Establishing the height datum for islands in Zhejiang through the method of tide-synchronized height transfer

• 1、Zhejiang Academy of Surveying and Mapping,Hangzhou, 311100, China

Abstract：Based on the analysis of sea level variations along the Zhejiang coastal region, this study employs the synchronous tidal datum transfer method. By selecting representative monitoring stations and conducting synchronous observations of tidal elevations across multiple sites, relative elevation differences between stations were calculated. This approach establishes a unified elevation datum surface consistent with the continental height reference system.
