摘　　要：利用谷歌地球实现测量控制点可视化管理的一种方法:首先将BJ-54坐标转换为Google Earth支持的WGS-84坐标,然后用KML语言和VC++批量生成控制点地标并将其导入Google Earth中。与传统的利用点之记的方法相比,这种方法更加简单方便,精度高,寻找测量控制点更加迅速;与手工单个标注的方法相比,批量标注的方法效率更高,更适合用于对整个测区控制点的标注和管理。A method for visual managing the surveying control points using the Google Earth is introduced in the paper. At first the coordinates transformation between BJ-54 coordinates and the WGS-84 coordinates is being carried out; Then by using the Keyhole Markup Language and VC＋＋, the placemarks of Control Points are made and induced into the Google Earth. Compared with the traditional method of the description of station ,the method is more straightforward, more visual and more precise, so it is more easy to locate the desired control points. As the placemarks are being generated in patch automatically using VC＋＋ , the efficiency is much higher than the single placemark generated manually.
