I have a shapefile (polylines) of some roads and I want to divide the roads in ramps.
Ramp = a piece of the road delimited by the top of a hill and a valley.
So, pretending that you're driving in these roads, when you're going up you have one polyline for this part of the path, when you start going down you have another polyline of this path.
I have the Digital Elevation Model of the area, which I made using the "Topo to Raster" tool from "Spatial Analyst". To make it I used the shapefile of the rivers (stream), the limit (boundary), the point elevation and the contour (10 meters)
I found a set of tools called ET Surface and what I need is exactly what the tool "Split PolylineZ based on slope direction change" does, but I don't have the licence to use it.
