ABSTRACT
The ability to derive spatially significant zones (e.g., water bodies, zones of influence) within a cluster of zones has interesting applications in understanding commonly sharing physical mechanisms. Using morphological dilation distance technique, we introduce geometrically based criteria that serve as indicator of the spatial significance of zones within a cluster of zones. This chapter focuses on the problem of identifying zones that are “strategic” in the sense that they are the most central or important based on their proximity to other zones. We have applied this technique to a task aiming at detecting spatially significant water body from a cluster of water bodies retrieved from IRS LISS-III multispectral satellite data.
