In answer to your question I am trying to give you what I know through a bibliography on the landscape studies.
Whatever the methods used, landscape analysis remains an indispensable tool in the planning. It provides insight into the structure of space. It also aims to reconstruct the links between landscape elements, to offer a diagnosis of the current state and propose a prediction of the future state based on the relationship that we have successfully identified and knowledge of the history of the site. It is based on three approaches:
- Approaches that rely solely on the value system of socio-cultural individuals and their own experience with the landscape seen regardless of spatial data.
- Other approaches based exclusively on landscape criteria in view of the visual aspect.
- As to the latter category of approach that best meets the landscape concept puts in direct relationship with the landscape observer who seeks to understand the relationships between the shapes of the landscape and its social representations. The last two approaches require knowledge of the landscape and use methods of analysis both quantitatively and qualitatively.
