Hi All, I am a newbie in remote sensing and wanted to resample my Landsat visible bands to match in situ bands (the two center wavelengths are different). I need this to reasonably compare remote sensing reflectance from atmospheric correction methods (for many images) and in situ reference data (from AERONET-OC site). More specifically, bands from AERONET-OC instruments are 441nm, 491nm, 555nm; whereas corresponding bands from Landsat-8 are centred at 443nm, 483, 565... I have been trying the 'spectral resampling tool' in ENVI but looks like I didn't get how my ASCII file (text file containing bands and possibly FWMH) should be arranged, so my output pixel is always zero. Any insights on how to do this using any method will be greatly appreciated
