Mount Qomolangma and even the whole Qinghai-Tibet Plateau were formed by the collision and extrusion of Indian plate and Eurasian plate. The extrusion has been going on, and the relative position of Mount Everest changes every year. According to experts, the moving speed of Mount Qomolangma is 4.2 cm per year, moving northeast, facing Changchun.

Second, why should Mount Everest re-measure the height of Mount Everest?

In 2020, the elevation survey of Mount Everest has entered the summit survey stage, and the survey mountaineering team will launch an impact on the summit in a suitable weather window in the near future to complete the last step of the field survey stage.

This measurement is 15 years later, China once again measured the height of the highest mountain in the world, which attracted much attention. So what is the relationship between surveying and mapping and our daily life? Xinhua News Agency reporters interviewed relevant people at the Everest Mountaineering Base Camp at an altitude of 5,200 meters to interpret the relationship between surveying and mapping and the daily life of ordinary people.

Surveying and mapping literally means surveying and mapping, including geodesy, topographic survey, aerial photography and remote sensing, geographic information and so on. It is the primary and basic service for national construction and development.

Taking the elevation measurement of Mount Everest as an example, it is not only as simple as measuring the height of Mount Everest. Before the summit investigation, the first national investigation team had done a lot of work at the foot of Mount Everest and other parts of Tibet. The results of global navigation satellite system, leveling, gravity and meteorological survey can be combined with previous data to serve the study of glacier change, earthquake, crustal movement and other problems. Accurate data of snow depth, meteorology and wind speed will also provide first-hand information for glacier monitoring and ecological environment protection.

Sharing the location allows you to see the other person's location intuitively, Didi taxi allows the driver to accurately determine which side of the road you are on, and the software that sells rice allows you to clearly know the distance from the food ... These conveniences that you can see and touch are all based on the data measured by the surveying and mapping team.

For the first time, the data provided by Beidou satellite navigation system, a global satellite navigation system independently built and operated by China, was used for Everest elevation measurement. In 20 19, the National Surveying Team 1 completed the construction of Xizang Autonomous Region Continuous Operation Reference Station, which filled the gap in the construction of Beidou system reference station in the last province in China.

Mount Everest was measured in different ways in different periods, and the altitude of Mount Everest was measured many times, which reflected the spirit of human knowledge and exploration of nature and became an important symbol of human understanding and understanding of the earth.
