Calculates the area of a polygonal object and stores the value in an attribute. The area is calculated in square map units, whatever they are.
The type of area calculation that is performed is chosen by the Type parameter.
This transformer accepts any feature. Features without an area geometry will have an area of 0.
Features with the calculated area are output through this port.
For the traditional projected area of features, use "Plane Area" as the type.
For 2D/2.5D geometries, the option of calculating 3D sloped areas is available by selecting "Sloped Area" as the type. This option calculates the surface area of the feature, taking height (Z) coordinates into consideration.
The attribute that contains the area of the polygonal feature.
The multiplier parameter can be used to scale the area from being square ground units (the units of the feature's coordinates) to something else. This parameter may either be entered as a number, or can be taken from the value of a feature attribute by selecting the attribute name from the pull-down list.
For 3D geometries, the surface area is always returned.
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.
