The Extraction of Geomorphologic Remote Sensing Information on Shallow Sea Under-water Terrain and Its Application
浅海水下地形地貌遥感信息提取与应用

By using the data of the landsat and with the help of computer image processing method, the information of shallow sea's configuration and terrain are obtained in the areas of Chang Dao Island (Southern Bohai Strait), Ming Jian, Ou Jian and Pearl river mouth. In this paper, the auther discusses the characteristics of under-water terrain and the module of picking up water depth message. To obtain the better result, the multiseaonal and multispectral data are needed to pick up the information. It can be seen that the application of satellite remote sensing and image processing technology is one of the method of shallow sea investigation, and it's a useful supplement for ordinary investigation, especially for the investigation in the changeable and dangerous oceanic areas. Also, its applications in sea shore planning, developing and managing such as environmental monitoring and evaluating for acquatic culture in bay.
