The Possibility and Effectiveness of Using Drones When Performing Cadastral Works


The analysis of the capabilities and effectiveness of the aerial survey using a drone for determining the coordinate points of the real estate objects’ boundaries with photogrammetric method in doing cadastral works basing on established requirements is given. The matters of coordinates’ definition accuracy are considered basing on the results of research trials of hardware and software systems of digital aerial photography and photogrammetric processing based on using drones and the aerial photos of the polygon. The results of a comparative analysis of the aerial survey effectiveness using drones of various types and traditional aerial survey with manned aircraft are given. The factors affecting the efficiency are analyzed. Issues of creating the legislation base for aerial survey with drones are discussed. The conclusion is made about possibility of aerial survey using unmanned aircraft to determine the coordinates of the real estate objects’ boundaries with precision meeting the established requirements. Planning aerial surveys with drones for cadastral tasks should be primarily based on economic factors (time and cost), taking into account the specific conditions of the subject and used hardware and software.
