Abstract

Fuzziness widely exists in many spatio-temporal applications. The existing spatio-temporal data models lack the ability to describe and represent the internal mechanisms or semantic relation of fuzzy spatio-temporal objects. After investigating the semantics of fuzzy spatio-temporal data, this paper proposed a formal definition about fuzzy spatio-temporal data model. On this basis, it extended the UML data model to express fuzzy temporal and spatial data. Finally, an example demonstrates the potential usefulness of the proposed method.
