Abstract:This article takes time of observation into account on trend surface fitting, as a dynamic trend surface fitting model. The land subsidence data from the GPS monitoring system of Nansha is analyzed using the dynamic trend surface model. Our results indicate that the model could reflect the overall tendency of the settlement and have good spatial interpolation effects.
