Atmospheric Correction of Landsat 8 Satellite Images Based on the Acolite Model
Atmospheric correction is an important method to convert satellite sensor observations into true surface reflectance,and it is also a prerequisite for the construction of various satellite remote sensing prod-ucts.In this study,Linyi City was selected as the research area,and the Acolite model was applied to per-form atmospheric correction on Landsat 8 satellite images of various land targets such as vegetation,water bodies,and man-made surfaces.The correction results were analyzed and evaluated for accuracy.Through comprehensive comparison with the FLAASH model and Landsat 8 Collection2 surface reflectance dataset,it can be found that both Acolite and FLAASH can remove atmospheric effects to a certain extent.However,the atmospheric correction effect of the Acolite model is better than that of the FLAASH model,and its spectral curve of surface bidirectional reflectance is basically consistent with the trend of Landsat 8 Collec-tion2 surface reflectance data.Overall,the Acolite model has high overall accuracy in atmospheric correction of various land targets,and the scheme using this model has advantages such as easy operation and minimal manual intervention,which can provide technical support for the construction of various surface remote sens-ing retrieval products.
