NuGet/Assembly: Carmenta.Engine.5.16.2.nupkg (in the CEOperators assembly)
Syntax
public class SizeOperator : UnaryOperator
Remarks
This operator calculates the area and perimeter length of polygon features, and the length of line features. Other feature types are passed through without intervention.
The result will be stored as the new attributes area and perimeter for polygons, and length for lines. The length and perimeter attributes will be expressed in meters, but the area will be expressed in square kilometers.
