tasseled cap transformation

[TeresaChapman]

Hello,
I would like to conduct a tasseled cap transformation to numerous landsat images. I cannot find a built-in function in ArcGIS, although the online help claims such a function exists.
Des anyone know if this function exists or where to find it or how to do it if there isn't a function?
Thank you,
t chapman

Greetings,

It's easiest to put your landsat images into a mosaic dataset, then insert the function. Please read the information on the Tasseled Cap Function for usage tips. I provided a screenshot of where the function exists.

Best,
Eric

Please note that the coefficients are specific to a given sensor and cannot be applied to a different sensor. Additionally, input values for TM5 are assumed to be 8-bit digital numbers, whereas ETM7+ values are assumed to be at sensor reflectance.
