Hi all

I have the edges of a road and want to be able to measure the distance between the two edges perpendicular to the left hand edge at a distance every 10 metres.

Any suggestions on how to complete this as I can not get my head around it.

Thanks in advance.

Hi @ingalla

I would suggest to use the IterativeSnipper to generate a point every X distance for both lines and then use the NeighborFinder to find the closest point of the other line. The NeighborFinder also returns the distance to this point.

I agree with @jeroenstiers. I'll just add that if you have a common ID on both road edges, I'd recommend using those as a Group By for the NeighborFinder. This will avoid a lot of problems in e.g. intersections.
