Periodic Reporting for period 2 - BiGAr (BIM and GIS Integration for Archaeology: a new method for documenting field archaeology)
Période du rapport: 2023-10-01 au 2024-09-30
Archaeologists are currently facing a challenge in documenting the three-dimensional nature of archaeological contexts and their evolution over time. Traditional methods have predominantly relied on 2D representations, limiting the comprehensive understanding of archaeological deposits. While recent advancements have enhanced 3D modelling, archaeologists still struggle to represent the Time dimension. Furthermore, the integration of these 3D models with other information collected (for instance, the databases) is still difficult.
However, the progress in the capacity of archaeologists in documenting the archaeological features is crucial for society to allow an effective preservation and valorisation of the Cultural Heritage as well as a correct understanding of the history of contemporary landscapes.
BiGAr project aims to improve archaeological research methodology by integrating Building Information Model (BIM) and Geographical Information System (GIS) technologies. The integration of BIM and GIS can be a groundbreaking solution that not only allows for the documentation of 4D archaeological evidence but also facilitates 3D models visualization and their analysis in the geographical space.
The overarching BiGAr’s objectives include:
- Developing an Open Source (OS) web-database (BiGAr web-database) to record and manage 4D objects, integrating the BIM approach into GIS.
- Writing the code for an OS application to integrate BIM and GIS environments.
- Testing the workflow and main outcomes in a case-study using data from excavation, field survey, and UAV survey, and transferring the technology to the EU.
The research fellow, Dr Marco Cavalazzi, achieved these objectives thanks to the collaboration of the involved organizations: the University of Bologna (Italy, Return Phase), the University of Michigan (USA, Outgoing Phase), and the University of Minho (Portugal, Secondment).
The work carried out during the project involves the research on BIM techniques and the creation of a web-database structure. The fieldwork at the Gabii archaeological site (Rome, Italy) and training at the University of Michigan (USA) and at the University of Minho (Portugal) contributed to achieving the research objectives.
Field work involved testing the BiGAr outputs processing new data collected during the archaeological excavations in three sites: Gabii (Rome, Italy), the castle of Zagonara (Lugo, RA, Italy), and Cervia (RA, Italy). Fieldwork was anticipated as originally planned, occurring simultaneously with WP1. This allowed better testing the BiGAr outputs and workflow with new data. However, because of that, there were delays in achieving Research Objectives 1 and 2, which were, respectively, to build the BiGAr web-database structure and to write the code of BiGAr’s GIS application for BIM-GIS integration.
Another group of tasks was finalised to training on web-database, BIM techniques, academic English, and additional courses, attended during the secondment period at the University of Minho. All training objectives were achieved.
Another group of activities addresses dissemination and outreach activities. The ER is effectively communicated the project progresses through a dedicated webpage, 7 international conferences, 4 papers (2 still under preparation), 2 workshops, one at the University of Michigan and one the University of Bologna, and several presentations - two of them specifically conceived for 6-8 years old children - in the USA, Italy, and Portugal.
The last group of tasks deals with project management, legal and contractual management, and reporting. All activities, deliverables, and milestones expected in this field were completed as planned.
Regarding deviations, the anticipation of fieldwork and testing phase affected the original schedule, leading to delays in research.
In terms of impact, the fellow strengthened technical skills, collaboration with ICT researchers, and collected new data during fieldwork, testing the outcomes of the BiGAr project. The plan for exploitation and dissemination of results has been adapted, but the networking efforts in the USA, Italy, and Portugal as well as presentations at international conferences further enriched the project. In conclusion, the BiGAr project has achieved notable advancements by addressing deviations, adapting its approach to enhance dissemination, outreach, and training efforts.
The project aimed the creation of an open-source application that integrates BIM and GIS environments. The ER established a BiGAr web-database structure and created an application to ensure the 3D data collection and visualization as well as the integration with databases.
This application facilitates the visualization of 3D models in the geographic space and the representation of the Time dimension. Its open-source nature ensures accessibility and continuous improvement by the academic community. Since year 1, the technology developed within BiGAr has been tested in concrete case studies, namely the archaeological excavations of Gabii (Rome, Italy), and two excavations of the Ravenna Landscape project, Zagonara (Lugo, RA, Italy), and Cervia (RA, Italy).
The activities performed have underscored the significance of digital approaches in archaeology, highlighting not only their potential impact in the academic sector but also their usefulness for local communities and society in general. While a more conscious and effective approach to dealing with digital archaeological data will provide new momentum to both field and theoretical archaeology, the kind of research conducted within BiGAr contributed to the development of new tools for recording and communicating research outcomes. This action will enhance the effectiveness and efficiency of archaeology in supporting society in preserving both Cultural Heritage and Historical Landscapes.
