Dear Moderator!! Last night, i was working on radiance calibration of landsat8 OLI to run the FLASH module. But in new interface of envi 5.0. sp3 (32 bit), the radiance calibration module converted landsat8 image into flash format (BIL) of radiance with scale factor (SF) of 0.1. I put this file into Flash and choose the same scale factor of 0.1 but earlier with landsat 5 and 7, we put the SF value of 10. which SF one can use for landsat8?? I used lfilter function ldcm_oli.sli located in the \envi50\classic\filt_func directory. Further, the flash calibrated bands (1-4) are only showing the reflectance values in spectral profile and some water pixel is showing negative values. what should i do?. I already installed landsat8 oli hot fix. I also applied quick atmospheric correction on the same file. The spectral profile is showing values in all bands (1-7). Please try to solve this mystery. Thanx in advance!!
