A Spatial Multicriteria Assessment Decision Support System (Smca-Dss) For East Naples: Towards A Water Opportunity Map

The objective of this study is to present the methodological process for the elaboration of a Spatial Multicriteria Assessment Decision Support System (SMCA-DSS) oriented to the definition of a Water Opportunity Map for a Naples Eastern Area, in Italy. The proposed approach extends the formalization of multicriteria methods and social network analysis in Geographical Information Systems (GIS), including spatial structure and temporal dynamics. The combined application can be useful in spatial decision making process for urban planning, supporting and modelling operations for urban land-use change. Analysing the opportunities for the storm-water management, the paper explores possible shared scenarios of transformations identifying the main effects on the local context.
