2) Survey circleand curve lines
测设圆曲线
3) measuring and setting curve
曲线测设
1.
By analyzing the process of measuring and setting curve and calculating coordinates,It give a brief summary on the program design----calculating the azimuth angle and discussing the turning direction and quantity,so the complex classify of mirror laying point station and formula can be avoided,and program and calculation also can be simplified.
通过对曲线测设和测点坐标计算过程的分析,把坐标计算的程序设计归结为有向直线与X轴顺时针夹角即方位角的计算和线路转向转角的计算,弥补了测点位置和计算公式分类复杂等不足,简化了程序设计和计算过程。
