针对单纯遥感图像处理方法中存在的不足，提出了一整套利用地理信息系统（ＧＩＳ）技术辅助进行水深遥感研究的方法，并将其应用于长江口的水深遥感研究工作中．研究实践表明：ＧＩＳ技术很好地弥补了单纯遥感图像处理方法的不足，提高了数据处理和信息提取的效率和精度．
Aiming at the shortcomings of simple remote sensing image processing methods, a set of methods of using GIS to assist the research of water depth remote sensing is proposed and applied to the research of water depth remote sensing in the Yangtze Estuary. Research practice shows that GIS technology makes up for the shortcomings of simple remote sensing image processing methods and improves the efficiency and accuracy of data processing and information extraction.
