| Abstract: | In this paper,a framework of Three Gorges channel surface current velocity and direction data processing system is discussed.Furthermore,a corresponding strategy of automatic data processing is proposed,and a specific algorithm and systems are designed and implemented based on VB6.0,then a map is made by EPS2008.Finally,demonstration application is carried out on the surface current velocity and direction observation of Shipai water area between Three Gorges and Gezhouba dams under discharge 45000ma/s,and the accuracy of the data processing and efficiency of map-making is verified and confirmed. |
