# 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 |

The input geometry whose length is to be calculated. |

Geodesic |

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 |

The measurement unit of the return value. Defaults to the units of the input geometry. Known values: meters | feet | kilometers | miles | nautical-miles | yards. |

* VertiGIS Studio 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 |

The calculated length. |

## Properties

For information about the ID, Display Name, and Description properties, see Properties Common to all Activities.

## Connectivity Requirements

This activity works when the device has intermittent connectivity to the network.

## Version Information

Supported from: Geocortex Viewer for HTML5 2.9, ArcGIS Web AppBuilder 2.4.
