This study aims to extract the instantaneous shoreline from remote sensing data acquired with very high resolution multispectral and SAR sensors. The capabilities of IKONOS. GeoEye and COSMO-SkyMed for shoreline detection are tested in the Venice littoral (Italy) by classifying the imagery into its land/water components. GPS measurements synchronously to the COSMO-SkyMed acquisitions are carried out along two transects at different tidal levels and used for validation of satellite derived shorelines. Finally, a collection of instantaneous coastlines at a specific tidal level is mapped for reconstructing the intertidal beach morphologic model.
