Abstract

This unit continues the examination of spatial interpolation by looking at areal interpolation techniques and some applications. Non-volume preserving and volume preserving methods are described, and two special cases of interpolation—mapping populated areas and estimating trade areas—are outlined. The unit concludes with notes on the conceptual foundation of interpolation and its appropriate uses in GIS.
