The elevation datum is an important component of the surveying and mapping datum, providing data support for maior national proiects, Addressing the issue of accurately monitoring elevation datum affected by factors such as surface deformation, we present a study to analyze surface deformation based on time-series InSAR data and leveling time-series data. The study conducts periodic re measurement of elevation datum in deformation area, achieving dynamic monitoring primarily through updating elevation datum, point usability analysis, and point subsidence analysis. Taking Shandong province as an example, we carry out an experiment, The results show that the method proposed in this paper can effectively reduce monitoring costs and difficulties, yield reliable results, significantly enhance the supportability and service quality of surveying and mapping datum, and provide a new dynamic monitoring approach for regional elevation datum.
