This is the most updated version of the Reference Territorial Database containing the data structured according to an aggregated version aimed at shared data editing. The structure is divided into four layers: • A layer called "Topological Layer" to define the entire coverage of the soil which contains within it a single theme (land cover) and a single class "land cover" in which all the topological primitives that identify the land cover have been brought together.• A layer defined as "graph layer" which contains within it three themes (Viability, Hydrography, Services) each of which is responsible for the identification, through the appropriate classes, of the related networks.• A layer defined as a "non-topological layer" within which all the primitives are merged (points, lines and polygons) which contribute to defining the territory in greater detail without having topological constraints. The layer is organized into four Themes (Relevances, Orography, Administrative areas and Other) which contain the relative classes.• A layer called "Derived layer" which contains all the objects that can be obtained through automatic derivation from the detected objects present in the database. The layer is organized into three layers according to the different primitives - points, lines and polygons - which contain the relative classes. The data can be used via WMS/WFS services and vector data download as illustrated on the dedicated page of the Geoportal
