What is meant by 'symbolization' in mapping?

Symbolization in mapping refers specifically to the use of symbols to convey information on a map. This involves representing various features, attributes, or categories using graphical symbols, such as icons, colors, shapes, or lines, which makes it easier for map users to understand and interpret the data being presented. For example, different colors might be used to represent different types of land use, while symbols can indicate locations of schools, hospitals, or parks.

This method is crucial because it allows for the visualization of complex information in a concise manner, enabling viewers to quickly grasp the significance of the data without being overwhelmed by numerical information. By effectively utilizing symbolization, maps can present a wealth of information in an intuitive and accessible format, which enhances the overall function of the map as a tool for understanding spatial relationships and geographic contexts.
