The topographic differences in German Wadden Sea between 1999 and 2006 are compared and analyzed in this paper. The waterline method is used to generate topographic maps of this area with SAR images. 13 SAR images (from ERS-2) of the year 1999 and 14 SAR images (12 from ERS-2, 2 from ENVISAT_ASAR) of the year 2006 are analyzed. The SAR images captured at different dates are able to cover different...
The waterline method is used to derive the topography of the tidal flats along the German coast by evaluation of SAR (Synthetic Aperture Radar) images. A series of SAR images taken at different water levels from 1996 to 1999 and 2009 is analyzed with a wavelet based edge detection algorithm to identify the border between the tidal flat and adjacent water areas. The waterlines detected are combined...
