Moving objects with multiple transportation modes (e.g., $Car$, $Bus$, $Walk$) can be represented by the reference method where the location is mapped to infrastructure objects, e.g., roads, buses, pavements. A scalable dataset is required to evaluate the performance of a database system managing these moving objects. To produce multimodal moving objects, infrastructure objects are essentially needed. Due to the major challenge of gaining real datasets, in this demonstration we propose a method create these infrastructure objects for different environments including pavement areas, bus network and indoor just from a given road network and some floor plans. An indoor viewer is also implemented in a database system for visualizing 3D indoor moving objects and trajectories. The work is to be used for evaluating the performance of a database system managing generic moving objects.
