"A thematic map is a type of map that portrays the geographic pattern of a particular subject matter (theme) in a geographic area."
Incorporates data on a specific theme, such as population density, vegetation, or transportation routes.
"They contrast with general reference maps, which focus on the location (more than the properties) of a diverse set of physical features, such as rivers, roads, and buildings."
"Alternative names have been suggested for this class, such as special-subject or special-purpose maps, statistical maps, or distribution maps."
"Thematic mapping is closely allied with the field of Geovisualization."
"Several types of thematic maps have been invented, starting in the 18th and 19th centuries."
"A wide variety of phenomena and data can thus be visualized using thematic maps, including those from the natural world (e.g., climate, soils) and the human world (e.g., demographics, public health)."
"This usually involves the use of map symbols to visualize selected properties of geographic features that are not naturally visible."
"...temperature, language, or population."
"These types, such as choropleth maps, isarithmic maps, and chorochromatic maps, use very different strategies for representing the location and attributes of geographic phenomena."
"...each is preferable for different forms of phenomena and different forms of available data."
"Choropleth maps, isarithmic maps, and chorochromatic maps..."
"...starting in the 18th and 19th centuries, as large amounts of statistical data began to be collected and published, such as national censuses."
