Since 1913, the Original Spot of Water Level of Republic of Korea measured the height value of tide of the coast of Incheon for 3 years, and set the average value as zero(0.0m). This value was linked, installed(1963) on the land at the same level for direct height measurement, and 소 fixed value is 26.6871m.
The leveling is a way of measurement to find out the height information, which plays the essential role in various construction of seaside cities in accordance with global warming (rise of sea level) and facility management of sewage, land development such as measuring National Control Points, map producing, road and bridge construction.
