摘  要:
GPS技术定位精度高、速度快 ,且不受气候、通视条件限制。GPS控制网相对定位精度可达 0 1~ 1mm/km。GPS控制网应用于山区水土流失监控测量 ,必须将WGS -84坐标系转换为实用的国家或地方坐标系 ,并注意基准点的选择与检验。介绍了平面基准点的检验方法。

摘  要:
The positioning of GPS technology has high precision, fast speed, limited sight conditions and GPS control net. The relative positioning precision can reach 0.1~ 1 mm/km. The GPS control net is applied for monitoring and measuring the soil and water loss of mountainous regions. It must turn WGS-84 coordinate series into practical state or local coordinate series. In the meanwhile, it should select and examine datum points. The paper introduces examination methods of ground datum points.
