In the morning of December 5, 2019, Guilin Wang, Wengu Liu, Yangsheng You, Yali Zhang, Ronghua Yang and other teachers of Civil Engineering College of Chongqing University went to Chongqing Survey Institute and Chongqing Institute of Surveying and Mapping, MNR for investigation under the leadership of Prof. Wengang Zhang, the associate dean of the college.

They firstly arrived at Chongqing Institute of Surveying and Mapping, MNR. Mr. Hong Yang, the deputy dean of the institute, participated in the communication accompanying with the stuff who are working in the relevant departments and in charge of the production units. After introducing the situation of each unit respectively, the two organizations conducted in-depth communication on issues such as personnel training, disaster prevention and mitigation in the reservoir area, international engineering construction of the Belt and Road Initiative, scientific and technological innovation, and joint application for international projects, laying a good foundation for the next cooperation.

Then the teachers went to Chongqing Survey Institute. Mr. Zhiqing Zhang, the director of the Surveying and Mapping Management Office of Chongqing Municipal Planning and Natural Resources Bureau, and Mr. Zejun Xiang, the vice president of Chongqing Survey Institute, led some technical leaders to participate in the communication. They demonstrated their recent achievements and work in "full coverage, multi-source and multi-scale real-world 3D model", "big data platform of urban infrastructure security monitoring ", "mobile measurement system" and other aspects, laying a foundation for further cooperation.

Chongqing Institute of Surveying and Mapping, MNR, a subordinate institution of the Ministry of Natural Resources, is one of the first batch of units to obtain Class A surveying and mapping qualification in China. It used to be the Fourth Topographic Survey Team of the General Staff of the Central Military Commission, which was founded in 1954.
