Applying Kriging Approach on Pollution Data Using GIS Software

Environment pollution is a major problem in developing countries these days. Air pollution in particularis a cause of many diseases.In the present study an attempt has been made to map the pollution areas of Agra and predict the pollution at unsampled location.For this thirty places of Agra are selected for collectingair samples.Geographic Information System (GIS) and Kriging (Ordinary Kriging) approach is used to show the polluted and unpolluted areas in Agra (Dayalbagh) region. GIS tool have become an important component of pollution detection methodology. Ordinary Kriging used here is an interpolation technique. The semivariogram is plotted to show the relation between lag distance and semivariance. The Ordinary Kriging filled the map with different colors. Each color corresponds to different value of air pollution. Spatial Analysis and Decision Assistance (SADA) GIS software is used in the present work for the prediction of the pollution level at the location where sample is not taken.
