GPS应用中经常涉及到坐标转换问题。利用局部区域GPS控制网数据求解坐标转换模型的转换参数时,精度受很多因素的影响。本文介绍了七参数基本模型,并基于济宁矿区的北京54和WGS-84坐标数据讨论了坐标转换模型的不同求解方法以及公共点选取对坐标转换精度的影响。
GPS應用中經常涉及到坐標轉換問題。利用跼部區域GPS控製網數據求解坐標轉換模型的轉換參數時,精度受很多因素的影響。本文介紹瞭七參數基本模型,併基于濟寧礦區的北京54和WGS-84坐標數據討論瞭坐標轉換模型的不同求解方法以及公共點選取對坐標轉換精度的影響。

Coordinate transformation are often involved in GPS applications.Using GPS control network data in local area to solve the coordinate transformation parameters,the accuracy is affected by many factors.Combing Beijing 54 and WGS-84 coordinate of Jining mine,the basic seven-parameter model is introduced in this paper,and the effect of coordinate transformation model and common points selection on transformation accuracy is also discussed.
