PHOTOGRAMMETRIC MODELLING OF HASBEY DAR'ÜLHUFFAZ (MASJID) USING AN UNMANNED AERIAL VEHICLE

Cultural assets constitute the bridge between our past and future in the geography we live. Protecting the artifacts that survived until today and bear the experiences of history and, more importantly, passing these down to future generations are of great importance for our country. Protecting and sustaining cultural assets are duties of mankind for the sake of ownership of universal values. Therefore, documenting all cultural assets in the geography we live in is a necessity. To this end, documentation practices for cultural assets bear great significance in terms of both historical development and contributing to the world cultural heritage. This article discusses the 3D photogrammetric modelling of Hasbey Dar'ulhuffaz (madrasa for training hafiz) from the Karamanids era, which is located in Ayine Street, Mucellit Neighborhood, Meram District in Konya Province. Within this scope, firstly, four control points that cover the aforementioned cultural asset were established in the study. The coordinates for these points were determined with a Topcon FC-250 GPS. Then, photographs of the cultural asset were captured with Nikon D90 camera and aerial photographs were taken with DJI Phantom 4 unmanned aerial vehicle. DJI Go 4 and Pix4Dcapture mobile applications were used to capture photographs using the unmanned aerial vehicle. All data obtained were evaluated via Agisoft PhotoScan and Netcad software, and a 3D model of the artifact was acquired. Documentation of the 3D models for artifacts in question contribute greatly to the world cultural heritage. At the same time, the 3D model obtained constitutes a substantial and accurate resource to pass down the artifacts to future generations. The most important point is to provide an opportunity for a faithful restoration in case of any potential damage to this historical artifact from physical intervention and natural disasters. It is foreseen that this model will also offer solutions to the problems of many professional disciplines today.
