As the Mount Everest elevation measurement is about to enter the summit, many viewers also have many questions. The biggest question is, why must someone climb to the top to measure? Can I climb to the top by helicopter? Can satellites and drones complete such high-risk tasks? See the expert’s answer.
　　Can satellite remote sensing images be measured?
　　Satellite remote sensing images are currently mainly used for surface monitoring, but it can obtain some information on the location of the surface. But for now, its accuracy is still not enough. The height accuracy that it can obtain is about two meters. In addition, it also measures the height of the snow surface, because there is no artificial to go to the peak, it has no snow depth measurement, so that it has no snow depth measurement, so that it cannot be released as a very accurate result. So as far as the current situation is concerned, using satellite remote sensing images to measure Mount Everest is not enough.
