摘　　要：用手持式GPS自带的数据传输软件Mapsource,计算其坐标系转换参数,以追求最佳转换参数为目的,将计算由野外转到室内,通过转换参数与坐标误差之间的线性关系,建立转换参数的计算模型并优化,可达到任意区域WGS-84坐标与北京54、西安80坐标的简便转换,本文还对参数的适用范围做出分析。该计算模型简单,方法可靠,转换精度良好,适用范围分析合理。The coordinate system transformation parameters are calculated with the software Mapsource of hand-held GPS in order to achieve the best transformation parameter. The calculation is carried out from field to indoor. According to the linear relationship between transformation parameter and coordinate error,the calculation model of transformation parameter is set up and optimized, which can achieve the convenient transformation of WGS 84 and Beijing 54,Xi＇an 80 coordinate of any area. And we have an analysis of the applicability of parameter in this paper. This calculation model is simple,method reliable,transformation precision good,applicability area analysis rational.
