Web mapping of air pollution in Lviv

Abstract

SUMMARY The condition and composition of atmospheric air are influenced by two main factors: the entry of pollutants into the atmosphere through various sources and harmful physical effects on it. The latter include radiation, sound vibrations, noise, and so on. These and other factors disrupt the optimal condition of the air, which adversely affects human health, condition and development of animals and plants. The main sources of pollutants in the air of Lviv are: dust - vehicles, woodworking and building materials industry; sulfur dioxide - industrial enterprises, carbon monoxide - vehicles, thermal power plants; nitrogen dioxide - heat and power companies; formaldehyde - motor transport, woodworking industry. Today, emissions from mobile sources are the biggest air pollutants in the city. The chemical composition of emissions from mobile sources is characterized by the predominance of carbon monoxide (up to 74%), nitrogen compounds and hydrocarbons (12% and 11%, respectively). Today the state of atmospheric air in large cities of Ukraine and, in particular, in the city of Lviv is at an unsatisfactory level. The main problems in this area are the progressive nature of the negative impact on the ecological state of the environment and human health. As there is currently no interactive cartographic material that would visualize the problem of environmental pollution, the main purpose of this work was to create an interactive web map of the quality of life of the population of Lviv in terms of air pollution. To achieve this goal, we collected and systematized geospatial statistical cartographic materials on the ecological state of the air in Lviv. The necessary software for the development of an interactive map of air pollution has been identified and its possibilities have been studied. An algorithm for uploading geospatial data to the created web resource has been developed. The template of applications for the creation of web maps of air pollution in Lviv was chosen in accordance with the indicators of 2020, which were measured at 30 intersections of the city. Thus, two interactive web maps of air pollution in Lviv were developed in the environment of “Google My Maps” and “ArcGIS Online”.
