Assessment of structural degradation at Germus Church: A UAV-based study

Abstract

Turkiye, with its rich history, has witnessed the rise and fall of many civilizations over the
centuries. The preservation and documentation of historical artifacts and archaeological sites
left behind by these civilizations are vital for the transmission of cultural heritage to future
generations. In this regard, the application of photogrammetry has emerged as a promising
method for modeling cultural heritage, and it has gained significant popularity in recent years,
especially with the advancements in unmanned aerial vehicles (UAVs). In a recent study,
researchers conducted the UAV-based photogrammetric reconstruction of the Germus
Church, a historical structure believed to have been constructed in the 19th century. This
innovative approach combines the use of UAVs and photogrammetry techniques to create
accurate and detailed 3D models of the church. By capturing high-resolution aerial
photographs from different angles, the researchers were able to reconstruct the entire
structure digitally, capturing its intricate architectural details. The utilization of UAVs in
photogrammetry not only allows for efficient data collection but also offers a non-intrusive
method for surveying cultural heritage sites. This technology enables researchers and
conservationists to document and study historical structures with precision, aiding in their
preservation and restoration efforts. The study on the Germus Church serves as an example of
how modern techniques can contribute to the safeguarding and understanding of Turkey's
diverse cultural heritage. By employing UAV-based photogrammetry, researchers are able to
create virtual representations of historical sites, ensuring that the knowledge and beauty of
these structures are preserved for generations to come.
