Project Single Geometry Task Activity

Description:

Applies a geographic projection to a single geometry using the ArcGIS Geometry Service.

Inheritance Hierarchy:

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

Function:

This activity takes a single geometry and applies a geographic projection onto it. You can use this activity to transfer a geometry between projection systems.

In a Workflow:

If a geometry is in a specific projection for the area your business focuses on, but you then need to access a layer or service like geocoding that covers a different geographical region, using a different projection, you could use the Project Single Geometry Task activity to convert the geometry to your operation projection.
