The China Surveying, Mapping and Geographic Information Science and Technology Annual Conference hosted by the Chinese Society of Surveying and Mapping was held in Zhengzhou, Henan on October 16. According to the “Research Report on China's Surveying, Mapping and Geographic Information Technology Innovation and Industrial Development” released at the annual conference, China is expected to initially build a realistic three-dimensional Chinese system by 2025. Realistic 3D is an important new type of infrastructure for the country. It uses modern technology, such as remote sensing, big data, cloud computing, intelligent sensing, etc., to digitally present objects, spaces, etc. in the real world in 3D. It's like building a city or space in a digital world exactly like the real world. In recent years, China has comprehensively promoted the construction of a 3D reality China. It is planned to be initially completed by 2025, covering the country's land and major islands, and achieving 5 cm resolution city-level real 3D data coverage for prefecture-level cities and above.
