基准点算法在测量平面坐标转换中的应用

Reference Point Calculation Method Applied in Switching Plane Survey Coordinates

简析测量坐标转换中典型的布尔莎七参数坐标转换公式。GPS动态定位中大部分进行的是平面作业,不需要点的精确高程,可采用简便的基准点算法进行平面坐标转换。经实例试算,证实了其可行性,具有一定的实用意义。

This paper introduces the typical seven parameters survey coordinate formula-Buersha Formula.The author points out the reference point calculation method in switching plane survey coordinates can be applied in dynamic location survey of GPS instead of point precise height.One example is given to confirm the method’s feasibility and practicality.
