解码航空物探遥感技术测珠峰

Decoding the aerial geophysical and remote sensing technology in measuring the Mount Everest

2020年,我国再次成功测量了珠穆朗玛峰的高程。2020年12月8日,我国和尼泊尔共同宣布,珠峰的最新高程为8 848.86m。在2020年珠峰高程测量的过程中,我国首次采用了航空重力和航空遥感综合测量技术,将两种技术所需设备搭载于我国自主改装的"航空地质一号"飞机上开展测量。航空重力测量填补了珠峰地区重力数据的空白,提升了珠峰地区高程起算面的精度至厘米级,为珠峰高程的精确测量奠定了基础;航空遥感测量获得了珠峰地区迄今为止精度最高的三维地形地貌数据。

China has successfully measured the elevation of Mount Everest again in 2020.On December 8th,2020,China and Nepal jointly announced that the latest elevation of Mount Everest is 8848.86 m.The integrated measurements of aerial gravity and remote sensing are first adopted by equipping the two kinds of measuring instruments on the self-modified called Aerogeology No.1 airplane in 2020.The aerial gravimetry filled in the blanks of the gravity data in the Everest region and improved the accuracy of the starting plane of the Everest elevation to centimeter level,which laid the foundation for the precision measurement of the Everest elevation.The aerial remote sensing measurements revealed the most accurate three-dimensional topographic and geomorphic data of the Everest region so far.
