The text proposes a reflection on drawing and architectural survey as a tool for the study of archaeological sites. The description of the Masada site and the events that have characterized its most recent history till to the definition of the documentary strategies have established a system for the development of a path of knowledge developed in synergy between didactic and research.
The city of Pavia, longbard capital, is characterized between its historical and artistic values also in the identity of fortified city. The presence of a military wall system originates from the Roman foundation, evolving through the Middle Ages and the Spanish domination with the development of three different circles around the historic center, background of central political events in Italian history in Europe. Through its morphological, stylistic and monumental features, the city wall and gates have influenced urban development and civil and religious heritage, developing a deep system of interaction between city, population and history that has left a marked sign both in the architectural form and in local cultural traditional systems. The implementation of Post-War Regulatory Plans has led to expansion policies careless of the fortified historical identity of the city, sacrificing military memory in terms of expansion and infrastructural actions and leaving to destruction the remaining ruins. In the context of enhancement of Pavia "historical city" identity, the cultural promotion goes through proposals for digital investigation and 3D Structure from Motion documentation of ancient urban walls, with morphological and architectural systems of analysis integrated to historical research, identifying protocols of Virtualization towards possible restoration, urban recovery and cultural enhancement actions.
The 43rd UID conference, held in Genova, takes up the theme of 'Dialogues' as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with 'others', which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, "dialogue" as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title 'translated' into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences.
[EN] Cartagena de Indias, one of the main Spanish commercial ports in the Caribbean Sea, was strategically built on a system of islands and peninsulas that formed a lacustrine system along the coast of Tierra Firme, known today as Colombia. For several centuries, Cartagena fortifications have been at the fore-front of Spanish military technologies. This site became the scene of action of the main military engineers at the service of the Spanish crown. In 1586 Battista Antonelli received from King Philipe II the task to design this monumental defensive system. The first project for the Cartagena wall enclosure (1595) is due to Battista and it was continued and modified by his nephew Cristoforo Roda. Nowadays, Antonelli walls still fit into the urban fabric of the city and delineate the perimeter of the historic city. The research project follows the previous research experiments conducted by the Lab DAda-LAB of the University of Pavia in the territory of Panama for the study of the Antonelli fortifications systems of Portobello and San Lorenzo del Chagres. It concerned an extensive action aimed at the documentation and to the study of the entire fortified system of the historic center of Cartagena. The perimeter walls of the old city and the fort of San Felipe de Barajas have been documented through the use of a mobile laser scanner that uses SLAM technology, evaluating the most effective performed strategies for fast survey activities. In parallel, a more specific action was conducted on the portion of the Baluarte of Santa Catalina walls, where it was possible to give a comparison between different methods and instruments, in order to verify the reliability of the 3D databases. Analysis protocols have been developed for the documentation and study of the defensive system. The paper will highlight the construction technologies that qualify the fortresses of Cartagena de Indias and the results obtained by the comparison between different data acquisition technologies to evaluate the quality of the models for the ...
