Automated Waterline Detection in the Wadden Sea Using High-Resolution TerraSAR-X Images

Figure 4

The algorithm’s results overlaid on the original image. The green lines show the sea-land-boundaries from our algorithm while the blue lines show the sea-land-boundaries from the SRTM landmask. This subsection of a high tide TS-X ScanSAR scene from November 2013 shows the area around the island Pellworm (middle) with sand banks and smaller islands. Our algorithm traces the contours of sand banks, islands, and mainland alike.
