高速公路中投影长度变形的处理
Handling of Lengthdeformation of Projection in Highway
【摘要】 介绍采用平移投影中央子午线和赫尔默特坐标变换公式,处理工程中投影长度变形和相邻工程衔接的方法。利用覆盖工程的长基线获得坐标变换的旋转角,利用工程控制网的关键点获得坐标变换的平移量。
【Abstract】 This paper describes formulas using projection translating of central meridian and helment coordinate transformation,which can be used to handle lengthdeformation of projection and connection of adjacent projects.It discusses how to get the angle of rotation in coordinate transformation by using the ways to overlap the long baseline of the porject.It also discusses how to get the translation value of coordinate transformation,by using the key points of the control network.
