MinimumSpanningCircleReplacer

Calculates a circle containing all vertices of the input feature, output as either attribute values or geometry.

Jump to Configuration

Typical Uses

  • Calculating circular boundaries around features

How does it work?

The MinimumSpanningCircleReplacer receives features with any type of geometry and calculates a 2D circular ellipse that encloses all of the feature’s vertices.

The transformer has two modes:

  • Replace Geometry - replace the input feature geometry with the circle

  • Set Attributes - add the center coordinates and radius as attribute values, keeping the input geometry intact.

One circle is generated for each feature or aggregate.

Features with 3D geometry such as 3D objects and point clouds will have a circle generated that encloses their footprint in 2D.

Point features are passed through unchanged (unless they are aggregated or multi-point).

Examples

Usage Notes

  • To generate a circle around multiple features, use an Aggregator before the MinimumSpanningCircleReplacer.

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.
