中文摘要：

在进行GPS相关的各种应用中，由于GPS坐标采用WGS-84坐标系，而不同的应用所采用的坐标系不尽相同，所以需要进行WGS-84坐标系与实际采用的坐标系之间的转换．而对于不同的应用环境，坐标转换模型也不尽相同．作者在移动应用环境下．针对不同的起算数据和要求，提出了不同的GPS坐标转换模型，利用最小二乘法进行了坐标转换参数的求取与平差，探讨了坐标转换模型计算时应该注意的问题．利用所提出的GPS坐标转换模型，应用于上海某区绿化信息GPS采集，结果表明，所提出的模型在移动应用环境下具有较好的适应性与快捷性．

英文摘要：

In the applications related to Global Positioning System （GPS）, the GPS coordinates are in the World Geodetic System-84, but in different application environment will use different Coordinate System, so the transformation between WGS-84 and other Coordinate System with different Application is needed. In this paper, according to different initial data and request, different GPS Transformation Models are presented on Mobile Application Environment. Calculating and Adjustment of Transformation Parameters is implemented by using least square method and some key points in the model calculating are also discussed. The transformation model which pointed out in paper is applied to GPS virescence information gathering of certain district in Shanghai. The results show that the model has adaptability and facility under Mobile Application Environment.
