Abstract
Various studies have been carried out on the documentation of cultural heritage with different methods. The correct data collection method is as important as the selection of the method to be used in the studies. Documentation studies focus on saving time and cost rather than data collection methods. However, obtaining accurate and complete data increases the accuracy of the documentation work. At this point, image-based documentation studies such as photogrammetry provide important contributions to operators. Although a single data collection tool is preferred in most of the studies conducted with the photogrammetry method, it is necessary to obtain images from different locations (ground and air) for accurate and complete data. Recently, the term Unmanned Aerial Vehicles (UAV) photogrammetry has emerged with the use of UAV in documentation studies. In this way, a complete model is created in the documentation studies to be performed by collecting data from both the ground and the air. In this study, three different data collection methods were used for documentation. Hybrid data collection approach, Terrestrial Laser Scanning (TLS) and Close-range Photogrammetry (CrP), and UAV photogrammetry techniques are selected and presented. Finally, three-dimensional (3D) data of Soli-Pompeiopolis were created by combining these point clouds.
