摘要
分析了影响平面测量坐标系选择的所有要素,介绍了目前世界上常用的地图投影方式,结合公路的特点,建议公路平面测量坐标系的选择应根据测量区域地理位置、海拔高度以及公路工程的要求,选择合适的参考椭球、抵偿高程面和投影方式。
All elements of determining plane coordinate system are analyzed,the projection modes in common in the world are introduced, and it is proposed that the plane coordinate system is selected by selecting appropriate reference ellipsoid ,surface of highness, projection mode based on geography position of survey area, highness, demands in highway survey.
