Calculate Geometry Fields Attribute Rule (Data Management Tools)

Summary

Generates an attribute rule that calculates a feature's geometry information and writes it to a given field. Geometry attributes represent the spatial or geometric characteristics and location of each feature, such as length or area and x-, y-, z-coordinates, and m-values.

Usage

• Length and area calculations will be in the units of the input features' coordinate system unless different units are specified in the Length Unit and Area Unit parameters.

• The optional coordinate format parameter requires spatial reference of the input tables to be a geographic coordinate system.

• Tool will fail to run if the input class is being edited.

• Rules created with this tool are configured to trigger only on edits to the SHAPE field and fields set as a target for geometry calculations.

Parameters

• Dialog
• Python

Label	Explanation	Data type
Input Table	The table or feature class that will have the new rule applied.	Feature Layer; Annotation Layer; Dimension Layer; Oriented Imagery Layer; Catalog Layer
Output Folder	The folder where the output will be saved.	Folder
Geometry Attributes	The fields in which the specified geometry properties will be calculated. You can select an existing field or provide a new field name. If a new field name is provided, the field type is determined by the type of values that are written to the field. Count attributes are written to long integer fields; area, length, and x-, y-, z-coordinate, and m-value attributes are written to double fields; and coordinate notations such as Degrees Minutes Seconds or MGRS are written to text fields. Unless otherwise noted, area and length properties are planar measurements using 2D Cartesian mathematics.
