On January 24, 2019, China‘s General Office of the Ministry of Natural Resources issued a notice on the Technical Outline of the Construction of a Smart City Space-time Big Data Platform (2019) (abbreviation as “Technical Outline” below). Once released, this Technical Outline becomes the guideline for our daily work and study.
In the report of the 19th National Congress of the Communist Party of China, Xi Jinping, the president, proposed to promote the deep integration of the internet, big data, artificial intelligence, economy, and build a smart city and a digital China. Cities are the most active area for social development; therefore, the construction of a smart city is an important part of building a smart society, and space-time big data platform is the fundamental support for the construction and operation of smart cities.
Since 2013, more than 500 cities across the country (China) have been building as smart cities. There are many supporting documents at the national, such as the Interim Administrative Measures for National Smart Cities Pilot (2012), the National Smart City (District, Town) Pilot Index System (2012), the National Standard for Smart City Evaluation Models and Basic Evaluation Indicators (2017), National Standard for Smart City Top Design Guidelines (2018), as well as the latest Technical Outline. The official release of the Technical Outline from the central government gives the official guidance and standards for the construction of a smart city big data platform to support local governments, related institutions, and companies.
It is generally believed that the overall structure of a smart city includes the following aspects: 1) The perception layer, that is, the collection of real city data through various IoT devices or human activities; 2) The data layer, the diversified massive data convergence to form the urban data pool; 3) The operating system layer, which restores urban digital-twin through GIS, etc., and visualizes and analyzes the urban data pool orderly, and realizes data convergence and discovery; 4) Application layer, which introduces smart city to government (to G), the business (to B) and the public (to C) to make the city smarter, more efficient and better.
The Technical Outline clearly states that the space-time big data platform is the basic support for the construction and operation of smart cities. It will realize planning, layout, analysis, and decision-making. Based on Space-time GIS, the big data platform realizes the upgrading and transformation of the smart city operating system.
Taking this opportunity, I reread the academic report of the Operating System: Smart City GIS written by Academician Guo Renzhong at the GTC Conference in 2018, which gave me a deeper and more comprehensive understanding of the background and significance of the Technical Outline. As a pioneer in China’s GIS, and also the first academician of the GIS industry, Dr. Guo has been engaged in research on geoinformatics theory and engineering applications. In recent years, he led his team to focus on the research and development of smart city big data platform based on the virtual urban environment.
In the past 20 years, information and communication technology (ICT) has developed rapidly, and 5G has also entered the commercialization cycle ahead of this year. Urban informatization driven by ICT is also rapidly evolving, and urban informatization is the integration of many information systems, that is, the system of systems. There are many operation systems based on the same infrastructure and database, which makes smart cities need an operating system (OS). This operating system requires GI. It also needs to visualize the urban geographic environment, ground integration, indoor and outdoor integration, sensor interconnection and data integration, and open secondary development framework.
I came from the traditional real estate industry. In 2015, I found my interest in city informatization construction. Now, I am in the 51VR Digital City Division, and fortunate to participate in the new round of smart city construction and upgrading. With the continuous evolution and popularization of new technologies such as 5G, Internet of Things, VR, AI, and cloud computing, advanced concepts such as digital twin, mirror world, and space-time big data platform implement continually. Smart city operations are built on IaaS (infrastructure) and have gradually moved on to DaaS (data service), SaaS (software service) and PaaS (secondary development API).
The following is a review of the theme report of Academician Guo Renzhong at the GIS Software Technology Conference——Operating System: Smart City GIS, in August 2018. Let’s read and learn together!

Academician Guo Renzhong comprehensively analyzed why smart cities must have an operating system?
Smart city is an higher stage of urban informatization. It is the integration of several information systems. It is a systematic information system ecosystem. Based on common facilities and data resources, there are a lot of general operations, which requires an operating system. Since the city is a geographical space, it needs to be digitally represented in the physical city. Each urban object have a position. All data is a description of the object. Therefore, the urban problem is a spatial problem, and the spatial relationship must be concerned.
The current GIS platform is not yet fully qualified for all the needs of smart cities. In the future, the GIS platform should be the core to create an operating system for smart cities. This is a very important task, its core elements and capabilities are: data integration and integration, visual expression, and an open secondary development environment.
In the report of the GIS Software Technology Conference in August 2018, Academician Guo Renzhong shared the application of GIS in various stages of e-government, digital city and smart city in China, pointing out the mainstream smart city service providers Ali, Tencent, Huawei, ZTE, Ping An, etc. The GIS is everywhere in technical solutions. GIS is also ubiquitous in solutions for typical cities such as Fuzhou, Wuhan, Shenzhen, and Xiong’an.
