Abstract :
Different methods of delineation were used to extract shoreline features from images with different spatial and spectral resolutions acquired by airborne and spaceborne sensors. The exact location of the shoreline is difficult to obtain from the images and therefore the definition of shoreline was based upon the geomorphological and oceanographic characteristics of the area of study. Extracted shoreline vectors were then compared to existing official shoreline vectors to assess their accuracy and software efficiency. It is expected that the generation of shoreline vectors with a high accuracy will greatly improve the time of work and number of specialised personnel, and allow for the integration of the resulting shoreline vectors into cartographic databases.
