The topic of uncertainty management is a new issue in spatiotemporal database research. Some efforts have already been made on the indeterminacy representation models

while the area of topological relations models for indeterminate spatiotemporal objects remain untouched. The goals of these models are to provide a set of Joint Exclusive and Pair wise Disjoint topological relations for uncertain spatiotemporal objects. This paper presents a topological relations model for indeterminate evolving 2D regions. It checks the correspondence between 3d topological relations and spatiotemporal relations

provides restrictions to make the 3d relation model fitful for spatiotemporal objects. Then it extends Egg/Yolk model to the third dimension that can describe the approximate topological relations for indeterminate evolving regions. The result is a collection of relations clusters which have different spatiotemporal nature.
