摘要
针对测量工作中人工进行高斯投影、坐标换带和平面子午线收敛角计算非常麻烦又容易出错的问题,采用迭代法趋近求值,用BASIC语言编制了相应的计算机程序,实现了上述计算。该程序可用于便携式PC-1501计算机,输入简便,能直接得到通用的坐标和数据。实践结果表明:其计算精度合乎要求,计算速度比人工计算提高几百倍。
In view of the tedious and mistakable manual calculation in measuring Gauss projection,coordinate zone transformation and meridian convergence,an itera-tive approximation method is adopted and programmed by BASIC to imple-ment the direct and converse calculation of Gauss projection and computer cal-culation of meridian convergence angle. It can be operated on portable com-puter PC-1501 and has the merit of simple for input,to get the universal coor-dinate and data directly.Through practice ,it is shown that the accuracy of calculation meets the requirement,the speed of calculation is quickened a hun-dred-fold to manual putation.
