I'm attempting to calculate the relative height (values between 0 and 1 preferably) of waypoints on a slope along the path of least resistance. Ideally, points in creeks would have values of 0 and points on ridges would have values of 1 (or opposite values would also work). I have about 200 waypoints that I need to do this for and will need to do it manually otherwise. I'm using ArcMap version 10.1.
To clarify, I have waypoints in mountainous terrain and I need to know the change in elevation that water will likely flow from the top of the ridge. I would also like to know the change in height from the same waypoint to the point where it will intersect the nearest creek. I will manually calculate the ratio of the difference in height from the waypoint to the ridge vs. the overall change in height in order to get a ratio of the height of water flow to the overall height of the water path before intersecting a creek. It would be nice if there was a tool that already did this.
