    Automated Extraction of Shorelines from Optical and SAR Image

    Concluding Remarks
    Combining the segmentation and edge detection producers, we have proposed a scheme of shoreline extraction for each of SPOT images and SAR images. Experimental results indicate that the accuracy of the extracted shorelines may reach an accuracy of 1.5 pixels (for SAR images) or better (1.0 PIXEL, for SPOT images). Those results provide a sound basis for terrain analysis in the tideland areas when multi-temporal images and tidal measurements are available.
