It?s the research hotspots that Spatio-Temporal Indexing Mechanism(STIM) in GIS, especially in vehicles monitoring and scheduling field. Then, it?s more important how to unite the time and space information, improve the query efficiency. At the beginning of design system, constructing Floating Model Indexing Mechanism(FMIM). It established a three-layers of data query structure, which can guarantee the effective Spatio-Temporal combination. According running track of vehicles, vehicle and operation is proposed based on t-Time Dual-mode Index Mechanism and T-Period Vehicle Monitoring Index Mechanism. The related technical has been commercialized, it can efficiently improve query efficiency. The regulatory platform running well.
