+1Hello, i used the topologybuilder transformer to build the topology of a network ( roads centrlines).
The problem is that z values are not considered while computing intersections. So it may not produce correct results for overpasses, inderpasses....
Any recommandations please. Thank you.
+58Which is as the documentation states: "Though Z values (elevations) will be retained on features, they are not considered when computing intersections."
So you should find a way to exclude the overpasses, underpasses... (maybe by some attribute? maybe by it's Z-values? maybe something else?)

if I exclude them before the transformer, it is not possible since the transformer will create a node each time there is an intersection, if I exclude them after it will destroy the topology created since the identifier of the node and the edge has already been considered in relations with other entities.
