Which term refers to the use of different symbols for points on a map?

The correct term for the use of different symbols for points on a map is often referred to as "shape." In cartography and geographic information systems (GIS), symbols play a crucial role in representing various features or data points on a map. The shape of these symbols helps convey information about the nature of the data they represent.

For example, different shapes can be used to represent schools, hospitals, or parks, providing viewers with immediate visual cues that inform them about the types of features present in the area. The distinct shapes allow for easy differentiation and classification of features, enabling users to interpret the map quickly and effectively.

In this context, hue, which refers to the color aspect, and pattern, which deals with the arrangement of symbols, while significant in map design, do not pertain specifically to the use of varied symbols for points. Visual contrast relates more to the differences in visibility between elements instead of the fundamental concept of symbol shapes themselves. Thus, "shape" is the most accurate term for the question asked.
