I have polylines that have Z coordinates on each vertex. The polylines represent water pipes and are below the ground surface ~1 meter. I have a LAS of the ground surface which can be converted to a raster to create a surface. The situation can occur where the polylines get above the ground surface in between the vertices due to variation in terrain and lack of vertices with X, Y, Z values in the polylines. How can I identify those locations and add an extra vertex so the polylines will stay below the ground surface?
