Analytical method for environmental data representativeness of a territory

The description of the environmental conditions of an area is often done by using modeling programs. Its validation requires a significant number of background values, representative of the real state. These data are also necessary for the proper management of environmental issues in relation to different causes of present pollution. The sampling of these values, moreover, requires the execution of measurements characterized by a burden of cost and time. For this reason the possibility to take in advantage the existing background's environmental data, collected from studies conducted in the past, is a great resource base for the qualification and land management. However, historical data are characterized by heterogeneity in format and content and are liable to risk of obsolescence due to changes over time in the context. This research proposes a methodology of processing the historical documentation (when present) in order to obtain homogeneous data, comparable with one another and representative of the current conditions of the territory. These results, jointly with the analysis of the environmental context, are also aimed to the design of additional measures necessary for the completion of the scoreboard. The method was applied to the noise and airborne particulates risk factors.
