This is a study of visualization of positive data of by Positive Modified Quadratic Shepard (PMQS) method. This data visualization tool was implemented successfully in MATLAB using both recorded pollutants levels and geological coordinates of data acquisition points located in different localities of the metropolitan. These points were located in/around the potential air emissions sources like vehicular transport, industrial sector and residential sector dispersed all around the city Field measurements were carried for 12 hour (day time) at eight points each. An online VOC analyzer was used during field campaign to collect data of hazardous organic pollutants like benzene, toluene, ethyl benzene, xylene (BTEX). Constant concentration curves were generated in form of contour plots showing latitude, longitude and spatial distribution of recorded atmospheric pollutants.
