ABSTRACT

Ferrara, which grew up around a ford over the River Po, became an intellectual and artistic centre that attracted the greatest minds of the Italian Renaissance in the 15th and 16th centuries. The humanist concept of the 'ideal city' came to life here in the neighbourhoods built from 1492 onwards by Biagio Rossetti according to the new principles of perspective. The completion of this project marked the birth of modern town planning and influenced its subsequent development.
Ferrara was inscribed on the World Heritage List of UNESCO in 1995 "considering that the site is of outstanding universal value, being a Renaissance city, remarkably planned, which has retained its urban fabric virtually intact".
The multi-disciplinary research project developed by the Departmental Centre for the Development of Integrated Automatic Procedures for Restoration of Monument (DIAPReM, University of Ferrara) started in 2005 by the three-dimensional survey of the historical centre of Ferrara. The project was aimed at the experimentation of the 3D survey's technology for the urban scale, at the realisation of traditional drawings (plans, elevations, sections) and at the realisation of a 3D data-base of the urban context to the study, the maintenance, the enhancement and the management of the urban installations (plants, traffic signs, etc.). The data-base has been planned to be used as operative instrument for the Municipality to acquire and mange the architectonical heritage of the city of Ferrara toward an urban conservation trough the assessment of any action against the heritage preservation rules. The advantages of the research works applied to a three-dimensional model have been great: the 3D survey allowed working not on 2D representation, unable to an integrated spatial view, but on a reference model for any geometric check (curvature valuation, vertical or horizontal position of element in the space, abuse on the historic heritage by new architectural project) and for numeric analyses aimed at the structural assessments.
One of the goals of the research project has also been the increasing of the potential uses of the digital 3D models and the integration of the multiple cultural elements related to architectural projects.
During the research project the procedures for the integration of experimental methodologies have been pointed out to acquisition of dimensional, morphologic, colorimetric data and also to the study of the urban context, for the structural analysis and to the historical studies of the architectures.
This approach could be strongly linked to the current italian legal fame work on conservation action in order to preserve the historic urban landscape from any activity against its visual integrity.
