Purpose. The study of the effect of errors in the position of landmarks obtained using unmanned aerial vehicles, on the value of real estate. Aerospace for several decades is an effective tool for conducting geodetic works, geophysical studies and conducting various types of monitoring, but such methods are not used to assess the real estate. Modern technologies for the creation of topographical and cadastral plans are based precisely on the use of digital aerosol materials. However, the cost of using airplanes and helicopters for local large-scale take-off is on an order of magnitude higher and therefore an alternative solution is the use of UAVs. Methodology. Unmanned aerial vehicles (UAVs) are most often used as a cheap alternative to conventional airplanes from airplanes, helicopters, telescopes and satellite (satellite) takeoffs. In addition to significant cost-effectiveness (cheaper by ten times), UAVs have additional privileges, namely: low altitude, point-and-shoot, mobility, environmental cleanliness of flights. Land management works are mostly carried out unsystematically and without reliable control, and therefore the application of usual geodetic methods and measurement results does not allow obtaining the required precision of the coordinates of the points, boundaries and the film basis. All this leads to the problems of combining the boundaries of adjoining areas due to the use of poor-quality cadastral information in databases that were formed over a significant period of time by the regional centers of the SLC. Results. The use of UAVs proves the importance of them to perform valuation works, which will increase the accuracy of the determination of the coordinates of the boundaries of real estate and significantly accelerate the evaluation procedure. It is established that for large settlements, the accuracy of the determination of the coordinates should be significantly increased, since the cost of real estate in these settlements is quite large and, accordingly, the errors in determining the coordinates of real estate objects lead to errors in the cost of real estate objects of the settlement, which is legally unacceptable and therefore For very large cities it is expedient to create shots at low altitudes and gradually increase the accuracy of photographing the terrain. Scientific novelty and practical significance. The importance of using UAVs for assessing the value of real estate objects has been proved, as the resulting calculations result in average square errors in the value of 1 sq. M of real estate, amounting to less than 0.3% of its total value. The practical significance of the use of UAVs lies in the existence of additional advantages over traditional shooting methods, namely the possibility of obtaining a super-distinction (one and ten centimeters) in the terrain; the detailed removal of small objects and small areas where it is completely unprofitable or technically impossible to do in other ways, for example, in urban development.
