+5Hi,
I'm trying to create a shortest path from point A to B, yet FME is not outputting any path. I've looked at similar questions asked on here, and I've adapted my workbench accordinly, but still no luck.
I'm using an OpenStreetMap highway layer as input. I've explicitely set my snapping tolerance as relatively high in the shortespathfinder, just so that I could just get some output. But it didn't work either.

For some reason I've had much better results using a stand-alone Snapper before building the topology, rather than relying on the ShortestPathFinder tolerance.
+19Weren't no features output from the "NoPath" port?
If all network lines don't belong to a single connected network, there could be no path between specified from-to. You can use the NetworkTopologyCalculator to check if the lines belong to a single network.

And how would this whole "shortest path finder" process with the same parameters (by lenght, by costs etc) be accomplished with raster data?
