Hello! I will write a supervised classification programme and want to
read a multi-band ETM+ image with IDL. But ENVI_GET_DATA function can
only read one band. It seems that READ_IMAGE function also read gray
image or RGB imge only. How can I read a multi-band image at one time?
I am new in IDL. Thank you very much.

Also take a look at ENVI_GET_SLICE, which will retrieve any or all
bands for one line of your data cube (convenient when you want to
process one line at a time rather than creating memory issues trying
to load the whole image at once).
