Nepal to ascertain height of world’s tallest peak

Nepal: In an attempt to calculate the exact height of Mount Everest, Nepal launched a two-year geodesic survey to measure the Himalayan peak.
Mount Everest, the world’s tallest mountain was named after British surveyor George Everest in 1856, when a trigonometric survey put its height at 8,840 metres (29,002ft). But when last measured in 2005 by China’s state bureau of surveying and mapping, its rock height was calculated at 8,844.43m (29,017ft), plus a 3.55m ice cap. This was still 7cm less than the elevation determined by an Indian survey in 1955.
To complicate matters further, in 1999 an American expedition to Everest using GPS technology for the first time got a rockhead elevation of 8,850m, and an ice elevation 1m higher.
It does not help either that due to shifting tectonic plates, Everest grows by 4mm every year. Nevertheless, the Chinese insist their calculations are the most accurate – a claim that has caused some high altitude friction between Nepal and China, as Everest straddles their common border.
Gopal Giri, a Nepal Government’s spokesman, said, “China, in its border talks with Nepal, has always been demanding to measure the rock height without snow of Mount Everest. Now that Nepal has become technologically capable of measuring the mountain, there was no need to depend on measurements taken by foreigners.”
