坐标转换在悬高测量中的应用

Application of Coordinate Conversion in Survey of Suspension Height

悬高测量是在目标点底部设置棱镜测量距离,再测定目标点的垂直角,计算出目标点的高程(高度)。但在目标点底部无法设置棱镜,悬高测量就无法进行。为此,文章介绍的悬高测量方法、计算原理和计算公式较好地解决了以上问题。同时讨论了其实际测量中的注意事项。

Survey of suspension height is to provide prism at bottom of target point for distance surveying,then the vertical angle of the target point is surveyed.Finally,the elevation（height） of the target point is calculated.Provided that the prism cannot be provided at bottom of the target point,survey of suspension height cannot be executed.In this paper,a new method for survey of suspension height,calculating principle and formula are introduced.This solves the above-mentioned issue as expected.Meanwhile,attentions in practical survey operation are discussed.
