Description
Creates buffer polygons at a specified distance around the input geometries.
Usage
You may need to buffer around a geometry. A common scenario is to first buffer around a feature using the Buffer Geometry activity, and then use a Query Layer activity with the buffered geometry as an input to find out what is near the feature.
Inputs
Url |
Required Type: String The URL of the ArcGIS geometry service. For example, https://utility.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer. |
Geometry |
Required Type: esri.Geometry (3.x, 4.x)* | esri.Geometry[] (3.x, 4.x)* The geometries to buffer. |
Distance |
Required The distances the input geometries are buffered. |
Unit |
Optional Type: "meters" | "feet" | "kilometers" | "miles" | "nautical-miles" | "yards" | String The units for calculating each buffer distance. If units are not specified, they are inferred from Buffer Spatial Reference. If Buffer Spatial Reference is not specified, units are derived from the features being buffered. |
Buffer Spatial Reference |
Optional Type: Number | String | esri.SpatialReference (3.x, 4.x)* The spatial reference in which the geometries are buffered. If Buffer Spatial Reference is not specified, the geometries are buffered in the spatial reference specified by Out Spatial Reference. If Out Spatial Reference is also not specified, they are buffered in the spatial reference of the features. |
Out Spatial Reference |
Optional Type: Number | String | esri.SpatialReference (3.x, 4.x)* The spatial reference for the returned geometries. If Out Spatial Reference is not specified, the geometries are output in the spatial reference specified by Buffer Spatial Reference. If Buffer Spatial Reference is also not specified, they are in the spatial reference of the features. |
Geodesic |
Optional Type: Boolean If the input geometries are in geographic coordinate system, set geodesic to true in order to generate a buffer polygon using a geodesic distance. |
Union |
Optional Type: Boolean If true, all geometries buffered at a given distance are unioned into a single (possibly multipart) polygon, and the unioned geometry is placed in the output array. The default is false. |
* 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
geometry |
Type: esri.Polygon (3.x, 4.x)* The first buffer result. |
results |
Type: esri.Polygon[] (3.x, 4.x)* The buffer results. |
