Efficiency of use of unmanned aerial vehicles for the preparatory stage of evaluation works

Abstract

The Purpose. The purpose of the study is to prove the effectiveness of the use of unmanned aerial vehicles for the preparatory stage of evaluation works. In the process of development of modern methods of remote sensing of the territory of populated areas, the problem of using unmanned aerial vehicles for real estate evaluation is gaining relevance. Aerial surveying has been an effective tool for geodetic work, geophysical research and various types of monitoring for several decades. Modern technologies for creating topographic and cadastral plans are based precisely on the use of digital aerial photography materials [Burshtynska H., Stankevich S., 2013]. However, the cost of using airplanes and helicopters for local large-scale shooting is an order of magnitude higher and therefore. an alternative solution is to use UAVs for property valuation. The Methodology. The methodology is based on the need to use UAVs to assess the market value of real estate. The creation of large-scale plans of rural settlements based on data obtained with the help of UAVs is necessary for the design of master plans [Glotov V., Korduba Yu., 2011; Glotov V., Gunina A., 2014]. And this, in turn, is connected with land accounting and setting boundaries in a certain region, as well as the need to assess the market value of real estate. Unmanned aerial vehicles are widely used for aerial photography, as they are an inexpensive alternative to traditional filming from airplanes, helicopters, hang gliders, and satellites. In addition to high economic efficiency, i.e. a tenfold decrease in price, UAVs have additional advantages compared to traditional aerial and space shooting. The Results. The conducted studies prove the importance of using UAVs in real estate evaluation. The purpose of using a UAV is to obtain images of the territory with given characteristics. It is known that aerial photography, as a type of remote sensing of the earth, is an economically and technologically justified way of collecting spatial information, the basis for creating cadastral plans and maps, three-dimensional models of the terrain and terrain [Glotov V., Tserklevych A., etc., 2014]. It is proven that the efficiency of the proposed method exceeds by 36% the traditional methods of real estate evaluation. Scientific Innovation and Practical Significance. For the first time, research was carried out related to the possibility of using UAVs to estimate the market value of real estate. The article proves that the use of unmanned aerial vehicles at the stage of collection and analysis of initial data will make it possible to reduce the cost of determining the geometric characteristics of the object of evaluation by ten times compared to traditional geodetic methods, as well as speed up the process of selecting similar objects for the purpose of building mathematical models determining the market value of the relevant real estate segment. It has been proven that unmanned aerial vehicles have significant advantages compared to traditional methods of filming, namely: the possibility of obtaining ultra-high resolution (units and tenths of a centimeter) on the terrain; the possibility of detailed filming of small objects and small areas where it is completely unprofitable or technically impossible to do it in other ways, for example, in the conditions of urban development; mobility; high efficiency; environmental cleanliness of flights; high economic efficiency (decreasing the cost of work tenfold), etc.
