Which term refers to a relief-drawing technique using curves?

• A. Tick
• B. Vertical exaggeration
• C. Transverse projection
• D. Trachographic relief drawing

Answer: (D)

Curve-based relief drawing expresses terrain with curved lines that trace the shape of the land. By layering these curves, the map communicates elevation and slope: where lines are dense and bend sharply, the terrain is steeper; where they are spread apart, the land is gentler. This approach is called trachographic relief drawing, because the emphasis is on using curves to depict relief. It differs from tick relief, which uses simple marks; vertical exaggeration, which changes the vertical scale rather than the drawing method; and transverse projection, which is a way of projecting terrain rather than a curve-based depiction technique.
