The article deals with the practical aspects of improving methods of geodetic assessment of morphometric elements of the topographical basis of terrain with complex relief. It has been proven that an urgent task today is the development of a methodology for determining the elevations of a relief section by using informative and geoindicative characteristics, which ensures the accuracy and optimality of the parameters for drawing up topographic maps and plans. It has been established that the use of the geoinformation mapping method, in the conditions of areas with complex terrain, will provide users with the necessary information with a high degree of updating and accuracy.
This research proves that the use of modern devices of systems for fixing details of the earth's surface relief, the creation of the latest software products and technical solutions for digitizing data obtained during reconnaissance work make it possible to create information banks of unlimited volume, to form repositories for data arrays of measurements with multiple protection against loss of information of digital terrain models.
It has been established that the existing methods aimed at studying complex relief and determining the rational height of the relief cross-section necessitate the improvement or development of new methods for determining the optimal heights of the relief cross-section, thereby representing a certain scientific interest.
It is appropriate to use the method of choosing the optimal size of the relief cross-section based on the model representation of the patterns of changes in its values in a given range, depending on the degree of variability of the elementary heights of the relief irregularities using the statistical criterion of efficiency and composite probability distribution.
It is obvious that the empirical distributions of relief heights in areas of different complexity are described by different forms of the hypsographic distribution curve. At the same time, the empirical distribution of the relief heights of the flat area is described by the unimodal symmetrical relief height of the area.
