L'analisi archeologica nei processi di valutazione ambientale,. Proposta metodologica in ambiente GIS

This paper illustrates a research project aimed at testing a method of GIS-based evaluation which was conducted using specific criteria and an "objective point of view" during an archaeological impact assessment. The authors tested the use of a database, linked to a GIS platform, to assign fixed values in order to evaluate the "potential", the "value of the context" and the "risk" of single archaeological sites affected by new projects of urban development. Based on the application of the same methodology and language used by the scholars involved in the environmental impact studies and coming from other scientific fields (natural sciences, economics, etc.), the assessment idea is proposed in order to stimulate archaeologists to use not only qualitative, but also quantitative values, like the procedures for the environmental impact assessment. Some case studies relative to the Venetian Lagoon, Mestre and Comacchio (FE) conclude the paper
