Abstruct-The variogram function used in geostatistical analysis is a useful statistic in the analysis of remotely sensed images. In Part I1 of this paper, using the results derived in Part I, the basic second-order, or covariance, properties of scenes modeled by simple disks of varying size and spacing after imaging into disk-shaped pixels are analyzed to explore the relationship between image variograms and discrete object scene structure. The models provide insight into the nature of real
