位置主导的空时记录体系架构设计

针对传统空间数据记录体系在全球尺度空间数据管理中存在的弊端,如数据图幅范围缺乏大范围或全球统一标准管理、数据跨图幅接边处理复杂等问题,本文构建了一套以空间位置记录为核心、时间为属性、计算机集群为存储模式的空时记录体系。在剖析了传统空间数据记录模式基础上,探讨了空时记录体系的内涵与优势,并基于全球剖分模型及其编码(GeoID编码)着重设计了空时记录体系架构和结构功能,为全球海量空间数据的管理与组织提供了技术参考。

System structure of location-based space-time record

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.
