GPS即全球卫星定位系统,操作简便快捷,布网不受常规通视条件的限制,观测可全天候进行,且定位精度高,有着经典测量方式不可比拟的优越性。近两年来该项技术逐步应用于地形测量并逐渐成熟,为地形测量的准确性和科学性提供了保障。在此基础上开展GPS技术数字化地形测量应用研究对地形测量有着重要的意义。
GPS is the global satellite positioning system, easy to operate, the network is not subject to the limitations of conventional viewing conditions, observation can be carried out around the clock, and high positioning accuracy, with the incomparable superiority of the classical measurement methods. Over the past two years, the technology has gradually been applied to terrain measurement and gradually matured, providing the guarantee for the accuracy and scientificity of terrain measurement. On this basis, the application of GPS technology to digital topographic survey is of great significance to topographic survey.
