坐标正算工具，根据测站点坐标，测量的水平角，测量的距离，计算出待定点的坐标。测量数据存放在一个文件中，计算结果输出到结果文件中。(Coordinate is a tool, according to the measurement site coordinates, the measurement of the horizontal angle, measure the distance, calculate the coordinates of the points to be fixed. The measurement data is stored in a file, and the result is output to the result file.)
