우리나라 平面直角座標에 관한 硏究

A Study on the Plane Rectangular Coordinate in Korea

우리나라 三角點의 位置表示에 사용되고 있는 가우스相以二重投影에 의한 平面直角座標의 實狀을 새로운 技法으로 整理, 分析하는 한편 그 結果를 土臺로 公共測量 등의 正確度 向上과 測量 實務面에서의 便益을 위하여 投影領城內에서의 測城線의 歪曲을 보다 적게 하는 새로운 投影法, 平面直角痤標系 및 線增大率의 導入을 試圖하였다. 本 硏究에서 提示한 새로운 投影法, 平面直角座標系 및 座標原點에서의 線增大率은 다음과 같다. 投影 : 가우스·크뤼거投影 平面直角座標系 : 8系 座標原點에서의 線增大率 : m0=0.9999

This article investigates the situation of the Plane Rectangular Coordinate derived from the Gauss Double Projection whereby the positioning of triangulation point in Korea has been represented on. Analyzing and assessing it have been performed by means of new computational method such as computer programing. On the basis of the results brought about, it is found that a new Plane Rectangular Coordinate as well as map projection and scale factor of geodetic length may be adapted to improve the distortion along the geodetic line on a certain zone of map projection in order to enhance the accuracy and the utility of the practical surveying works. The proposals for this study are as follows; (1) projection: Fauss-Krüger's projection (2) Coordinate system: Plane Rectangular coordinate with 8 origin system (3) Scale factor of geodetic length in origin; m0=0.9999
