The origin of the unusual landforms of Baer?s mounds on the Near-Caspian lowland is not well understood. One of the possible approaches to the understanding of natural history of the region is searching of similar regions. In the many papers the problem of mounds origin is revised but with not of review of geomorphological analogues in the World. Some author states that are not exist of similar landforms anywhere else. The topography characterize by the sets of parallel ridges and hollows / valleys. Range of lengt...

The algorithm for computation of the spectral characteristics of terrain was prepared. The periodicity of Earth surface is specific В«fingerprintВ» of the cooperation of geological structure, exogenic processes and history of nature development for geomorphologically detached areas. For computing we used DEMs and 2D discrete Fourier transform with moving quadratic window of different sizes. Matrix of elevations decomposes in the Fourier image which defines harmonic waves set. All set of waves determine height fiel...

Quality of trend-surface approximation of four sites on East European plain was estimated. The sites were selected under condition of location in the landform's regions with different genesis of Earth's surface according to Geomorphological map of USSR 1:2500000. This regions includes are initial plain (Caspian lowland), areas of moraine (Smolensk-Moscow upland) and erosional (Central Russian upland) relief, structural and erosional UralпїЅs foothills. Two types of approximation methods were used: 2D algebraic pol...
