STUDY OF MORPHOMETRIC RELIEF INDICATORS FOR THE PROBLEMS OF ENGINEERING PREPARATION OF TERRITORIES
The article provides a review analysis of existing methods for determining the degree of complexity of the relief, which refers to morphometric characteristics. The determination of the coefficient of complexity of the earth's surface relief is one of the important indicators in the practice of engineering design in making decisions on the acceptability of a project. It is proposed to determine the relief complexity factor based on a rectangular network of initial data (DEM). The finite difference method determines the quantitative value of the complexity of the surface of a local area based on a 3×3 matrix. By moving the local window of the 3×3 matrix along the rows and columns of global regular network of initial data, visualization of complex relief sections in the form of a cartogram is provided.
