地球物理数据处理中坐标投影计算方法初探

INITIAL DISCUSSION ON COORDINATE PROJECTION CALCULATION METHOD USED IN GEOPHYSICAL DATA PROCESSING

实际生产应用中计算投影时多存在一些问题和误区,本文简要说明了投影及投影距离的计算方法,并列举了生产中常见的两类问题算法,指出其存在的问题。同时编制了相关程序,利用野外实际测点坐标资料进行了较为详细的对比分析。结果表明所用算法在实际应用中更为合理,可以有效指导生产工作。

There are misunderstandings in projection calculations in practical production applications. This paper briefly introduced calculation method of projection and projection distance, listed two common calculation methods in production, pointed out existing issues, prepared relevant procedures, and made a relatively detailed comparative analysis using coordinate data of field actual observation spots. The results indicate that the used algorithm is more reasonable in practical application and effective in guiding production.
