On small to medium scale maps, relief is often represented with semi-pictorial symbols. What is this map type called?

• A. Isoplets
• B. Isopach Map
• C. Isopleths
• D. Planimetric Map

Answer: (A)

Smaller-scale maps often convey terrain using semi-pictorial relief symbols arranged along lines of equal value, a style known as an isoplet map. These maps use pictorial hill cues and shading rather than dense contour lines to give a quick sense of relief, keeping the map readable at limited scales. The term isoplet (a variant of isopleth) specifically describes this approach of grouping by equal relief value while employing pictorial symbols to represent terrain. The other options refer to different concepts: an isopach shows thickness, a planimetric map displays features with no height information, and isopleths are lines of equal value in a broader sense but not the semi-pictorial relief style described here.
