Assessment of landform change in tidal flat is crucial for ecological environment protection, coastal erosion prevention and development likelihood for local people. Multi-temporal remote sensing images are useful data to detect the change of tidal flat. This study aims to assess intertidal topographic changes by comparing digital elevation model (DEM) from 1988 to 2014. The DEMs were generated from Landsat images from 1988÷1990; 2000÷2001 and 2013÷2014 using the waterline method. Correlation between DEM in 2013÷2014 and field data reached the value R of 0.821. The area variation of tidal flat topography is presented by spatial indicators. (1) the change of area of tidal flat such as high tidal flat, middle tidal flat, and low tidal flat using overlay analysis. (2) volume change of tidal flat were detected by subtraction from DEMs. The area of tidal flat decreased 25.56 ha which shows erosion from 1988÷2001. Overall, 1000m3 of sediment deposited on the high tidal flat was indicated.
