Displacer

Solves proximity conflicts between features using a variant of the Nickerson displacement algorithm. This transformer is usually used after generalization.

Input and Output Ports

The features routed into the transformer through the Base port are geometrically frozen (cannot move).

The features routed in through the Candidate port are compared against the Base feature(s), displaced as necessary, and exit through the Displaced port. If no displacement occurred, they exit through the Untouched port.

Each comparison/displacement is independent of the others.

Base features with geometries other than point, curve or area (polygon or ellipse or donut) will exit through the InvalidBase port. Candidate features with geometries other than point, curve or simple area (polygon or ellipse) will exit through the InvalidCandidate port.

The ExtraBase port holds extra Base features as described in the Base Type parameter below.

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.
