    We use FLAASH to atmospheric correction of QUICKBIRD data, We got 81% also we did QUICKBIRD without atmospheric correction we got 71% accuracy. How do you think about this accuracy?

    What sort of accuracy are you talking about?  Accuracy in a classification?

    We did the atmospheric correction of QuickBird using dark subtraction (ENVI) and FLAASH (ENVI) and classified using maximum likelihood. The accuracy of output map (after classification) is 71% and 81% respectively. Also we did classification QB using maximum likelihood without atmospheric correction. The accuracy of output map is 71%. It is exaclty the same accuracy of output map which dark  subtraction classified using maximum likelyhood and  did atmospheric correction. It would be very helpful if you csn give me some comment.
