Abstract. The use of digital images as a source data for analysis and knowledge of the built environment is a common and well-known topic, which has seen a significant increase in the last fifteen years thanks both to algorithmic and technological development. One of the sensor families which has shown significant development in the last period are those mounted on smartphones, which offer ever increasingly advanced solutions from the technological and technical point of view. Considering the portability, handling and continuous availability of these instruments, it is legitimate to wonder if their cameras can be considered nowadays an effective working tool for architects and restorers. So, is the metric data, that comes from smartphones images acquisition and processing, reliable and usable for the two main phases of analysis and representation of the built environment? Starting from the case study of a façade of a church in the historic centre of Rome, the article aims to determine the reliability of the data acquired from a smartphone for architectural analysis and deterioration mapping.
In the cultural heritage knowledge path, the survey process assumes a primary role as a tool to analyze and interpret through bibliographic and iconographic analysis and the study of reality. The case study analyzed in the article is the Castle of Canossa, the epicenter of some critical events in medieval times. The authors describe the first part of the research, mainly focused on the integrated survey process between active and passive techniques at architectural and territorial scales. Several geometrical validation steps have been introduced to verify the reliability of the 3D acquisition and historical reconstruction. The paper highlighted the crucial relationship between territorial heritage and buildings, laying the groundwork for a more articulated analysis of the entire architectural complex. The final aim is to realize a 3D BIM model that represent the current and the original architectures in the same type of environment.
Con l'obiettivo di favorire nuove modalità comunicative e di conoscenza per la valorizzazione dei beni culturali, il contributo propone l'analisi di un ambiente stradale come bene culturale unitario attraverso la lettura delle caratteristiche semantiche espresse dai singoli elementi architettonici e urbani. Come campo di applicazione si è scelta via del Parco Margherita a Napoli, nel quartiere Chiaia, che presenta forti connotazioni stilistiche dello stile liberty, sviluppatosi in Europa tra il 1880 e il 1910 e diffusosi a Napoli con caratteristiche linguistiche proprie, connotando in maniera permanente alcune zone della città di nuova espansione come quella in esame. A tale scopo, il contributo si propone di mettere a punto una metodologia di indagine per l'analisi e la documentazione critica di un tratto stradale che, a partire dalle quinte urbane, possa evidenziare la continuità di una consistenza stilistica che va oltre la facciata stessa, interessando spazi aperti e recinzioni tra spazio pubblico e privato. I dati acquisiti sia con il rilievo digitale che attraverso fonti documentali e iconografiche sono impiegati in applicazioni in ambiente GIS, per una proto-modellazione della strada che consenta di leggere in maniera unitaria i dati acquisiti. Si propone, quindi, attraverso la raccolta di dati e di informazioni eterogenee sui beni architettonici e urbani indagati, un racconto digitale di un percorso urbano stradale al fine di favorirne la conoscenza e la documentazione.
A fortified architecture may show multiple morphologies depending on the construction technique, the territorial context and role, the historical origin, and structure development. The dimension can range from the territorial scale, such as city walls or military outposts, to the individual building (tower, palace, gate) or portion of walls. Fortified castles are an admirable example of layered and complex structures with a substantial scale variability.They are composed of multiple interconnected defensive systems and architectural superstructures. Besides, fortified castles build a relationship and dependence with the surrounding influence area, defining its development. The territory becomes a filter of access, especially in the case of fortified castles positioned in dominant positions. Therefore, the analysis of these buildings cannot be limited to the architecture study. It is essential to interpret the internal and external ecosystem development.The case study reported in the paper is the Castle of Canossa (Fig. 1), a complex fortified building close to Reggio Emilia, Italy. The Castle's history
