Zusammenfassung:A railway central line type coordinate changing method using a railway reference point is provided to minimize an error since the confirmation location survey can be measured based on the computation land register map. A railway central line type coordinate changing method using a railway reference point comprises: a step of acquiring the geodetic coordinate(Bessel / TM) based on a railway reference point 350 point and assuming this as a linear axis; a step of calculating the amount of distortion by comparing a coordinate using the Bessel coordinate of a triple point with a result using only the country coordinate change coefficient; and a step of performing the coordinate conversion in bulk to digital terrain model and railway reference point based on the amount of distortion.
