As a spiritual symbol of Taiwan, Mt. Jade is the highest peak in Taiwan and in Northeastern Asia. The height of Mt. Jade was determined to be 3952.382m in 1978 by Trigonometric Leveling.
For conducting new orthometric height of Mt. Jade, NLSC implemented the survey, verification, and orthometric correction by combining leveling, satellite positioning, and gravity survey in 2003. As a result, the orthometric height of Mt. Jade is 3951.798±0.072m, where ±0.072m represents the precision of survey result.
To re-leveling the difference of the orthometric height of Mt. Jade after 14 years, NLSC implemented the survey in 2016 and 2017, the orthometric height of Mt. Jade is 3952.430±0.045m, where ±0.045m represents the precision of survey result.
For “the results of level reference survey for Taiwan class 1 level reference net in 2022” had disclosed by the Ministry of the interior, the difference of the orthometric height of Mt. Jade was re-leveled by NLSC in 2022, the result is 3952.433±0.046m, where ±0.046m represents the precision of survey result.
