I have a list of things each have two grid references, start and stop points. I can turn these into points and join them with polylines.
But what I need to do is have the lines that join the points the follow the route of another polyline, in this case it is a river.
I have 38 lists (for various rivers), each with 10-20 items on them, so hopefully I can find a quick soloution.
