In this case, larger circles represent taller cellular towers. Choropleth Contour (Isoline) Categorical Major roads Counties Major cities and towns Capital Reference maps A reference map shows the location of specific features such as roads, cities, and streams. Types of reference maps include political maps (locations of countries, states, cities), physical maps (locations of streams, lakes, mountains), topographic maps (natural and human-made features), and road maps. Thematic maps A thematic map focuses on one specific topic or theme. Thematic maps are either qualitative or quantitative. Cellular towers per square mile, height of cellular towers, and elevation contours are examples of quantitative maps with numeric values. The categorical map of cellular phone service is an example of a qualitative map where values are non- numeric. See the glossary for more types of thematic maps. Wyoming reference map Four types of thematic maps Different shades of color represent ranges or classifications of numeric values applied to predefined areas, such as counties. See data classification entry in glossary. Isolines joining points of equal elevation are called contours. The interval for this elevation map is 500 meters. Isolines can also be used to map many other continuous types of data. By combining cellular tower heights with ground elevation, we can derive categories where cellular service may be available and areas that are “out of range.” Cellular towers per 500 square miles Fewer than 1 1.0–1.5 1.6–2.0 2.1–2.5 More than 2.5 Elevation (meters) 1500 2000 2500 3000 3500 4000 Cellular service Available Unavailable Cellular tower height (feet) Under 10 10–30 31–50 51– 80 Above 80
