Is there a way to sink a ditch/furrow with a trapezoidal cross section following a line in a DEM?
Hi, I have a DEM with 25cm resolution and I would like to sink a ditch/furrow into the DEM. The ditch has a trapezoidal cross section, each side of the ditch has 2 different angles of slope. I already have a line representing an existing pipline and I want to sink the ditch into the terrain along the existing pipeline. I need to be able to define the slope, depth, width of ditch etc. I see the Terrain Painting tool has something approaching what I want except I would like to select an existing line and not digitise with the "brush" and also I need to be able to define the dimentions of the ditch. I am using Global Mapper v22.1.1. Thanks very much. Mark
