Dear All
I am trying to run a topographic correction on Spot 2 and Spot 5 images,
for this I have a DEM of my study site. I am using Envi 4.5 and Idrisi
Andes but I have not been able to find algorithms on any of this two
programs for this type of correction.
I have also read Fahsi et al 2000 and I would like to follow their
approach using the equation proposed by Yang et. al. 1993, but I have
had difficulties trying to estimate some of the parameters needed.
Can any one offer some advice on how to run a topographic correction? I
would really appreciate it.
Thank you very much
