2020 Mount Everest elevation measurement officially launched

Domestic surveying and mapping instruments and equipment comprehensively undertake this task

  Our Everest Base Camp, May 2 (Reporter Yuan Quan, Gu Yekai) The first press conference of the 2020 Mount Everest elevation measurement was held on April 30 at the Everest Base Camp, and the 2020 Mount Everest elevation measurement was officially launched.

  This year is the 65th anniversary of the establishment of diplomatic relations between China and Nepal. In order to implement the "Joint Statement of the People's Republic of China and Nepal", the Ministry of Natural Resources, together with the Ministry of Foreign Affairs, the State Sports General Administration and the Tibet Autonomous Region Government organized the 2020 Mount Everest elevation survey. This year is also the 60th anniversary of the first human climb to the summit of Mount Everest from the northern slope, and the 45th anniversary of the first accurate determination and announcement of the Mount Everest in China. It is of great historical significance to carry out the Mount Everest elevation measurement.

  In order to promote the smooth development of the Everest elevation survey and ensure the scientificity of the survey and the accuracy of the elevation results, the Ministry of Natural Resources has organized the elite forces of the China Academy of Surveying and Mapping, the Shaanxi Surveying and Mapping Geographic Information Bureau and the China Geological Survey Bureau, etc. Compile the design book and implementation plan of the Mount Everest elevation measurement technology. Experts in surveying and mapping technology and management led by Academician Chen Junyong and Academician Yang Yuanxi conducted a rigorous review and checked the "comprehensive use of GNSS satellite surveying, precision leveling, photoelectric ranging, snow depth radar surveying, gravity surveying, astronomical surveying, satellite remote sensing, "Traditional and modern surveying and mapping techniques such as the refinement of the geoid, precise determination of the height of Mount Everest" has been fully affirmed.

  The focus of the Everest elevation survey work is to achieve technological innovation and breakthroughs in the following five aspects: first, relying on the Beidou satellite navigation system to carry out survey work; second, domestic surveying and mapping equipment and equipment fully fulfill the measurement task; third, the application of aviation gravity technology, Improve measurement accuracy; Fourth, use real-world 3D technology to visually display the natural resources of Mount Everest; Fifth, survey and survey team members climb to the top to obtain reliable measurement data.

  The results of the Mount Everest elevation measurement can be used in the field of geodynamic plate motion research. Accurate data on peak snow depth, weather and wind speed will provide first-hand information for studies on glacier monitoring and ecological environment protection.

  The core of Mount Everest elevation measurement is the accurate determination of Mount Everest height, which is also a comprehensive surveying and mapping project representing the development level of national surveying and mapping technology. Since the founding of New China, the elevation measurement of Everest in China has undergone a transition from traditional geodetic technology to comprehensive modern geodetic technology. Each Everest survey reflects the continuous progress of China's surveying and mapping technology and highlights the highest level of China's surveying and mapping technology.
