On July 18, the 17th China Smart City Conference, themed “Promoting Citywide Digital Transformation and High-Quality Development of Smart Cities,” was held in Changsha. Among over 400 national entries, the “Construction and Application of the Universal Platform for ‘One Map, One Code’ in Beijing Smart City” (hereinafter referred to as “the project”), by the Beijing Institute of Surveying and Mapping, stood out, winning the First Prize in the “2024 Smart City Pioneer Awards” for excellent case studies. This project was also the first case featured in the “China Smart City Excellent Application Casebook (2024).”

‘One Map, One Code’ are crucial components of the smart city’s infrastructure, and a key task outlined in the municipal government’s work report. Since 2021, under the organization of the Beijing Municipal Commission of Planning and Natural Resources and the Beijing Municipal Government Data Bureau. The Beijing Institute of Surveying and Mapping has been responsible for the project. The awarded project focuses on the citywide implementation of these tasks, tackling various technical challenges such as seamless comprehensive derivation, BJ2000 coordinate system vector-raster overlay, spatiotemporal identification coding, and multiple association matching governance. The project has successfully built a universal map for the smart city, providing general and thematic map services through the Beijing Municipal Government Geographic Information Resource Sharing Platform and the Beijing Platform for Common Geospatial Information Services (MapWorld Beijing) to various municipal departments and the general public. Additionally, the Institute has independently developed a city code spatiotemporal identification data service system, integrated with the city code platform of the Beijing Municipal Government Data Bureau, offering online spatiotemporal identification services for various smart city entities to municipal departments. As a key component and distinctive application of the national new basic surveying and mapping construction pilot in Beijing, the project offers a dashboard for over 50 municipal departments and 208 business systems in Beijing. It supports typical application scenarios such as grassroots governance with a unified code for Zuojiazhuang Sub-district and the construction of a spatiotemporal correlation base.

Throughout the project’s implementation, the Institute has actively studied national policies on the digital economy and smart cities, drawing on advanced experiences. Apart from strengthening top-level design, aligning with the overall and controlled plans of Beijing’s smart city, the project also establishes a systematic approach in a top-down fashion, using real-scene 3D as the new spatiotemporal infrastructure. By proactively crossing domains and enhancing communication with the Beijing Municipal Government Data Bureau, the Institute has set up a dedicated team, established a regular operational mechanism, and created a unified spatiotemporal foundation through standard-setting, process development, and service platform innovation, which supports the construction of a benchmark city for the digital economy and empowers the high-quality growth of the capital city!
