Michael,
If I'm understanding your problem correctly, this is a lot simpler than
you think. It sounds like you want to do some basic array
manipulation, like this:
Say you have two images, image1 and image2, that have the same column
and row dimensions, which we'll call xsize and ysize. You can make the
multiband image with simple code:
multi_band_image = bytarr(xsize, ysize, 2)
multi_band_image[*,*,0] = image1
multi_band_image[*,*,1] = image2
> From there you have lots of options. You can use IDL code to save the
image to a file and then use ENVI_SETUP_HEAD to write a header, but
like you suggest, using ENVI_WRITE_ENVI_FILE seems like the easiest
way. It'd look like this:
ENVI_WRITE_ENVI_FILE, multi_band_image, out_name='filename.img'
Is that what you needed help with? Or were you looking for how to setup
ENVI in batch mode? BTW, you can certainly write out a multi-band
image to a file without using ENVI at all...could that have been what
you were looking for?
