Altered Landscapes

Hartshorne differentiated the term from region which he considers is larger and more flexible in size. He eliminated sky on the basis that the atmosphere is simply the medium through which the Earth's surface is viewed and also excludes underground mine workings, the soil beneath vegetation and rainfall. However he included moveable objects noting that a view of Broadway (New York City) without traffic would be incomplete. He ignored the inclusion of oceans in landscape. He opposed perception of landscapes by other than sight, e.g. sounds and odours, on the grounds that these do not contribute to a unified concept. In regard to the concept of natural and cultural landscapes that Carl Sauer among others differentiated, he stated "the natural landscape ceased to exist when man appeared on the scene". While admitting the term primeval landscape could refer to pre-human landscapes he considered the present natural landscape is "a theoretical concept which never did exist".
During the 1920s and 1930s, attempts were made to construct methodologies that made landscape the essential if not exclusive task of geography. This stemmed from Sauer's view that the role of geography was to systematically examine the "phenomenology of landscape". Sauer viewed landscapes broadly as areas comprising distinct associations of forms, both physical and natural, and regarded landscape study as tracing the development of natural landscapes into cultural landscapes.
By the 1940s, this emphasis had passed as geographers found that the difficulties associated with reconstructing the past were forbidding and at odds with their primary concern with the present world. The concept of a natural landscape became increasingly questioned with knowledge of human impact on the environment. More recent geographers have addressed the subjective attributes of a place within humanistic geography thus crossing the bridge between the objective and the subjective assessment of an area.
The popular conception of the landscape that is reflected in dictionaries conveys a particular and a general meaning; the particular referring to an area of the Earth's surface and the general meaning being that which can be seen by an observer.
