I noticed values in two entries are not matching with usual inputs: 1) Input file: wavelength: Blue:479.5 nm; Green: 546.5 nm ; Red: 654 nm ; Near IR: 814.5 nm (Values are taken from Quickbird imagery products:Product guide; modified 6/15/2007); I usually leave FWHM column free for MS sensor. 2) In FLAASH advanced settings, the sensor zenith and azimuth angles are set for nadir viewing sensor; but Quickbird is a non-nadir viewing sensor; the appropriate values for sensor zenith and azimuth should be given. Also you should check the quickbird.sli and quickbird.hdr file in the assigned directory (ITT\IDL70\produtcs\envi45\filt_func) for any kind of error. Hope this may help!

Thanks alot aniru123, I've corrected the 1) and 2) , i checked the directory for quickbird.sli and .hdr files too, however i still received the same error report during the processing. Is there any other solution available ??

Ok...you can do one thing; go to advanced settings of the FLAASH and increase the tile size from 150 Mb to say 1000Mb or like that (hit and try with some larger arbitrary tile size) See this: http://www.ittvis.com/ser...echtip.asp?ttid=3930

Thank you again Aniru123 Im trying to increase the tile size from 100 to 700Mb onwards, however so far (700Mb) still encountered with the nonblank pixels error report. The limit is the 1000Mb. When i increased directly to 1000Mb the PC memory allocated is not enough. Is that any other suggestions ??

does anybody has the "filter function file" used for atmospheric correction of quickbird data? Thanks

It's already there in ITT\IDL7.x\products\envi4x\filt_func folder if you have ENVI (probably versions 4.5 or later) installed.
