摘要：Automatic road map updating has been one of the difficult and important research topics in the community of geomatics. An operational road map updating system should include three key components: the generation of a new version of roads, the automatic road change detection/updating and the spatio-temporal modelling of road data. Special considerations have to be given to the spatio-temporal modelling of road networks, such as the decomposition of road attributes, the maintenance of road topological relationships, the choice of state-based or event-based modelling, etc. This paper presents a new spatio-temporal data model for road networks in which both the state and event information are integrated with road geometric and topological relationships. A prototype system for road map updating is developed based on the proposed data models. The system has demonstrated that it is necessary and possible to incorporate spatio-temporal modelling in a road network updating system
