Modeling moving objects has become a topic of increasing interest in the area of video databases. Two k ey aspects of such modeling are object spatial and temporal relationships. In this paper we i n troduce an innovative w ay to represent the trajectory of single moving object and the relative spatio-temporal relations between multiple moving objects. The representation supports a rich set of spatial topological and directional relations. It also supports both quantitative and qualitative user

These algorithms can handle both exact and similarity m a t c hes. We also discuss the integration of our moving object model, based on a video model, in an object-oriented system. Some query examples are provided to further validate the expressiveness of our model.
