Buffer Geometry Activity

Description

Creates buffer polygons at a specified distance around the input geometries.

Usage

You may need to buffer around a geometry. A common scenario to use a Buffer Geometry activity is to first buffer around a feature. Then use a Query Layer activity with the buffered geometry as an input to find out what is near the feature.

Offline Support

This activity works when the device is offline.

Inputs

Geometry

Required

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

The buffer input geometry.

Distance

Required

Type: Number | Number[]

The specified distance(s) for buffering.

Unit

Optional

Type: "meters" | "feet" | "kilometers" | "miles" | "nautical-miles" | "yards" | String

Measurement unit of the distances.

Defaults to the units of the input geometries.

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

Geodesic

Optional

Type: Boolean

Whether to use a geodesic buffer or a non-geodesic buffer.

Union

Optional

Type: Boolean

Whether the output geometries should be unioned into a single polygon.

* Geocortex Workflow uses different versions of Esri's ArcGIS API for JavaScript depending on the type of application. Web AppBuilder 2D apps and Geocortex HTML5 viewers use version 3.x of the JavaScript API. Web AppBuilder 3D apps use version 4.x.

Outputs

geometry

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

The first buffer or result (or the union result).

results

Type: esri.Polygon[] (3.x, 4.x)*

The buffer results.
