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.

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

Measurement unit of the distances.

Defaults to the units of the input geometries.

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.

Outputs

geometry

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