利用从１９７３年至１９９３年美国陆地卫星ＭＳＳ、ＴＭ数据影象等不同片种、２０多个不同时期的伶仃洋遥感资科，结合同步或准同步水文观测数据，通过计算机、光学图象处理和遥感动态信息分析，获得对伶仃洋水沙输移特征和滩槽冲淤变化规律的宏观认识，其成果在伶仃洋治理规划研究中发挥作用。 From 1973 to 1993, the United States Landsat MSS, TM data images and other films, more than 20 different periods of Dingdingyang remote sensing information, combined with synchronous or quasi-synchronous hydrological data, through computer, optical image processing and Remote sensing dynamic information analysis, access to the Lingdingyang water and sediment transport characteristics and changes in the law of erosion and deposition macroscopic understanding of the results in Lingdingyang governance planning study to play a role.
