Atmospheric pollution particularly in urban area has a strong impact upon daily life. Lahore is the second largest city of Pakistan. Its economic growth and rising energy consumption are causing the increase in air pollution. The main sources of the air pollution are motor vehicles and industrial activities. SO2, NO2, CO2, CO, O3 and Particulate Matter (Pm) are investigated as the pollution indicators. This research is an endeavor towards the development of an Air Pollution Information System, which can support the dissemination of the information about different pollutants and can facilitate the identification of the most polluted geographical areas using Geographic Information System (GIS) tools and techniques.
