Display Capture Geometry Activity

Description:

Displays a form with a toolbar that allows you to select a geometry based on the configured allowable geometry types.

Inheritance Hierarchy:

System.Object
  System.Activities.Activity
    System.Activities.NativeActivity
      Geocortex.Workflow.Activities.ExternalActivityBase
        Geocortex.Workflow.Activities.DisplayCaptureGeometry

Function:

Allows the end user to define a geometry by selecting from a few different geometry types (point, polygon, etc.), with the allowable types defined by this activity.

In a Workflow:

A workflow could allow the user to choose to extract features within a certain area of interest. This activity could be used to collect that area of interest, where the user can choose between defining the geometry using a rectangle, polygon, or the current extent.

Properties:
