Greenweb in Land Enhancement Policy of Enna Province - A DRSA Valuation Pattern in WebGIS Interaction Practice

Abstract:

The Enna Province is characterized by a low degree of economic, infrastructural and industrial development. Its hilly territory is a fair combination of many different and integrated landscapes. These conditions suggest the possibility of a sustainable development pattern in which the slow mobility, because of the low level of land infrastructures, can become one of the most important network for the land-value communication.The study applies an axiological approach, useful for the subsequent land planning practice, including a qualitative valuation model and an interactive multi-criteria tool combining Web-GIS and DRSA (Dominance Rough Set Approach) patterns.The valuation model is based on an axiological square in which four kinds of appreciation are taken into account. A WBS pattern explains in detail each appreciation, so that every piece of the green-web can be characterized and assessed within a general framework oriented to provide the aggregate value of the path to which they relate.The DRSA tool is used to generate the preferences structure of the target segments users. It is used as basis for extracting and the processing data. It allows to identify the preferences structure to support the WebGIS tools to generate the green way that best meet the user’s preferences.
