摘要
本文主要介绍了根据已知的地面点位坐标以及借助于复合Simpson公式如何得到线路中线点的坐标,从而确定地面点的里程和偏距。
This paper mainly introduce how to get the coordinates of points of central line according to the known coordinates of a ground point and with the help of compound simpson formula,thereby determing the mileage and offset distance of ground points.
