Multi-spectral Remote Sensing Data Based Processing Method and Analysis of Water Quality Monitor

TONG Xiaohua1,XIE Huan1,QIU Yanling2,ZHAO Jianfu2(1.Department of Surveying and Geoinformatics,Tongji University,Shanghai 200092,China;2.State Key Laboratory of Pollution Control and Resource Reuse,Tongji University,Shanghai 200092,China)  
The paper presents a study of the spatial distribution of water environment on the basis of quantitative remote sensing theory and methods and multi-spectral remote sensing data and water monitoring data on the spot,and an analysis and estimation of the distribution data.The processing method of multispectral remote sensing data is presented and the regression model of water quality parameters is derived.Based on a case study of Lake Tai,the regression model of suspended sediment concentration is set up.The result shows that it is feasible to monitor water quality with the method of remote sensing,and the spatial distribution of suspended sediment concentration of Lake Tai obtained from the remote sensing data agrees well with the data in situ.
