Abstract
This paper not only analyzed four types of land subsidence technologies such as leveling, GNSS, InSAR and layerwise mark, but also compared the observation accuracy, spatial and temporal resolution and. This paper studied data fusing and interpolation calculation, then put forward a new data fusing theory and interpolation method. Using this theory fuses leveling and InSAR land subsidence data, receives and draws fusing land subsidence rate chart.
