首先本文介绍大地测量学坐标的相关知识，接着介绍了与坐标转换相关的知识以及坐标转换模型，最后着重研究布尔萨七参数模型，对其进行正反算程序设计及参数间的相关性分析，并利用VC++语言实现坐标转换的过程。

Abstract With the development of geodesy, the formation and development of global integration, the global mapping data form a unified specification, especially the unity of the coordinate system. , due to the different measurement standard of the selected reference ellipsoid also are different, so many different kinds of coordinate system. According to different requirements of surveying and mapping, the need to coordinate transformation of different coordinate system. In the process of coordinate transformation, under the same elliptical reference frame transformation, there are also under different elliptical reference frame transformation to each other, according to the requirements, the measurement of coordinate transformation is engaged in the work must master.
First of all, this paper introduces the related knowledge of geodesy coordinates, then introduces the knowledge related to coordinate transformation and coordinate transformation model, finally focuses on bursa seven parameters model, on the positive and negative numerical procedure design and parameter, the correlation analysis between and by using vc + + language to realize the process of coordinate transformation. 源￥自%六^^维*论-文+网=www.lwfree.cn
