Slice waterfall view window showing roads, cutting, benches and drainage between roads
The waterfall view contains many visual clues about the map. It is generated from multiple cross-sections each spaced an equal step apart and displayed slightly offset on the screen. This example also has a vertical scale exaggeration of six times the horizontal.
The yellow lines represent almost vertical sections. As the elevation (RL) changes so does the color of the lines. The section on top of the benches is a different color to that of the surrounding due to its increase in elevation. The roads are in red.
