The research of sediment concentration extraction application system of HY-1 satellite data

Regarding the area near the Yangtze River mouth as the demonstration region, this paper briefly introduces the algorithm for the extracting information of the sediment concentration, the main function of the extracting sediment concentration system and some pieces of key technology. Now the system has been trial running, and we get more accurate result, it gives a technique guarantee for the using of HY-1A data.
