摘要: CIM基础平台的建设使得城市大量的时空与非时空数据汇聚,为智慧城市提供丰富数据源的同时,数据的融合使用也遇到了新挑战。本文针对CIM平台建设中多源数据融合存在的问题,利用地球网格空间编码规则、知识图谱、多源语义模型等先进技术和模型,重点研究空间网格与CIM数据融合的关键技术,在CIM1-7成果的基础上提出城市空间单元的概念,构建多层级的三维空间立体单元,实现以城市空间为基本单元的海量城市底板和城市空间的多种要素信息融合,为城市提供更便捷、更安全的城市信息基础服务。

Abstract: The construction of CIM basic platform has brought together a large amount of spatiotemporal and non spatiotemporal data in cities, providing rich data sources for smart cities. At the same time, the integration and use of data has also encountered new challenges. This article focuses on the problems of multi-source data fusion in CIM platform construction, and put up with key technology of spatial 3D grid and CIM data fusion using the geospatial grid encoding rules, knowledge graph, and multi-source semantic model. On the basis of CIM1-7 products, the concept of urban spatial 3D grid is proposed. By building multi-level three-dimensional spatial 3D grid, it can realize information fusion of mass urban base and multiple elements based on urban space, and provide more convenient and safer urban information services for various business applications.

Key words: urban spatial grid, earth grid spatial coding rule, city information model, data fusion, data sharing
