SYNOPTIC ABSTRACT
In this paper Geographic Information System (GIS) based spatial sampling procedures have been proposed for environmental studies in agriculture. In the proposed sampling procedures, an attempt is made to suggest a stratified sampling design in which not only the spatial nature of the environmental variables has been taken care by incorporating spatial correlation based on auxiliary character in selecting the sample but also the effect of clustering properties of environmentally polluted neighboring areal units is considered. It is proposed to stratify the study region based on neighborhood properties of the sampling units.
