You are here: Geometric OperatorsTopologyBuilder


Computes topology on input point, line, and/or area features.

This transformer is typically used to determine topological relationships to aid in decision making in later transformers (for example, the FeatureColorSetter).

This transformer does not assume that all input data is clean and noded properly unless Assume Clean Data is set to Yes. It takes any data and constructs the resulting topology after computing any intersections that are present in the input data.

Input Ports

Output Ports

Each topological primitive is output with attributes describing its topological relationships.

Note: Unlike most transformers, you cannot name these attributes.





Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
