The field of geography relies on many different types of maps in order to study the features of the earth. Some maps are so common that a child would recognize them, while others are used only by professionals in specialized fields. What Is a Map? Simply defined, maps are pictures of the Earth's surface.
These maps show a large area, complete with its economic regions, territorial-production complexes, economic centers, economic ties, levels of economic development and specialization of production. Economic maps may also feature labor resources and natural resources as components of economic activity.
A thematic map is a map that emphasizes a particular theme or special topic such as the average distribution of rainfall in an area. They are different from general reference maps because they do not just show natural features like rivers, cities, political subdivisions and highways.
