This article explores the feasibility of using interpolation and extrapolation methods to construct a digital elevation model in the forest-steppe zone. The feasibility of applying these methods in this geographic area is assessed, taking into account its features and the nature of the terrain. The challenges encountered in constructing digital elevation models obtained from photogrammetric processing of aerial photographs taken by an unmanned aerial vehicle (UAV) are described. A comparative analysis of the accuracy of various approaches is conducted. Factors influencing the accuracy of both methods are examined, including the percentage of forest cover and the location of forested areas within specific areas. The study identified the main factors influencing modeling quality, including the density of the initial data, the nature of the terrain, and the parameters of the algorithms used. The results obtained make it possible to identify the most effective methods for improving the accuracy of digital elevation models in the forest-steppe zone. The study contributes to the development of digital terrain modeling methods and can be used in the design of linear objects, planning environmental measures, agricultural work, as well as in topographic and geodetic work and mapping in the conditions of this natural zone.
