I have a set of Rain Gage Thiessen polygons where I would like to test for the IDs that are in a certain area. The areas of the Thiessen polygons and the underlying areas overlap, so there are instances where a Rain Gage may need to go to multiple output ports for further calculations.

TestFilter uses If...Then so if I test for RG #6 to go out output port 'A', I am assuming that it will never go out port 'B'.

One solution is to connect the input ports to multiple Testers in parallel. This ensures that RG #6 goes to both areas. This works but I'm trying to see if there is a transformer or more efficient process where a single input record can go out multiple output ports.

Thanks!

Could you use the Conditional values option in the AttributeCreator to do different calculations based on test clauses?

Then define when this calculation is used

if you are spatially relating the polygons you can use the resulting attribute (_overlaps if using the areaonareaoverlayer) in the if then else statements in the testfilter which supports your own defined output ports.

So for example if a gage only overlaps with one area (_overlap =1) and the #RG is 6 the create output port 1, if it relates to two areas then create output port 2 and so on.

Hi @mikeszwaya, How did you determine that, for example, the #6 rain gage is related to the two areas - A and B? I think the SpatialRelator and ListExploder might help you depending on the data condition and your requirement.
