“People reading categorical thematic maps should gain an understanding of overall patterns and relationships among different kinds of geographic phenomena.  The main objective of a categorical map is not to present an inventory of individual features, as is the case with many special-purpose and reference maps. Base information on thematic maps helps map users compare characteristics of their home or a place of particular concern to the patterns evident in the map theme” (Brewer 2008, 103).
