Urban Heritage Regeneration in the Old Town of Ragusa (Italy): An Architecture-Centred Analysis-Valuation-Plan Pattern

The old town of Ragusa is undertaking a regeneration process in some different directions. Its differently valued areas need to be comprised in a whole valorisation strategy, connecting the decision making process with functional and symbolic values. In such a multi-layered urban sub-system, the architectural unit can play the role of one of the main information/value units which the valuation/decision making pattern starts from. The pattern works as an impact assessment tool, that generates a great number of intervention strategies in order to maximize different and conflicting objectives, and provides for each of them an axiological profile aimed at defining a trade-off scheme between them. Some GIS tools and a WebGIS interface allow the real-time control of the differentscenarios envisaged in the decision making process.
