A conceptual schema is essentially required to effectively and efficiently manage and manipulate dynamically and continuously changing data and information of moving features. In the paper, spatiotemporal schema (STS) is proposed to describe characteristics of moving features and to efficiently manage moving features data, including the necessity aspects: abstract data types, dynamic attributes, spatiotemporal topological relationships and a minimum set of spatiotemporal operations. On the basis of the proposal of schema, spatiotemporal object-based class library (STOCL) is further developed for the implementation of STS, which allows development of various spatiotemporal queries and simulations. The conceptual schema and implemented object library are then applied to the development of passengers' movement simulation and pattern analysis in railway stations in Tokyo.
