Survey for knowledge and communication of the architectural heritage: Case study Rocca di Codiponte

Abstract

A preliminary survey campaign is essential in projects of restoration or promotion of architectural heritage. 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 an architectural survey in Italy: the most relevant remains in Codiponte (MS), damaged by the earthquake in 2013, in the context of a project of restoration. In this site, a 3D survey was necessary to represent effectively the objects. An integrated survey campaign was performed, which consists of a GPS network as support for georeferencing, an aerial survey and a field survey made by laser scanner and close range photogrammetry. The case study, thanks to its peculiarity, can be taken as 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.
