Measuring Mount Everest Techniques

The video discusses Mount Everest, the highest mountain on Earth, and the complexities involved in measuring its height. Traditional methods like trigonometry have been used since the 19th century, with George Everest being the first to measure it. Modern techniques include photogrammetry and GPS. Despite the widely accepted height of 8,848 meters, there is ongoing debate due to factors like snow cover, erosion, and earthquakes. Recent efforts by Chinese surveyors during the COVID-19 pandemic aim to provide a more accurate measurement.
