Abstract :
The development of a spatiotemporal data model adapted to temporal GIS applications is still a challenging research issue. The paper presents a new definition of events and processes to describe and model spatiotemporal phenomena within GIS, based on which, and on an extended concept of object version, an event-based conceptual spatiotemporal data model is produced.
