RESUMO
The State Real Estate Cadastre of the Russian Federation and its technologic methods were substantially modified at every step of their development. This has caused the following: to date, the State Cadastral Registration contains the data for land plots, the boundaries of which have been set in accordance with the law, as well as the data for earlier recorded land plots without descriptions of boundaries and their demarcation afield. Additionally, the boundary description for registered land plots is often inconsistent with their real site location. One of the reasons is that the visual checking of site location for boundaries described by a cadastral engineer during the registration of land plots is not provided; so, it is impossible to identify the errors at once. The timeliness of this work is that a large volume of records for land plots accumulated in the Real Estate Cadastre requires adjustment and correction; and the performance of complex cadastral works which have been described in Russian legislation recently makes it possible to correct the errors and simultaneously specify the locations of all land plots within the boundaries of one or several closely-spaced cadastral units at once. The mission of the study is the development of methods for the implementation of complex cadastral works for position updating of land plot boundaries based on the data received using an unmanned aerial vehicle. To achieve this goal, the following tasks should be solved: • Articulate the concept and detect the background for the introduction of complex cadastral works in the Russian Federation. • Analyze the data of the State Real Estate Cadastre for land plots which are the targets for complex cadastral works. • Describe the technique of aerial photography using unmanned aerial vehicles and provide the assessment of the accuracy of positioning using orthophotoplans. The work reveals the procedure of complex cadastral works based on digital orthophotoplans; the technique of aerial photography using the compilation of unmanned aerial vehicles and orthophotoplans is described; the assessment of the accuracy of positioning by a digital orthophotoplan is provided. The performance of complex cadastral works will allow updating the data of the State Real Estate Cadastre and improving the efficiency of territory management. The procedure for complex cadastral works based on the data received using unmanned aerial vehicles has been developed.
