Testing a protocol for optimizing the positioning of cameras for photogrammetric surveys: tools and methods

The MAP-Aria laboratory has long been a pioneer in using digital technologies for surveying, documenting, and preserving architectural heritage. Its multidisciplinary approach—combining architecture, engineering, computer science, and history – has led to the creation of advanced tools and protocols adapted to heritage-specific contexts. The lab specializes in spatial and temporal data acquisition through laser scanning, photogrammetry, multispectral imaging, and drones, while developing alternative solutions to overcome technical or regulatory challenges. Since drone and scanner use is often restricted by safety, accessibility, or legal constraints, MAP-Aria has engineered innovative substitutes such as cranes and cable-cams to maintain precision and data quality. These tools not only ensure rigorous documentation but also enable deeper analytical and cognitive understanding of heritage. Recent experiments in Santa Maria Capua Vetere, where ancient remains lie beneath the modern city, have demonstrated the laboratory’s ability to adapt its methods to complex environments, confirming its role as a leader in digital heritage research and conservation.
