The present paper explores the spatial distribution of soil sealing in Italy through multivariate statistics and spatial analysis. Methods and Results Based on a high-resolution land-use map, a "sealing profile" was determined for each travel-to-work area by analysing the distribution of land occupied by 12 classes of imperviousness using a Principal Components Analysis. Two indicators of soil sealing have been developed (sealing intensity and per capita sealed land) and the investigated districts have been classified accordingly. Different urbanization patterns have been identified based on population density, the district economic structure and infrastructure at the local scale. Conclusions The study indicates the transition from a mono-centric and more compact urban form to a polycentric and dispersed agglomeration with implications for urban containment policies and environmental monitoring strategies
