Hello,
I have a network of (+) intersecting lines (There is no (T) intersections). I have also nodes of these + intersections also extracted.
I want that whenever there is an intersection, the shortest line to be splitted to 2 lines but the long ones remains as it is
Can anyone help me with this ?
Thank you very much
Hi @lianaolianov
Could you share us your workspace template?
Thanks,
Danilo

Sorry for late reply and thank you :)
1) get the length of your lines by using a LengthCalculator.
2) Use a SpatialRelator and set 'Accumulation mode' to 'Merge Attributes'. Use the nodes as requestor (and make sure they have a unique id) and the lines as supllier.
3) Then use a TestFilter to compare the 2 length attributes (which should be added to the node they intersect) to see which line is the longest for each node.
4) For the shortest lines: use a PointOnLine overlayer or Intersector to split them into two segments.
5) Use a FeatureMerger to recover the longest lines from the original dataset based on their ID.
Without seeing the data I am not sure if this would cover your question completely, but it can give you a direction on how to start.

I am following the steps, but actually I get just One length attribute per node, how do I get the two separately ?

I solved the problem by creating a list and exposing the two lengths as attributes
