摘要
空间直角坐标系与大地坐标系之间的相互转换是大地测量中的常规计算,经常采用迭代的计算方式忽略了纬度与大地高之间的相关性。而采用同一坐标系中由空间直角坐标计算纬度及大地高的推导算法,将纬度与大地高绑定参与迭代计算,编写了相应的计算程序。该算法经过了实例验证,公式推导简单,便于记忆、理解和程序编写,为空间直角坐标转换至大地坐标提供了新的思路与借鉴。
The mutual conversion between spatial rectangular coordinate system and geodetic coordinate system is the routine in geodetic surveying. However, the iterative algorithm neglects the relevance between latitude and geodetic height. Applying the algorithm of spatial rectangular coordinate to the computation of latitude and geodetic height in the same coordinate system, and combining latitude and geodetic height in iterative computation, the corresponding computing programs are developed. Through example verification, this algorithm facilitates the formula derivation, memorization, understanding and program development, which serves as a new line of thought and reference for the conversion from spatial rectangular coordinate to geodetic coordinate.
