Hi, supports
Does the Tasseled Cap tool works correct on the CASI data. There is only LandSAT sensor type available.
I want calculate Soil Brightness Index on the potato crop. I had read one paper where SBI were calculated using ENVI Tasseled Cap tool on CASI data. So, now i am wondering it is true or not. Maybe you could suggest witch bands should i use in some kind of equation.
Thanks for the answer.

The tasseled cap transform uses specific coefficients derived empirically from the specific sensors so I don't think it is appropriate to apply those to another sensor. There could be research out there that have looked into TS for Casi and if there are some known coefficients to use, then you could apply them using Band Math.

If i have coefficients, what kind equation should i use in Band math? Should i multiple original result band by this coefficients or how? I cant find it in envi help!
