MinimumSpanningCircleReplacer

Replaces the geometry of the feature with a polygon representing its minimum spanning circle. The minimum spanning circle is defined as the smallest circle that encloses all vertices of the passed-in feature.

If the feature was an aggregate feature, a single minimum spanning circle is computed from all vertices of all geometries in the aggregate. If the feature was a linear feature, it will be turned into a polygonal feature. No change is made to a point feature.

Parameters

ClosedMode

In Replace Geometry mode, each feature's geometry will be replaced with the calculated circle. In Set Attributes mode, the input geometry will be left untouched and the properties (location and radius) of the circle saved as the designated attributes on the feature.

ClosedCenter X, Y Attributes

The name of the attribute into which the x and y values of the circle center will be placed.

ClosedRadius Attribute

The name of the attribute into which the radius of the circle will be placed.

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.
