When to ignore an error in geodatabase topology?
You can either ignore this error or mark it as an exception. Use this rule on data that must completely cover an area. For example, soil polygons cannot include gaps or form voids—they must cover an entire area. Create Feature: The Create Feature fix creates new polygon features using a closed ring of the line error shapes that form a gap.
Which is larger cluster tolerance error or polygon error?
This fix can be applied to one or more Must Be Larger Than Cluster Tolerance errors. Any polygon feature, such as the one in red, that would collapse when validating the topology is an error.
What can you do with topology checker plugin?
The Topology Checker Plugin Topology describes the relationships between points, lines and polygons that represent the features of a geographic region. With the Topology Checker plugin, you can look over your vector files and check the topology with several topology rules.
Are there any predefined fixes for Topology rules?
Some topology rules, however, have no predefined fixes. Once you have discovered the topology errors, you can select the error on the map with the Fix Topology Error tool , or select the error from within the Error Inspector. For a poster of the available topology rules and examples of them, see the ArcGIS Geodatabase Topology Rules PDF.
Why are feature classes excluded from a topology?
There are several reasons for a feature class to be excluded from participating in a topology: Determine the reasons each feature class is unable to participate in the topology and reevaluate whether that feature class should participate in the topology.
Why is my topology not created in ArcCatalog?
Attempting to create a new topology from within ArcCatalog produces the following error message: “Cannot create topology. The selected feature dataset does not contain any feature classes which can participate in a topology.”
