Union Dialog

The spatial operation union dialog window allows the user to union one or more feature geometries. Union returns a feature set that represents the point set union of the input features. You can think of this as the merging of all input features into a single output feature. In other words, the union combines all the input geometries into a single output geometry.

The dialog controls are:

• Union The Features In Layer
  
  A dropdown list box that contains a list of geometry datasets in the active Map View window.
• Features To Union
  
  A dropdown list box that specifies what features in the selected layer to process.
• Please Specify The Results File Path
  
  The file path that specifies the location of the output results file.
• File Path - Browse
  
  When this button is clicked a file save dialog is displayed for the user to select the file path and file name of the output results file.
• Title
  
  A text string that will be displayed in the Task Pane window to help uniquely identify the task.
• OK
  
  When this button is clicked the dialog queues the Union task with the Parallel Processing Server and closes the dialog. Use the Task Pane window to monitor the task progress. A popup balloon window and the Task Pane will alert the user when the task is complete.
• Cancel
  
  Closes the dialog window.
