Abstract

This study couples Laplacian-of-Gaussian filter (LoG) and wavelet multi-scale edge detection approaches to extract the waterlines of Chongming Island from Landsat images. The digital elevation model (DEM) of the Chongming tidal flat is constructed by means of the "waterline method". From multi-temporal images obtained under different tidal conditions, it is possible to build up a set of heighted waterlines within the tidal zone, and gridded DEM is then generated by the Australian National University Digital Elevation Model (ANUDEM) method. The results indicate that the methods proposed by this paper can effectively reproduce the coastal near shore topography of Chongming Island, and the precision of the DEM of Dongtan tidal flat is acceptable.
