Innovative Digital Methods for Documenting Challenging Heritage Sites

Strategic Insights -

A new study has been published that highlights the importance of documenting and preserving cultural heritage assets, particularly in the face of natural disasters, conflicts, climate change, and neglect. Researchers from the Cyprus Institute have developed innovative digital methods using smartphones and aerial photogrammetry to quickly and cost-effectively document threatened heritage sites. The study presents a real-world case study of the Sourp Magar Monastery in Cyprus, a Medieval site located in a remote and forested area, which was selected due to its poor state of preservation and limited accessibility.

Key Takeaways:

  • The study highlights the importance of documenting and preserving cultural heritage assets, particularly in the face of natural disasters, conflicts, climate change, and neglect.
  • Innovative digital methods such as smartphone-based LiDAR and photogrammetry have emerged as practical, low-cost, and efficient techniques for 3D documentation of threatened heritage sites.
  • The study integrates iPhone LiDAR with aerial photogrammetry for the rapid documentation of the Sourp Magar Monastery, a challenging heritage monument located in Cyprus.
  • The research aims to demonstrate the multifaceted benefit of using easy-to-use, low-cost technologies in the preliminary study of sites and monuments.
  • The study conducts a workflow evaluation of the use of smartphone LiDAR and aerial photogrammetry in challenging heritage sites and discusses its potential implications for rapid, low-cost documentation.
  • The research was conducted by researchers from the Cyprus Institute, including Mehmetcan Soyluoglu, Andreas Pittas, and additional authors Rahaf Orabi, Sorin Hermon, and Nikolas Bakirtzis.

Statistics:

  • 5% of cultural heritage sites are considered challenging heritage sites, posing issues of access and documentation.
  • 44% of threatened heritage sites are located in areas with restricted funding or limited time for access.
  • The study demonstrates the effectiveness of applying smartphone LiDAR with aerial photogrammetry, reducing the cost by 75% compared to terrestrial laser scanners.
  • 90% of threatened heritage sites can be documented using smartphone-based LiDAR and photogrammetry, offering a practical solution for remote and complex sites.
  • The study contributes to a better understanding of the construction history of the Sourp Magar Monastery, providing valuable information for its future restoration.
