Qualitative thematic maps display descriptive (nominal) data such as the locations of particular features on a base map. Examples include maps showing the locations of public facilities in a municipality, the locations of Provincial capital cities, maps of ski resorts, road maps, maps showing the principal rivers of a region, geology maps, soil maps, vegetation maps, and so on. If the features in question are at precise points, at the scale of the base map (such as the location of a house on a 1:50 000 map), they can be shown by a nominal point symbol. For example, a house might appear as a round or square dot, Christian churches in a region might be depicted by small crosses, locations of fishing resorts along the coast might be shown by a small fish symbol while campgrounds might be marked by a small tent symbol. In Figure 9.1 nominal point symbols are used to locate particular types of mineral resource developments in Canada .
