Kilometer Point values and Distance-Off-Line values of a point file (referenced to a route line)
Can anyone help me on this one???
I have a line file representing the route of a cable. I have generated "Kilometer Point" flags along the line and labelled it every kilometer (i.e. the chainage). I have a point file representing thousands of items scattered along the locality of the route. I need to generate an attribute for every point showing the distance away from the line that it is (i.e. "Distance-Cross-Course" or "Distance-Off-Line"). The value should be negative when the point is to the left of the line (looking along the line) and positive when it is to the right of the line. I also need to generate an attribute for every point showing the KP that it falls on, if a line is drawn through the point and perpendicular to the route (i.e. its KP value when projected onto the route).
Does anybody have an easy way (or any way???) of doing this please.
Many thanks indeed
