INTEGRATED SHIPBOARD MEASUREMENT TECHNOLOGY AND ITS APPLICATION ABOVE AND UNDER WATER:A CASE FROM CEZI ISLAND OF THE ZHOUSHAN ISLANDS

In recent years, the integrated shipboard measurement technology of aboveand under water integration has rapidly developed in marine geological survey and mapping. The technology aims to reGalize seamless measurement above and under water through integration of multi-beam water depth measurement system, laser scanning system and positioning system.Taking the Cezi island as an exGample, this paper provided a successful case for the seamless measurement above and under water, which realized the in tegration of water depth and topographic results.The advantages and disadvanta -ges of this technology as well as its future application are clarified and discussed.
