Creating Map Symbology

Have you ever noticed that some maps are easier to understand than others? Often, the difference is due to the mapmaker's choice and arrangement of symbols and text. A map is most effective when its symbols are easy to distinguish and their meaning is intuitive.

Your choice of symbols and labels will be influenced by the type of map you are making. Maps can be divided into two main categories: reference maps (also called general maps) and thematic maps. Reference maps show the location of features and are useful for multiple purposes—atlas maps and topographic maps are examples of reference maps. Thematic maps show the structure and distribution of one or more phenomena. Examples of thematic maps include maps of world population, today's weather, and rice production in the Philippines.

In this session, you will practice a variety of techniques for choosing and modifying symbols and text for both reference and thematic maps. We will revisit the art and science of creating thematic maps at the end of the semester.
