摘要
在大面积林区进行测量工作时,密集高大的树木限制了GPS技术的应用。测区的控制测量及与国家三角点的连测方法,成为影响工作进度、保证测量精度的关键。利用无定向导线网和少量孤立的GPS点完成测区的控制测量并与已知点连测,可大幅度提高控制测量的效率和精度。
The application of GPS technology is restricted by the dense and tall trees when measuring works is carrying out in large forest. The method of connecting observation between conventional control points and National Triangulation Station would affect the working process and mapping precision.While a few of isolated GPS control points and non-orientation traverse network are reasonably used, which can compose the control network and enhance the efficiency and precision of control surveying.
