Hi,
I don't understand the shortestpathfinder.
I want to achieve the following:
I have a layer waternetwork (VHA) and used the topologybuilder to create end and beginnodes.Then i have 2 other layers,1 with de beginpoints (from) and another layer with endpoints.These points are exactly on the watercours.For each beginpoint,i want to know the lines in the waternetworks to come to the specified eindpoint and calculate the length.
I wanted to use the shortestpathfinder but i have no outcome.First i have used de custom from/to transformer where i connected the beginpoint tot from and the endpoints in to,but again no outcome.
The same with the shortestpath finder.I know i'm doing something wrong but i don't know which parameters to use of what to do.
Does anyone have an example of how to set up the transformer correctly?
Thx
Nathalie
The most important part is that the ShortestPathFinder expects aline featurein the From-To input port.Have you verified that?
Here's a couple of short videos that demonstrates the transformer:
Hello,you could try splitting the network with the points (PointOnLineOverlayer) before building the topology.Owen
