Measuring up a tall task for science

Fifty years ago, China announced its first precise measurement of Mount Qomolangma, also known as Mount Everest. Nowadays, China's ongoing measurement missions in the region remain important in understanding the evolving conditions on the world's tallest mountain.

China's persistent measurements provide precise elevation and location data that serve as a critical global benchmark for global geographic information systems and topographic mapping, ensuring the world's maps stay accurate, said Chen Gang, a professor at the China University of Geosciences (Wuhan). He noted that Mount Qomolangma grows a little every year.

The data aids in understanding plate movements and crustal deformation, while supporting critical research in geology, geography and meteorology, as well as applications in resource exploration and environmental conservation, Chen added.
