Summary	Spatial analyses are important in environmental health research. This paper discusses three different methods to help manage data for complicated analyses, interpolation, kernel density estimation and snapshotting. The three methods were compared and contrasted and appropriate applications within the context of estimation of environmental exposure were proposed.
