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.

Your
choice of symbols and labels will be influenced by the type of map you are

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

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.
