units within forests or blocks within block groups. Requires that boundaries of polygon features must be covered by lines in another feature class.

Can a point be covered by a line in a feature class?

Requires that points in one feature class must be covered by the endpoints of lines in another feature class. This rule is similar to the line rule, “Endpoint Must Be Covered By”, except that, in cases where the rule is violated, it is the point feature that is marked as an error, rather than the line.
