Original Vertical Datum of the Republic of Korea

A vertical datum (sujunwonjeom) is the reference point for measuring the elevation of the nation's land, installed on land in 1963 after surveying its difference from mean sea level. It is because of this vertical datum that the heights of Seoraksan Mountain in Gangwon State and Hallasan Mountain on Jeju Island can be compared. A hexahedral granite mounting block sits on a round base stone, with the datum point itself marked by an amethyst set into the top, and a modest circular brick structure protects it. The height of this vertical datum, which serves as the reference for determining benchmark elevations across the country, is 26.6871m.
