|
Parameter |
Description |
|
SpatialReference |
The spatial reference of the geometries in the InGeometryArray. This cannot be null. |
|
InGeometryArray |
An array of points, multipoints, polylines or polygons. The input types cannot be mixed. |
Return Value
A single Geometry of the same type as the inputs.
Remarks
This operation constructs the set-theoretic union of the geometries in the input array. All inputs must be of the same type.
