| 摘 要： | 采用7参数布尔莎模型转换GPS坐标时，由于公共点情况复杂会对坐标转换精度产生影响。本文简述了采用布尔莎模型进行坐标转换的一般过程，结合工程算例考虑了公共点分布的几种情况对坐标转换精度的影响，提出了坐标转换分区进行的思想，得到了一些有益的结论。

| Abstract: | By 7 parameter Buersha model conversion GPS coordinates,the situation was complicated because the public point will have an impact on coordinate conversion accuracy.This article briefly elabrates Buersha model using the general coordinate transformation process,combining engineering example of the public consider several points in the distribution of the accuracy of coordinate conversion,coordinate transformation district raised the ideas,get some useful conclusions. |
