Cultural Landscape

The visible imprint of human activity on the physical landscape, shaped by culture (religion, language), economy, and physical geography

Formal Region

A region in which everyone shares one or more common characteristics, such as language, religion, or government (also called a uniform region)

Functional Region

A region organized around a central node or focal point, connected through transportation, communication, or economic systems (also called a nodal region)

Vernacular Region

A region that people believe exists as part of their cultural identity, based on shared perception rather than official boundaries (also called a perceptual region)
