文章利用VC++编程语言实现了纵断面测量数据里程误差的自动平差处理，该程序可以对纵断面测量数据进行检查、分析和平差。在里程误差不超限时，利用平差程序实现纵断面测量数据的里程平差。-Articles by VC++ programming language of the longitudinal distance measurement error of the automatic adjustment of data processing, the program can be checked on the longitudinal measurement data, analysis of peace poor. When the error is not overrun in the mileage, the use of longitudinal survey data adjustment program to achieve the mileage adjustment.
