Quantitative Retrieval of Chlorophyll-a Concentration of Taihu Lake Based on Satellite HJ-1Multispectral Data
With combination of satellite HJ-1 multispectral CCD data and synchronous ground monitoring data on water quality, combining the visible light red band (select the one that has a high correlation with measured chlorophyll-a concentration) and near-infrared band, this paper takes Band4/Band3 as arguments, establishing linear model and multinomial model respectively, furthermore makes a comparative analysis of them. The results show that the band combination method for inversion is feasible, based on the comparison of the two models, it is concluded that polynomial model has better effect. And by using ArcGIS software and polynomial modelmakes chlorophyll-a concentration profile.
