Calculate Length Activity

Description

The Calculate Length activity calculates the length of the input geometry.

Usage

You may need to calculate the length or perimeter of a geometry. You could take the geometry from a parcel feature and calculate its perimeter to estimate the length of a fence.

Inputs

Geometry

Required

Type: esri.Geometry (3.x, 4.x)*

The input geometry whose length is to be calculated.

Geodesic

Optional

Type: Boolean

Determines whether the length to be calculated is geodesic. If not, the planar length is returned.

The default is false.

Note: geodesic only works with WGS84 (wkid: 4326) and Web Mercator spatial references.

Unit

Optional

Type: String | Number

The measurement unit of the return value.

Defaults to the units of the input geometry.

Known values: meters | feet | kilometers | miles | nautical-miles | yards.

* Geocortex Workflow uses different versions of Esri's ArcGIS API for JavaScript depending on the type of host application. See Underlying Technologies for information.

Outputs

length

Type: Number
