Merge two line feature classes with similar / the same course

Hi Dani,

I can think of a few different approaches to take:

• Since these are from different sources, you can use the ChangeDetector to try and identify matching lines.
• You could create new geometry by putting a buffer around each line and dissolving those buffers together where they overlap. Then use the CenterLineReplacer to generate new centre lines.
• The Displacer transformer is meant for situations like this, where you want to ensure a certain separation between features. I think you could probably use it and then just drop/ignore the Displaced features.

I’d be tempted to try the Displacer first, but any of these approaches could work. I don’t think there is a standard method or specific transformer - but I would not be surprised if other users have different ideas!

Adding to @mark2atsafe’s list, I would recommend looking into the AnchoredSnapper as well.

Hello together

First of all, many thanks for the great support.

@mark2atsafe: I like that you show different approaches :-). I have also tried the buffer solution in ArcGIS Pro, but it became too confusing and I wanted to keep one of the lines and not draw a new line (would probably also work via a SpatialJoin). I think the Displacer could work, but the solution from @ctredinnick sounded exactly like what I was looking for. 

I tried the transformer with different buffer distances and 50 m worked the best for me. Also I had to take the watercourse with the samller and more frequent segments as the requestor and I’m very happy with the solution :-).

Thanks again and best regards
Dani

Nice one, @ctredinnick - I had no idea that transformer existed, but I love it when there’s a perfect solution that already exists like this! For creating that great transformer, you’re awarded the FME Star badge!
