Abstract:
GPS, the global positioning system, is simple and quick to operate, the
network is not limited by the conventional access conditions, observation can be all-
weather, and the positioning accuracy is high, with the advantages of the classical
measurement method incomparable. In the past two years, this technology has been
gradually applied to topographic survey and gradually matured, providing a guarantee
for the accuracy and scientific nature of topographic survey. On this basis, it is of
great significance to carry out the application research of GPS technology digital
topographic survey.
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。
