Application of Geoinformation Systems in Urban Environmental Management Projects

The environmental safety of the country is an integral part of national security, which is vital for determining the quality and comfort of conditions for all types of human activity. The paper proposes an assessment of the level of air pollution using geographic information systems in projects of urban environmental management. The problem of assessing the level of environmental safety, namely man-made air pollution by traffic flows, is complex and multifactorial and involves solving a number of scientific and practical problems. These problems are related primarily to defining the source of pollution, as well as to developing a method for quantifying the level of ingredient pollution and visualizing the processes of spatial and temporal distribution of air pollution. Geographic information systems are one of the tools that allow to effectively model the level of air pollution and display its spatial and temporal dynamics. Using geographic information systems, we modeled and visualized the level of air pollution within the metropolis. The results of the study are useful to monitoring the air quality in real time, thus allowing to prevent critical situations in which the concentration of pollutants exceeds the maximum permissible values, identify emission reduction strategies and implement preventive measures.
