Abstract

Abstract: 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 theearth 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.
