Modelling of a temporal object-oriented geographic information system

David Edward Disalvio, University of Nevada, Las Vegas


Much research has been performed in recent years in object-oriented technologies. First, object-oriented programming languages were developed and more recently object-oriented databases. Geographic information systems have also been the subject of research during this time. While many models have been developed that add the concept of time to an object-oriented database, most of this work has been concentrated on efficient temporal queries. We feel that another important use of temporal databases is the ability to sequence through historical data efficiently. We will add this temporal feature to an object-oriented geographical information system.
