No full textGeomatics is the neologism used today to group all the disciplines and techniques useful to give back 3D metric information about any kind of physical objects. The need to know the shape and the dimensions of an object is always devoted to specific applications, which use the geometric information to develop interpretation of specific phenomena. Archaeology has been one of the first historical disciplines more interested in the use of Geomatics tools due to the importance that not only the 3D description of the objects but also their localisation during the excavation activities have during the archaeological understanding and interpretation processes. Until the 70's of the last century, archaeologists used to manage by themselves measuring activities mainly based on the use of total stations; the continuous and rapid increasing of the Geomatics technologies forced to join the efforts by coupling archaeologists with surveyors in an interdisciplinary effort to reach the goals of the archaeological investigations. The IT developments influenced all the Geomatics techniques: land surveying has been enriched by satellite techniques, photogrammetry are now fully digital and in some cases also fully automatic, laser scanner based techniques and instruments has been developed both for land and built objects, GIS and BIM platforms are even more open solutions for geodatabases management. The common digital approach of all the Geomatics techniques allow a strict integration between the different technologies therefore a full and ever updated knowledge of the new possibilities of each technique is a mandatory requirement to obtain and manage metric data in a convenient way. Hung-e Azdhar archaeological investigations offer a complete view of the most advanced Geomatics applications managed by a multidisciplinary team formed by the Centro Scavi and the Politecnico di Torino expert

GIS e modellazione 3D: dalla conoscenza al restauro
No full textDocumentation is the process of gathering and organising the information necessary to define knowledge of a cultural property, to integrate the results of projects and restoration yards, so as to create a consistent database useful for the management of a cultural property in all its possible facets. Nowadays all disciplines involved in ‘knowledge' building must face the implications that the employment of digital data entails for the possible disciplinary research paths, in order to share and distribute the results of readings and interpretations homogeneously, and with easy accessibility for all specialists who base their analysis on them. All international Charters on restoration stress how historical and metric knowledge constitute the essential bases for any documentation of a cultural property capable of supporting any other specific analysis required to face the complexity of a restoration project, and later the planning of policies for post-intervention enhancement and management. In such context the technology of GIS (Geographic Information Systems) and of BIM (Building Information Modelling) represent a viable answer to supply a consistent and sharable platform for all analysis data (historical, metric, of material and structural deterioration, etc.) which, because of their common geographic reference matrix, allow to provide final results generated by the crosscheck information-power of every single data item. Starting from the results of some experiences carried out by historians and surveyors in the city of Turin on projects by Alessandro Antonelli, the contribution highlights the potentialities of the integrated approach as the possible structure of a shared database for successive restoration interventions and enhancement of an urban contex
UAV (Unmanned Aerial Veicles). Possibili utilizzi per il monitoraggio dei beni architettonici e paesaggistici
No full textFor over ten years UAV (Unmanned Aerial Vehicles) have been the object of research of many scientific disciplines, in an effort to test their potentialities in different sectors, in connection to the metric and physical survey of objects of difficult accessibility. The approval of regulations for the professional use of such devices has, since last year, enabled to effectively define the actual possibilities of employment in the field of territorial survey and monitoring. The limited distances of acquisition that such devices allow for open up a range of possible applications, also within the broad scope of the monitoring of Cultural Heritage with specific reference to single buildings, urban centres, landscape heritage and archaeological sites. Monitoring is an essential action for the proper conservation policy of Cultural Heritage and a preliminary action for any intervention project on i
