Abstract
A preliminary survey campaign is essential in projects of restoration, urban renewal, rebuilding or promotion of architectural and urban heritage. Today several survey techniques allow full 3D object restitution and modelling that provides a richer description than 2D representations. However, the amount of data to collect dramatically increases and a trade-off must be found between efficiency/productivity and accuracy /completeness of the results. Depending on the extent and the complexity of the task, a single technique or a combination of several ones might be employed. Especially when documentation at different scales and with different levels of detail are foreseen, the latter will likely be necessary. The paper describes two architectural surveys in Italy preliminary to a project of restoration and conservation: the old village of Navelli (AQ), affected by the earthquake in 2009, and the two most relevant remains in Codiponte (MS), damaged by the earthquake in 2013. In both sites, a 3D survey was necessary to effectively represent the objects. An integrated survey campaign was performed, which consisted of a GPS network as support for georeferencing, an aerial survey and a field survey made by laser scanner and close-range photogrammetry. Thanks to their peculiarities, the two case studies are exemplar to wonder if the integration of different surveying techniques is today still mandatory or, considering the technical advances of each technology, it is in fact just optional. The approach assigns to survey activities a central role, as a tool of critical knowledge through which the built heritage reveals the wealth of information of which it is the bearer. In particular, through a highly integrated approach applying both traditional tools and techniques and innovative methods, the archives permit the representation of the characteristics of the entire urban context in descriptive and interpretative graphic documents.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
