Abstract: | This paper demonstrates the theoretical basis of land subsidece measurements using GPS, the results of a typical study area are illustrated afterwards. Through comparison of the value extracted by conventional precision leveling with the one extracted by GPS, coherence to gain subsidence curve between both methods is summed up. The accuracy of GPS to monitor subsidence under normal condition is discussed in the end. |
