The earliest documentary records of Mount Everest began in the Yuan Dynasty, and its name was "Zeima". In 1714, the Qing government dispatched from Beijing the chief of the Academy of Sciences who had studied mathematics in Qintian overcame the presidency, Lama Zhur, Zangbo, and Lanben Chamba, and made a special trip to Tibet's local mapping map. Victor Sheng and others used the latitude and longitude diagram and the trapezoidal projection method to make preliminary measurements of their position and height under extremely difficult conditions at the time.
In 1717 (the 56th year of the Qing Emperor Kangxi), the map of the Emperor's Map was clearly marked by the Qing government. The location of Mount Everest was clearly marked and officially named Zhumulangmaalin (Alin) Manchu. For the big mountain). This map was made into Manchurian copperplate in 1719. It was made into Hanban in 1721. In 1733, it was made into a French map in Europe. On these maps, Mount Everest appeared in various languages ​​such as Manchu, Han, and French and identified the names.
In the middle of the 19th century, the British began to measure the Himalayas. Since they were telemetered in the plains of India and did not enter Tibet and Nepal, the names of these peaks were not known. The British used Roman numerals to arrange the numbers of the peaks of the Himalayas from east to west. Everest ranked 15th and was called the XV peak.
In 1852, the Indian Survey Bureau, headed by the Englishman Waffle, adopted a fine “triangulation†method (which takes into account factors such as curvature of the earth's surface, air refraction, and plumb line measurement deviations) to measure beads on the plains of India. The height of the peak is 8840 meters and it is the first time that it is the highest in the world.
In 1858, the Indian Survey Bureau designated the XV peak as "Mount Everest" in honor of the director of the Indian Survey Bureau, the British Colonel George Everest, who measured the peak.
In 1949, American Leona Clarke measured 193 meters above the Mount Everest based on traditional methods. He believed that Mount Everest was not the highest in the world, but his measurement was later confirmed to be overturned.
In 1954, based on the measurements made by the Indian Survey Bureau in 1852, the re-measurement of Mount Everest was 8847.6 meters.
In 1975, China organized the Everest Mountaineering Team again under the principle of "mountain climbing, surveying and mapping, and scientific exploration." On May 27th, after the 9 Chinese players completed the collective summit, in order to accurately measure the height of the highest peak of the earth, a 5m high metal cage with a red cage was prepared and placed on Mount Everest. At the top, surveying and mapping experts distributed on 10 surveying and mapping points at different distances in the mountains, mountains, and peaks performed fine measurements on the target, and finally measured the height of Everest at 8848.13 meters (based on the Yellow Sea's sea level). . On July 23, 1975, the Chinese government authorized Xinhua News Agency to announce to the world that China’s surveying and mapping workers accurately measured the highest peak in the world—the altitude of Mount Everest was 8845.13 meters. This height has become a world-recognized authority height. Since then, this landmark has also stayed on top of the peak, becoming the highest point on Earth's highest point. Because it is 5 meters higher than the peak.
