Which term describes showing relief on small to medium scale maps using semi-pictorial symbols?

Isopleths are lines that connect points of equal value, such as elevation, and on small to medium scale maps they offer a clean way to show relief with semi-pictorial cues rather than dense, detailed contours. This approach keeps the map readable while still conveying the terrain’s form; the lines summarize gradual changes in height, and accompanying small symbols or shading along or between the lines can suggest hills, ridges, and valleys without overwhelming the map. Contour lines would emphasize precise elevation steps and can clutter a smaller map; elevation refers to the measurement itself rather than a depiction method; relief mapping is a broad term that doesn’t specify the line-based, semi-pictorial technique used here.
