Modeling and management of spatio-temporal objects within temporal GIS application framework

In this paper, modeling and management of spatiotemporal-thematic data within an object-oriented GIS application framework, are presented. The object-oriented modeling concepts have been applied in integration of spatial, thematic and temporal geographic information in the conceptual spatio-temporal object model presented using standard UML class diagram notation. By its implementation in object-oriented application domain and (object-) relational database domain, spatio-temporal object database kernel has been developed as a spatio-temporal object storage manager. Based on spatio-temporal object database kernel and development of appropriate components on top of it for temporal GIS application functionality, a temporal GIS application framework has been developed. Description of its architecture and functional components dedicated to management of temporal aspect of geographic information is given. Desktop- and internet-based temporal GIS frameworks are further refined from generic framework.
