Abstract

The article provides a list of mathematical methods of aerospace monitoring, a method of assessing the demand for thematic tasks of aerospace monitoring, as an example of assessing the demand for mathematical methods in studying water bodies. Examples of the most effective methods for solving the task of researching the state of water resources are given. The use of the analysis method of hierarchies is proposed to assess the demand for methodological principles and tools for solving water use problems based on the methodology of aerospace geomonitoring. The method made it possible to assess the advantages and disadvantages of the considered methodical tools and to obtain a formalized generalized assessment of the level of relative demand for methodical tools for each of them. Based on the obtained results, it was determined that the most effective mathematical methods of aerospace geomonitoring are the method based on a statistical criterion, the method of the spatial-frequency spectrum and fractal analysis. The article provides an example of approbation of the methodological tools of the aerospace geomonitoring methodology for solving specific thematic tasks of water use, namely the result of using the method based on a statistical criterion to assess the state of the urban water environment in the city of Kyiv using the Opechen lake system and Verbne Lake quarry reservoir as an example. It's rare. The considered example of the analysis of the dominant directions of estuarine flows of the delta zones of the Dnipro and the Danube was obtained based on the spatial-frequency spectrum method. The result of the fractal analysis of the assessment of the variability of the components of the fluvial-littoral landscape of the estuarine regions of the rivers is presented using the example of the Kili estuary of the Danube.
