Symbology

Definition

Symbology refers to the use of symbols and visual representations to convey information and data in a clear and understandable manner. In mapping, symbology plays a crucial role as it determines how different features are visually represented, such as using colors, shapes, and patterns to distinguish between various data points or geographic areas. Effective symbology enhances the readability and interpretability of maps, helping viewers quickly grasp complex data relationships.
