Abstract: Land subsidence disaster has restricted the social and economic sustainable development.Leveling,GPS and InSAR technologies are widely used in leveling monitoring.To effectively indicate the accuracy of those technology on the time domain and space domain,this study proposes an integration of InSAR,leveling and GPS data processing method,to obtain high accuracy,high space-time resolution of ground subsidence monitoring.This algorithm instance at Guangzhou Nansha area,the feasibility and reliability are proved observably.

Key words: InSAR, leveling, GPS, precision processing, data fusion
