Analyzing Air Quality Using GIS Tools

In this article the main topic of interest is to explore the analyzing possibilities offered by the latest version of ArcGIS Pro. At the same time, we want to highlight the use the 2D and 3D products obtained, but also the means of their subsequent analysis in the established GIS environment. We chose to use several methods of data investigation. The purpose of this work consisted in determining the air quality based on the measured values of the PM 2.5, PM 10 and NO2 indicators, over three days, with the help of sensors mounted in Bucharest and in its proximity. For the visualization and analysis of spacetime data, a space-time cube (STC) has been created. The trends in the Emerging Hot Spot Analysis were identified and visualized in three local scenes for a 3D visualization, based on this. The results and conclusions were extracted based on time charts, density analysis and graphs.
