A Complex Values Map of Marginal Urban Landscapes: An Experiment in Naples (Italy)

The paper seeks to highlight how the character and values of marginal landscapes can be considered examples of the “third landscape” and how they can enable the mapping of tangible and intangible change (and its relative effects) through the selection of appropriate spatial indicators. A Dynamic Spatial Decision Support System was constructed to help identify the complex values characterizing a selected area in Naples’ marginal urban landscape. The System consists of a set of selected indicators that represent the area’s distinguishing characteristics with specifc focus on its critical and potential factors. The formulation of spatial indicators helps identify the ecological, socio-economic and urban characteristics of the case-study area, along with their historic evolution over a specifc time period. Time History Analysis (THA) enables the identifcation of permanent elements and transformations along with the relationships among the various urban land-scape components over time. The synergistic interaction between the appropriately structured Geographic Information System (GIS) and the multi-criteria Analytic Hierarchy Process (AHP) method help to generate a complex values map of the analyzed landscape to support the defnition and location of strategic actions.
