Calculates the "angularity" of a linear or area feature. Angularity indicates the degree of curvature of a feature. The higher the value, the more curved its geometry.
A value of 0 indicates the geometry is a straight line. This mode works on linear and polygonal geometries, and all other geometries will receive a value of 0.
The calculation of this property utilizes the angle between segments and, as a result, linear and polygonal features must have more than one segment to receive a non-zero value. Arcs are stroked into lines before determining this value. The actual value is the sum of the angles between the segments divided by the total length of the segments.
Input Ports
Input
This transformer accepts all features. Only linear and polygonal features with more than one segment will receive a non-zero value.
Output Ports
Output
All processed features are output through this port.
Parameters
Angularity Attribute
The name of the attribute that will contain the angularity calculation.
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.
