摘　　要：针对数字孪生城市亟需空间统一框架与数据高效组织问题,基于地球空间剖分理论及相应的《地球表面空间网格与编码》(GJB8896-2017)、《北斗网格位置码》及《地球空间网格编码规则》等国家标准编制成果,提出发展一种数字孪生城市空间网格框架与GDS(Grid Data System)数据平台技术。城市多尺度立体剖分网格空间是一种地球空间的客观存在,城市万事万物在某一时间内一定落在某一或某几个网格体中,由此发展的GDS技术面向空间数据统一组织,有利于发展出面向空间建模的新型G-GIS、G-BIM等系统,是对传统GIS、BIM等面向对象建模数据系统的创新探索;有助于构建统一的空间数据框架进而实现城市多源异构数据的汇聚、关联与高效计算,对支撑数字孪生城市建设具有理论与实践意义。In view of the bottleneck problems of unified spatial framework and efficient data organization in digital twin ciy,this study,under the guidance of the new earth geospatial subdivision theory and the corresponding national standards such as "Earth’s Surface Spatial Grid and Code"(GJB8896-2017), "Beidou Grid Code(BGC)" and"Geospatial Grid Encoding Rule",proposes to develop an spatial grid framework for the digital twin city and the GDS(Grid Data System) data platform technology.The multi-scale 3D urban grid space is an objective existence of the earth space.Everything in the city must fall into one or several grid bodies at a certain time.The GDS technology developed from this is oriented to unified organization of spatial data,which is conductive to the development of a new type of G-GIS,G-BIM system and is an innovative exploration of the traditional BIM,GIS and other object-oriented modelling systems.This research could help to realize the unified and efficient collection,association and calculation of urban spatial data,and is of theoretical and practical significance for supporting the construction of digital twin city.
