Abstract
With the development of temporal GIS (TGIS),
users are not satisfied with the traditional static 2-
dimensioinal maps any more, for the real-world entities
are evolving in both space and time. Many papers
have been brought to propose data models and
query languages for TGIS applications. However they
are not really adapted for the representation of dynamic
geographical phenomena. The current concept
of version is not suitable for storing continuous entity
evolving information. To fulfil this work, this paper
discusses the extended concept of version, called
dynamic version, for modelling spatiotemporal entity
evolution. The new definition of events and processes
this paper presented allows for comprehensive decomposition
and representation of complex spatiotemporal
phenomena. Two application examples of our approach
are brought out to discuss how we express
temporal relationships among geographical entities
and links describing their joint evolution. |
