Abstract

AIR POLLUTION in metropolitan is one of the most important issues to all of the city and environmental planners. Statistical methods, REMOTE SENSING and GIS technologies have been used to map and monitor urban air quality during the past. Here based on the statistical, image processing and spatial analyses of different data, the distribution of air quality parameters were mapped for Tehran metropolitan city. In this regard, hourly based observations (6 stations) for air quality parameters (i.e. CO, NOx, SO2, NO2) STATISTICS based on k-means clustering were analyzed. CO concentration map was generated using Kriging interpolation technique in Arc/GIS environment. Within Landsat ETM images acquired on 18-07-2000, 03-07-200 I and 09-08-2002 areas that have environmental, morphological and pollution similarities with real observation stations were extracted. Based on correlation coefficients between CO concentrations and ETM band 6 in each real station. CO concentrations in all similar areas were calculated. CO concentration map was produced using Kriging interpolation technique for entire city. The results of statistical study show that the pollutant concentration is going to be high at high traffic times. And in the spatial point of view, it is within the CBD. Very less difference was resulted from comparison between real CO concentration and estimated CO concentration calculated from image data. Map produced based on the above procedure showed a better spatial distribution of CO concentration with respect to environmental and morphological condition.
