Abstract

In this paper the comparison between videobased and GPS-derived shoreline measurements was performed on a sandy beach located in the Gulf of Pozzuoli (Italy). The comparison between video camera and DGPS coastline has been carried out measuring the error as deviation from the DGPS line computed along the normal to DGPS itself. The deviations between the two dataset were examined in order to establish possible spatial dependence on video camera point of view in the intertidal zone. The results revealed that, generally, the error increases with the distance from the acquisition system. The comparison shows that the proposed model correctly represents the cameras error in coastline image extraction process.
