Hi,
i tried to merge multiple lines into only one line, but the difficult is, that also connected lines on a course between start- and end-Point should be merged into the "one line"
with linejoiner the lines were only merged until the next Connection.
has anyone an idea?

Hi @sebastiangoerck, you can transform them into a single MultiCurve (IFMEMultiCurve) geometry using the Aggregator transformer.
:-) sometimes it is so simple, thank you!
no i have Aggregate it, but the next step is to deaggregate it, by endnodes.
any idea?

Have you tried to use the group by setting in the aggregator? that will aggregate your features per group.
i have connected the endnode Reader to the aggregator, then i have tried to Group by endnode Name, but the result is not that what i expect.
the Count of objects were 5 but in the inspector were one highlighted

the attributes were separated by the endnode names

Deaggregating by Endnode..You should be able to do it with a TopologyBuilder.
One more thing, if you want to deaggregate by spatial connection, you can do it as follow:
I hope it helps.

Hi, topologybuilder was the right transformer...thanks
Hi,
I think,
the first step should be "NetworkTopologyCalculator". It is connecting to the lines and it is creating "_network_id".
the second step should be "Aggregator" (group by: "_network_id")
Hi,
I am in the same situation as the one initially described by you and I saw that you found a solution, but I did not manage to solve it using everything that was written here.
Can you describe to us all the steps taken to create a single line
Thank you
hi,
as "esaka" wrote is the "NetworkTopologyCalculator" the right Transformer. It create the "_network_id". then you can use this to aggregate or something else.
otherwise you have to explain your issue more detailed.
Yes, it is a very good solution and it works great. The problem I encounter is that after the aggregator, IFMEMultiCurve type lines result.
What I would like is to result in a polyline that I can store in the poistgis database.
Or maybe I could also store this result in the database, but I don't know how.
Thanks a lot

Hi @alain2002 you could try using the GeometryCoercer transformer to change the geometry type to fme_line.
