Determination of Material Volume Using UAVs in Land Surface Change: The Case of Konuralp Campus (Düzce)

In this study examined the availability of UAV in determining material volume in excavation and fill works. The study aims on calculating the volume of an excavation work areas 1841 m² at the parking lot of the Faculty of Sports Sciences at Düzce University Konuralp Campus and a filling work areas 2759 m² on the access road to the Environmental and Health Specialization Laboratory. Autonomous UAV flights were performed before and after the excavation and filling works in the study areas. Besides, following these UAV flights, terrestrial measurements were made in the same way. The study was founded that UAV data analysis results an excavation volume of 7121 m³ in the parking area and a filling volume of 5752 m³ on the road. According to calculations used terrestrial measurement methods, the excavation volume in the parking area was 7007 m³ and the filling volume on the road was 5683 m³. An average difference of 1.42% was found between UAV data and terrestrial measurement methods. The results were showed the usability of UAV systems in detected material volume.
