Description:

Uses the ArcGIS Geometry Service to union a collection of graphics.

Inheritance Hierarchy:

System.Object
  System.Activities.Activity
    System.Activities.AsyncCodeActivity
      Geocortex.Workflow.Activities.UnionTask

Function:

This activity unions a set of geometries and then returns the resulting geometry (the union of all the geometries in the input collection).

In a Workflow:

A Union activity could be used after performing Buffer Geometry activity on features in separate layers. The union activity would then be used to combine the 2 areas of the separate buffers into a single geometry.
