Development of the Intelligent System for Estimating the Parameters of Ocean Internal Wave

For forecasting parameters of the ocean internal wave from the geometric corrected MODIS remote sensing images, an intelligent system had been developed. The intelligent system was based on the MODIS remote sensing image with the latitude and longitude information. The MODIS remote sensing images were corrected by ENVI. The intelligent system was developed by the authoring tool of Multimedia ToolBook (MTB). The user could drag and place the magic point in any position of the remote sensing image. The coordinate values of the magic point could be read in the fields in intelligent system. For developing the intelligent system, many methods had been studied. The methods include the angle bisector method, geometrical center method, linear fitting method, determining the circle center by three points, and analog displaying technique. They show quickly and accurately the internal wave parameters in the intelligent system after the magic point is dragged all characteristic points. These characteristic points were in the feature lines, DongSha Atoll, and the crest of the ocean internal wave. The results show that the intelligent system developed by MTB could be used for forecasting parameters of the ocean internal wave such as the propagation direction, the maximum length of the crests, the distance from the DongSha Atoll, and the spacing of the crests.
