Abstract

This contribution describes a geodatabase structure designed to manage a large amount of geo-environmental data for the "Gronda di Genova" highway by-pass tunnels in Liguria region (Italy). In particular, an innovative dataset structure founded on an explicit conceptual model was designed to represent the distribution of petrofacies containing Natural Occurring Asbestos (NOA), and their minero-chemical composition. This in order to assess the environmental risk (air dispersion of fibers) due to the tunnel excavation in the asbestos-bearing rocks. Problems related to the GIS (shp) - AutoCAD (layer) conversion have been also considered for delivering the graphic layout of the project and are here discussed.
