Bands Selection to Invert Remote Sensing Model for Retrieving the Leaf Biochemical Components

MA Wei-wei1,ZHANG Lian-peng1,MA Xiang-hua2,CHEN Shi-cheng1,GUO Yang-yang1(1.School of Geodesy and Geomatics,Xuzhou Normal University,Xuzhou 221116,China;2.Production Department of Shanghai Dahua Sureying & Mapping Co.Ltd.,Shanghai 200136,China)  
The remote sensing radiative transfer model PROSPECT may be used to retrieve the biochemical components of vegetation leaf,the inversion accuracy may be influenced by the bands combination.A bands selection method based on the constrained least correlation of wavebands was proposed.Inverted results based on the selected bands were validated and compared with the results of full bands based method for simulation and measured data.The results showed that,for simulation data,the inversion accuracy of the proposed methods was above 99%;for measured data,the inversion accuracy of chlorophyll and water based on the selected bands was promoted slightly and the accuracy of dry matter was promoted significantly.
