I am trying to do an atmospheric correction of WV-2 images with FLAASH. 1.-I convert the WV-2 data from DN to radiance using Worldview radiance tool in Envi 4.8. I specify the output to floating point. 2.- I convert to BIL format Resulting radiance image statistics Basic Stats Min Max Mean Stdev Band 1 0.000000 40.228760 3.139071 3.520640 Band 2 0.000000 47.530544 3.079424 3.595684 Band 3 0.000000 31.559774 2.052670 2.740032 Band 4 0.000000 27.919588 1.157554 2.023804 Band 5 0.000000 39.357430 0.843777 1.805708 Band 6 0.000000 23.645294 0.564779 1.497296 Band 7 0.000000 25.341818 0.420495 1.445683 Band 8 0.000000 18.583788 0.247936 0.906226 3.-After, I run FLAASH. I turn the aerosol retrieval to NONE and water retrieval NO FLAASH atmospherically corrected image statistics Basic Stats Min Max Mean Stdev Band 1 -360 17952 273.143183 447.251877 Band 2 -725 16039 335.101551 561.370635 Band 3 -285 10573 287.733010 620.919780 Band 4 -471 10180 153.661365 613.187281 Band 5 -609 15221 116.479420 616.986604 Band 6 -569 12468 118.702748 741.644475 Band 7 -413 14014 116.772068 773.215352 Band 8 -328 16954 117.193626 801.550638 FLAASH uses a default value of 10, 000 for the output scale factor. So, I have divided the data by 10,000 for get to percent reflectance which should range between 0-1.0 (17952/10,000=1.79, 16039/10,000=1.60, etc.) How can I interpret this response? Any help would be greatly appreciated. oli
