Cadastre, engineering survey, topographic mapping (large and medium scale).
Sometimes incorrectly assumed to be Tokyo 1918 / Korea East Sea Belt, a system that was never put into use. In South Korea, replaced by Korean 1985 / East Sea Belt (CRS code 5167).
Cartesian 2D CS. Axes: northing, easting (X,Y). Orientations: north, east. UoM: m.
