Bathymetric curves in digital format (vector) created through different procedures in relation to the type of original data: 1) by digitization from bathymetric maps available in paper format; 2) by manual interpolation of quoted points reported on paper; 3) for automatic interpolation of digital spot heights. The reference data are those of the seabed in front of the coasts of the Emilia-Romagna Region. It shows the bathymetric isolines derived by digitizing the information contained in the scanned tables, "PLANS - Control network project of the physical factors influencing the coastal balance - scale 1:10,000" related to the "PROJECT PLAN FOR THE DEFENSE OF THE EMILIAN-ROMAGNOLA ADRIATIC COAST, second phase, CONTROL SYSTEMS AND MEASUREMENTS OF THE FACTORS INFLUENCING THE DYNAMICS OF THE REGIONAL COAST, vol.V, control network of emerged and submerged morphologies - BATIMETRIE-Idroser S.p.A. 1985 ". Surveys carried out by the company Geosystem Parma s.r.l.
