Photogrammetric survey of the Hasas Baba Tomb and accuracy research in different software

Photogrammetric surveys have been used for years in the documentation of our cultural heritage. Photogrammetric studies are constantly being renewed thanks to the technology that has developed recently, and the branch of photogrammetry is frequently preferred in such studies. UAV (Unmanned Aerial Vehicle) photogrammetry has also gained a place as a highly preferred photogrammetry technique especially in recent years. In this study, Hasas Baba Tomb, which is located in Aksaray province center and whose exact date is unknown due to the lack of a written inscription, but which is thought to have been built in the late Anatolian Seljuk Empire or during the Karamanoğulları period considering its architectural features, was 3D modeled using UAV flight data and three different photogrammetric software. In this study where 3D modeling was performed with photogrammetric techniques, it was calculated that the position error was mxy=±3.39 cm and the height error was mz =± 3.04 cm in Agisoft Metashape Professional software, the position error was mxy=±3.66 cm and the height error was mz=±3.24 cm in Pix4D Mapper software, and the position error was mxy=±3.42 cm and the height error was mz=±3.28 cm in Context Capture software. According to these results, it was concluded that the position and height accuracies obtained from Agisoft Metashape Professional, Pix4D Mapper and Context Capture software are acceptable according to BÖHHBÜY.
