In response to a reporter's question, Liu Guohong, vice minister of natural resources, said: at present, the development of global digitization is accelerating day by day, and we are speeding up the construction of digital China.

According to Xinhua News Agency, Liu Guohong pointed out that the Ministry of Natural Resources will focus on promoting implementation in four aspects.

The first is to create a unified time and space base for the construction of digital China, build a national satellite navigation and positioning reference station "one network" based on Beidou, and speed up the construction of real three-dimensional China and space-time big data platform. to realize the interconnection between digital space and real space.

The second is to provide rich data elements for high-quality development, better support natural resources management, empower government management and decision-making, and help the development of digital economy to meet the needs of people for a better life.

The third is to create a good environment for the development of geographic information industry. We will establish and improve the basic system of surveying and mapping geographic information data, strengthen data supply, support the standardized circulation of data, and promote the healthy development of new business type.

The fourth is to keep the bottom line of surveying and mapping geographic information data security in order to build a new security pattern. Innovate data security technology and improve the service level of industry supervision.

CTOnews.com notes that real 3D can truly, stereoscopically and sequentially reflect the spatio-temporal information of human production, life and ecological space, and can realize the real-time association and intercommunication between digital space and real space through "man-machine compatibility, IoT perception, ubiquitous service".

According to the website of the Ministry of Natural Resources, by 2025, the construction of "Real 3D China" will achieve the following goals:

The topographic three-dimensional realization of 5-meter grid covers the land and major islands of the country.

Preliminary realization of city-level 3D coverage of cities above prefecture level with 5cm resolution

The national, provincial, municipal and county multi-level real-world 3D online and offline service system has been initially completed.

Cities at and above the prefecture level have initially formed the ability of real-time association and intercommunication between digital space and real space, providing a three-dimensional spatial positioning framework and analysis basis for digital China, digital government and digital economy.
