Hi,

We can perform the atmospheric correction for any multispectral sensor using FLAASH, but we need to provide the input parameters (i.e. Sensor altitude, pixel size, solar zenith and azimuth angles, sensor zenith and azimuth angles etc) by ourself. I have applied the FLAASH to the Chinese HJ1 A/B CCD sensors (please see the attachment) by customizing the FLAASH according to the sensor.

Have you considered to add the Spectral Response functions for LISS 4 and AWIFS bands?

Hope this helps!

 Dear Somnath, 

I suggest you try to apply 6S atmospheric correction if you are going work on vegetation analysis through LISS. Likely to get good result. There are lots of literature available on it. kindly go through.   

 Sir Majid Nazeer,

at the time for running the flaash I gave all the parameters which you have told but I can't understand which sensor type will I use , there is no option for LISS 4 selection. As there is no LISS 4 sensor type , there asking for providing file filter function as an input, but where and how will  get this ???

Hi,

you can a detailed description of your question in this reference.

Though I'm very late in answering but this was the same problem that I faced. You must have sorted out or worked your way around. but still I would like to share a publication helping with the answer:
