What is the scientific research price of the Everest survey?

Everest elevation resurvey in 2005, the use of traditional geodesy and satellite measurements combined with technical methods, while using satellite navigation and positioning means and traditional optical means, set up a surveyor's beacon, prism, satellite navigation and positioning receiver in one of such a facility. Mountaineers brought it to the top of the mountain, using these several technical means to observe at the same time, a total of **** observed 30 sets of data. In addition, the mapping team also took the gravimeter to a height of 7790 meters, creating a historical record at the time, and for the first time in the summit of Mount Everest, the use of snow and ice radar detector to measure the thickness of snow and ice.

For a mountain, the highest point of the rock is its true height. And because Everest's summit is cold and covered in snow all year round, it's difficult to know how thick the snow and ice are by traditional means.

It is also true that Everest's height can change. The Himalayas, where Everest is located, are one of the tallest and youngest mountain ranges in the world, formed by the collision of the Indo-Australian plate with the Eurasian plate. Its tectonic movement has not yet ended and it is still rising, according to geological studies.

At the same time, the Himalayas are also in the plate boundary collision type earthquake tectonic zone. Under the influence of earthquakes, Everest will not only "grow taller", but also "shorter". The size of the change depends first on the magnitude of the earthquake, and the distance from the epicenter, the greater the magnitude, the closer the impact is greater.

The Everest elevation measurement, the domestic instruments to take full responsibility for the measurement,
