This paper primary summarizes the road-linear data models and its events. After analyzing the cadastral spatiotemporal database, it establishes the spatial events and attributes events based on the liner-spatiotemporal data actions. Also the spatial part and the attribute part are stored in the history and current tables according to the feature's time dimension. At the end, this paper organizes and designs the road-linear feature's model based on Oracle Spatial, and gives some query SQL sentences.
