The Gamher Research Project for Metric Documentation of Cultural Heritage: Current Developments

Abstract

<p><strong>Abstract.</strong> GAMHer (Geomatics data Acquisition and Management for landscape and built Heritage in a European perspective) is a three-year research project financed under the Italian PRIN 2015 framework (Progetti di Ricerca di Rilevante Interesse Nazionale). The project, started in February 2017 under the University of Bologna coordination, links other 5 Italian research groups mainly involved in Cultural Heritage (CH) documentation and data management: Politecnico di Milano, Politecnico di Torino, IUAV Venice, University of Florence, University of Cassino and Southern Lazio and University of Bergamo.</p><p>GAMHer aims at exploiting some research and practical challenges in those disciplines devoted to generate 3D models for objects related to both landscape and built heritage; primary focus is then on digital photogrammetry and 3D scanning. These techniques are more and more applied in different contexts, having as the main subjects monuments, buildings, natural and urban landscapes. Some critical points however remain for their implementation, also facing to the new European directives, strictly connected to the requirement of the Digital Agenda for Europe. A wider use of digital data has to be achieved, in Europe as well as internationally, and therefore an analysis of the current developments is significant, together with a critical assessment of their performances.</p>

Improving Quality and Inclusive Education on Photogrammetry: New Teaching Approaches and Multimedia Supporting Materials

“…The final metric accuracy is strictly related to the purpose and field-of-use of the real-world digitization, which can be extremely varied and tailored for different needs: from documentation, monitoring, conservation of built heritage, artifacts, landscape, environment to the production of contents for videogames, tourism, art, additive manufacturing, communication and so on. The appropriation of this technique from many people, thus not being a prerogative of only specialists anymore, entails some risks: the ease of use makes possible the production of 3D models without any critical awareness of the metric quality (Bitelli et al 2019). One way to maintain a sort of control over this trend is education: correct information about photogrammetry, how to use it, and what can be produced.…”

From 3D surveying to replica, a resource for the valorisation of museum artifacts. The case of the bas-relief of Giovanni da Legnano in Bologna.

“…In recent decades, the use of 3D modelling techniques increasingly versatile and widespread has offer the possibility to explore new opportunities not only in the documentation and study of Cultural Heritage, but also for the communication and museum use of objects and artworks [1,2].…”

The Complex of Santa Croce in Ravenna as a Case Study: Integration of 3d Techniques for Surveying and Monitoring of a Historical Site

“…Geomatics nowadays can offer many techniques devoted to the digitalization, the documentation and the management of objects related to archaeology and built heritage (e.g. Ioannides & Quak, 2014;Tucci, Bonora, Conti, & Fiorini, 2017;Balletti, Bertellini, Gottardi, & Guerra, 2019;Bitelli et al, 2019;Girelli, Tini, Dellapasqua, & Bitelli, 2019) and the management of these data inside interdisciplinary researches is of increasing interest.…”
