Aiming at the disadvantages in spatial data management of traditional spatial data record system on the global scale,such as the lack of large-scale or global standard management for data mapping range and spanning mapping junction,a set of space-time record system,which is based on spatial location and time as an attribute,as well as computer cluster as system storage model,was designed in this paper.On the basis of analyzing the traditional spatial data record mode,the connotation and advantages of the space-time record system were discussed,and the system architecture and functions of the space-time record system were designed in detail based on the global subdivision model and GeoID coding so that it could provide technical reference for the management and organization of the global massive spatial data.
