摘要

GF-2 satellite is the highest spatial resolution Remote Sensing Satellite of the development history of China's satellite. In this study, three traditional fusion methods including Brovey. Gram-Schmidt and Color Normalized (CN) were used to compare with the other new fusion method NNDiffuse. which used the qualitative assessment and quantitative fusion quality index, including information entropy, variance, mean gradient, deviation index, spectral correlation coefficient . Analysis results show that NNDiffuse method presented the optimum in qualitative and quantitative analysis.it had more effective for the follow up of remote sensing information extraction and forest, wetland resources monitoring applications.
