In order to estimate different parameters such as heavy metals that existing in soil, changing point information to area are binge used. In this case, different method are existed.In this study, we used the Ordinary Kriging method for estimating amount of cadmium in soil the Esfahan province. Then map for estimating spatial distribution of the total cadmium with use of GIS ability, it was classified for recognition of the polluted regions with the cadmium. Variance analysis test shown that land use is significant effect on total cadmium existed in soil. As, in urban and industry uses, mean of these heavy metals were much than their mean in the other uses. This explains that human activities are the most important factor for increase amount of heavy metals exists in soil. Examination results of total cadmium description statistics and compare those with suggested value by the other countries shown that soil of this region is contains pollution for purpose of cadmium quantity. With use of ETM+ sensor and spectral unmixing techniques, vegetation covering of region was extracted and up to date. Amount of pollution expansion distinguished in different regions of vegetation covering with fitness to map of pollution soil and vegetation covering.
