Which method uses curve hill shaped lines to indicate relief on small maps?

• A. Stereoscopic Vision
• B. 3 Color Process
• C. Trachographic Relief Drawing
• D. Scribing

Answer: (C)

The idea being tested is depicting terrain on a small map using curved lines that imitate hill forms. Trachographic Relief Drawing uses a network of curved, hill-shaped lines to convey elevation and the shape of the land, rather than relying on shading or color. By adjusting how tightly the lines curve and how close together they are, this method communicates differences in height and slope on a compact map. It’s especially useful when map size is small and other relief techniques are impractical. The other options don’t fit because stereoscopic vision relies on two images to create a 3D effect, the 3 Color Process focuses on color reproduction, and scribing involves engraving or scratching lines, not the specific curved hill-shaped contour style used in this method.
