Abstract The coastal terrain of Zhejiang is complex. It is impossible to use the traditional way to measure the tideland heights of many beaches or offshore islands. With UAV remote sensing technology and tidal observation, the tideland height can be measured, and the difficult problems of artificial measurement can be solved, thus greatly improving the efficiency. Firstly, in combination with existing data, the aerial region and tide information are determined.Secondly,the UAV aerial operations and tidal observations are implemented outside synchronization. Finally, the boundary between tide and coast are interpreted and drawn with high-precision remote sensing image data (DOM), the tidal observation data are interpolated to update tideland height. The results show that this technology can quantitatively describe the tideland height information and is hence a new method of tideland height measurement.
