ShortestPathFinder

Computes the shortest path of a line or lines containing a source and destination node in a network based on the length of the input or the cost (specified in an attribute) of each of the edges.

Usage Notes

If ShortestPathFinder produces unexpected results, consider using AnchoredSnapper instead. Input the From-To Line through the Candidate input port and use the same value for Snapping Tolerance. Specify Snapping Type = End Point Snapping and Add Additional Vertex = NEVER.

Only linear features with non-negative cost attribute values are allowed if the Cost Type is set to By One Attribute or By Two Attributes. If a feature does not have the attribute specified in the Forward Cost Attribute or the Reverse Cost Attribute, a zero cost is used for the line. Any features with a negative cost will be output through the <Rejected> port.
