Hello, new to FME here and am looking for some advice on which transformers might work for a workbench that I am trying to create. I have 2 road line feature classes stored in an SDE geodatabase. The lines store similar information but are created and maintained by two different departments (they have different road name standards and the geometry does not match). I would like to compare the lines and identify which ones from Roads_A are missing from Roads_B.  

My main concern at this point is identifying missing subdivisions like the one in the screen capture below.

 

Hello ​@srijneke , how are you?

 

I suggest you the use the transformer ChangeDetector.

 

Thanks in Advance,

 

Danilo

 

 

This thread may be useful to you, there are a few approaches mentioned utilizing bufferer, neighbor finder, or fuzzy parallel line finder:

 

Yes, thank you I saw that post as well. I was hoping fuzzy parallel line finder would work but I can’t seem to get the inputs right. As far as I can tell, all it did was append the two datasets together. I didn’t see an attribute that indicated which lines were the same or different.
