Hi. I have a question about the radiometric indices tool. I want to calculate TSAVI on a Landsat-8 image but I don’t know how OTB calculates it. Are the parameters of the radiometric indices set to some default values?

Hello,

there is no way to modify the parameters in the application, looking at the code the parameters are:

`A = 0.7`

`S = 0.9`

`X = 0.08`

Okay. Thank you very much. So if I need to calculate TSAVI, I am going to have to calculate A and S(slope). I think it’s done through quantile regression but I don’t know if there are other ways to do it…
