北京智慧城市"一张图"建设与应用OA

In the process of informatization and smartization in Beijing City,various government departments have independently constructed geospatial data due to their business needs,leading to issues such as inconsistent technical standards,low utilization rate of repeated data collection,difficulties in information sharing and integration applications,and severe fragmentation across departments and regions.Considering the urgent demand for 2D and 3D maps in smart city construction,based on existing data such as remote sensing images,government electronic maps,city-level 3D real scene models,and domain-specific thematic layers,and relying on Beijing City's government geospatial sharing service platform,we continuously researched and tackled key technologies for the construction of a super-large scale spatio-temporal data resource ser-vice system tailored for the new smart city construction,automatic association and fusion of multi-source heterogeneous spatial data centered around building entities,large-scale spatio-temporal data storage and computation,and agile development tools for government spatio-temporal big data thematic applications.Ultimately,a unified spatio-temporal benchmark foundation was established to support and serve spatial business applications for government departments at all levels across the city,which constituted the smart city"One Map".This achievement has been widely applied in various districts,committees,offices,and bureaus in Beijing City,supporting multiple major events and key projects,and has been continuously optimized and improved in application,effectively supporting the refined governance and precise services of Beijing City.
