The Effect of UAV Usage on Detail Points in Cadastre Update Studies: Çorum-Karaköy Case Study

Abstract

In Turkey, cadastral studies to determine the position, areas, and legal status of the real estate parcels have been carried out for a period of approximately 100 years by various laws, measurement methods, measurement instruments, and substrates. In Turkey, it is necessary to update 40% of the existing parcels because of problems such as produced cadastral substrates that do not reflect the ground structure, inadequate standards for technical reasons, and insufficient spatial data for the establishment of systems. The technical part of the studies for the cadastral update is carried out by the use of modern measurement methods and advanced technological devices, with the contribution of the private sector by the tender procedure. The unmanned aerial vehicle (UAV), which is one of the technological devices, can provide three-dimensional appearance and accuracy, the ability to interpret the land, and time reduction in the studies for cadastral updates. In this study, the contribution of data obtained by a UAV to the detailed studies was investigated for 56 parcels on a cadastral island that has an area of 24.71 ha for the renewal of cadastral parcels related to Karaköy Village of Çorum Province, Osmancık District. The number of detail points determined by the classical method was 392, while the number of detail points determined by the UAV was 682.
