Sites included in the UNESCO World Heritage List "The Wine Landscapes of Piedmont: Langhe-Roero and Monferrato" (linear zones)

The linear figure represents the buffer zones (buffer zones) of the wine-growing landscapes of Piedmont and derives from the shape files developed by the Istituto Superiore sui Sistemi Territoriali per l’Innovation (SiTI), of which it specifies to a more detailed scale the perimeter.The identification of buffer zones, resulting from the merging of 30 Landscape Units of the Regional Landscape Plan, was drawn, depending on the sections, on the municipal borders (Istat 2011). on the BDTRE (particularly on roads, railways, watercourses), orthoimages and cadastral particles.The scale of acquisition therefore varies according to the source used, from a definition of more detail in the case of cadastral parcels (1:2,000), up to a maximum of 1:10,000 for BDTRE or orthoimages.
