Until someone more qualified than me answers this, here is a link to
the FITS standards: http://fits.gsfc.nasa.gov/.

You centainly could put all this data in to a FITS binary table using
the routines in Wayne's library: http://idlastro.gsfc.nasa.gov/. The
process is relatively straghtforward. If you are working with
astronomers (I'm guessing here), we do like our FITS files, and have a
number of astronomy-specific tools for viewing them already.

Back to the OP's question, can't you just use writefits? I work with
FITS cubes almost exclusively, and that's what I use for such mapped
spectra. writefits adjusts the header appropriately for 3D data.
