I have downloaded an modis hdf file.it is l1 and its name is MOD021KM ..I want to convert it to radiance.so I performed this steps in envi
Open>EOS>MODIS selected modis hdf file.then I tried to run Radiometric Calibration but when I select the image it says image must have gain and offset for each band.I tried to opent image from open>generic format>hdf but there is not any hdf format there.
Anyway.I think envi does not recognize gains and offsets.I have checked metadata of opened file and the table of gains and offsets is empty.
I am using Envi 5.1
Can you please help me to fix this problem?
