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 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. |
* 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.
