| Abstract: | Based on data from 12 continuous GPS stations across Tianjin,the possibility of monitoring the land subsidence with GPS in this area is discussed.Then some strategies are used to produce the height time series and the result indicates that the WRMS of height is better than 3 mm.Through series the height changes during 2006 are presented and the land subsidence considence consists with that with leveling. |
