In this paper, a research has been conducted to find out the optimal projection parameter of KTM2012. An Unified rectangular coordinate system based on the Transverse Mercator projection is designed to cover the whole area of the Korean Peninsula as a single coordinate zone and at this time distortion quantities are minimized. In the case of using the central meridian and scale factor defined in the present UTM-K, the Range of scale correction shows about 1,920ppm and mapping distortions are not distributed evenly. Since central meridian lies along UTM 51.85 Zone, which has a central meridian 127.5° East of the Korean Peninsula with a scale factor of 0.9996 applied on the central meridian. With regard to scale correction, UTM produces the smallest scale correction, of -400ppm or 40cm per km on the central meridian and Dok-do, which means the island of isolation in the East Sea, produces the largest scale correction, of 1,520ppm. On the other hand, a newly derived projection with the Range of scale correction which is about 1,540ppm can be obtained when the true origin and central meridian defined in the KTM2012 are maintained, thus distributing the distortions due to the projection evenly.
