Abstract

Representation and reasoning about dynamic spatial phenomena requires at its foundation a formalism of spatial change. This article extends the understanding of topological change by providing a classification and analysis of events associated with changes in topological structures of spatial areal objects as they evolve through time. Tree structures are employed to represent topological relationships between regions and holes of areal objects. Basic and complex changes are specified using structure-preserving mappings between trees. Furthermore, the article constructs a normal form and proves that it is the simplest form that can represent all the changes under consideration. [ABSTRACT FROM AUTHOR]
