Union Two Geometries

Essentials 4.3.0  HTML5 2.4.0

 

I have two geometries - the results of two Union activities.  Now I'd like to Union these two geometries together, but they are not in a FeatureSet.  Do I have to create a new FeatureSet and add these two geometries to it?  If so, how do I do that in a Workflow?  Or is there a way to just create a new geometry that is the union of these two?  The Geometry Service has a Union function, but I'm not sure how to call this in a Workflow.

 

Any help is appreciated.

 

Thanks.

  Hi Sean,

   

  Get ready for a nice one liner! Put this into the featureset argument of the UnionTask:

   

  New List(Of Graphic)({new Graphic With {.geometry = unionGeometry1}, new Graphic With {.geometry =unionGeometry2}})

   

  Replace unionGeometry1 and unionGeometry2 with the ones from the previous unions.

  That sure beats the Create List->Add List Items->Convert List to FeatureSet->Union sequence I made.  Thanks for the one-liner.   Here's a one-liner in return:

   

  You will never persuade me to change my behavior simply by convincing me it is ridiculous.

   

  Hope that helps.  Cheers!
