Generalizer

Transforms or measures geometry features based on a specified algorithm.

There are four types of algorithms:

  • Generalizing algorithms: Reduce the density of coordinates by removing vertices.

  • Smoothing algorithms: Determine a new location for each vertex.

  • Measuring algorithms: Calculate the location of points, and return a list of these points (for example, to measure the sinuosity of a feature).

  • Fitting algorithms: Replace the original geometry completely, with a new feature fitted to a specified line (for example, to minimize the orthogonal distance to the original).

Usage Notes

  • Null geometries that are input will be output unchanged.

  • To maintain topologies that involve other features while generalizing, consider using the SherbendGeneralizer transformer.

Editing Transformer Parameters

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.

For more information, see Transformer Parameter Menu Options.
