| Abstract: | 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. |
